There is even a site out there that says a positive mono test can be an indicator of lymphoma!! Since this positive test is unusual because it is my second time, this info drove me insane. But after reading your response, I feel better to know that having mono more than once isn't such a shocker Monospot test is a form of the heterophile antibody test which is used for the rapid screening of infectious mononucleosis (mono). Epstein-Barr virus (EBV) causes the disease infectious mononucleosis. Blood, serum, or plasma is taken and is looked for the presence of heterophil antibodies Epstein-Barr virus (EBV) is the virus responsible for mononucleosis. EBV can also (in addition to kissing) be transmitted through coughing, sneezing, or by sharing drinking or eating utensils. Most people in the United States are infected with EBV by the end of their teen years, although not everyone develops the symptoms of mono If monospot test results were positive, it may mean you or your child has mono. If it was negative, but you or your child still has symptoms, your health care provider will probably order an EBV antibody test. If your EBV test was negative, it means you don't currently have an EBV infection and were never infected with the virus A monospot is a test for heterophil antibody agglutination of red blood cells of animals. Timing is important for the test. Positive testing appears usually within 1 week of the onset of symptoms with a peak at 2-5 weeks and then waning usually over 3 months. Waning can occur for as much as 1 year
This test can show the presence of abnormal or immature cells, which may indicate an underlying condition, provide information about its severity and suggest the need for further testing. Complete Blood Count. A complete blood count (CBC) is a common test that gives a general picture of your health Monoclonal B-cell lymphocytosis (MBL) is an asymptomatic condition in which individuals have increased blood levels of particular subtypes of monoclonal lymphocytes (i.e. an aberrant and potentially malignant group of lymphocytes produced by a single ancestral cell). This increase must persist for at least 3 months This test is done when the person experiences symptoms of Leukemia. When the patient feels feverish, tired, dizzy, and experiences heavy bleeding and bruises, then this test is carried out to check whether a person is positive for Leukemia or not
Typically a sample of blood is looked at under the microscope and if the test is positive you will see the abnormal lymphocytes cells that are referred to as smudge cells. In most cases, people with CLL have way too many lymphocytes. Hence a condition that is known as Lymphocytosis A positive test result means that the antibodies charged with attacking the Epstein-Barr virus were detected in your blood and that you most likely carry the virus. If your doctor determines you..
Because leukemia can also cause low platelet count, easy bleeding is often a sign. 6. Losing weight without trying. Low monocytes in a blood test result may be accompanied by unexplained weight loss. This is also often a symptom of leukemia, and doctors will need to perform additional tests to find the cause of low mono count along with weight. These antibodies can be detected by rapid agglutination assays, but false-positive results have occasionally been reported for several conditions, including leukemia, rubella, malaria, systemic lupus erythematosus, pancreatic carcinoma, viral hepatitis, and human immunodeficiency virus infection (1 - 3)
Other causes of false-positive monospots include malaria, autoimmune hepatitis, systemic lupus erythematosus, leukemia, pancreatic cancer, or, rarely, primary HIV infection (Am. J. Med. 2001;111:192-4). Of course, primary HIV is far less common than EBV, but should be kept in mind The mononucleosis spot test looks for 2 antibodies in the blood. These antibodies appear during or after an infection with the virus that causes mononucleosis, or mono. How the Test is Performed A blood sample is needed A positive mono test with an increased number of white blood cells and reactive lymphocytes on a blood smear in the presence of symptoms associated with mono indicates a likely diagnosis of infectious mononucleosis. A negative mono test requires careful interpretation ..
Leukemia starts in the bone marrow, so checking the bone marrow for leukemia cells is a key part of testing for it. Bone marrow aspiration and biopsy: Bone marrow samples are obtained by bone marrow aspiration and biopsy - tests usually done at the same time. The samples are usually taken from the back of the pelvic (hip) bone, although in. . These are most often a sign of mononucleosis. Your provider will also consider other blood test results and your symptoms. A small number of people with mononucleosis may never have a positive test
Very nice comment, my younger brother had mono a year ago because of EBV and one od hospital declared to me that he is having 99% ALL as the bosy symptoms are same for both. Then we tried in another hospital n they did smear test before bone marrow biopsy and found EBV and he was fine within 10 days If a doctor uses a monospot test, it can be falsely positive when the patient has conditions that include hepatitis, leukemia, lymphoma, rubella, systemic lupus erythematosus, and toxoplasmosis. The doctor must use the patient's symptoms and other tests to distinguish between these conditions. How Mononucleosis Is Treated Was this page helpful A monospot test can be administered using a finger-prick blood test in order to determine whether or not a patient has mono, but according to my own experience, this test is not 100% accurate. Even given my encounter with the false positive reading though, I'd still want the benefit of the test the next time around
One must consider that the heterophile antibody test results may be negative early in the course of EBV infectious mononucleosis. Positivity increases during the first 6 weeks of the illness. In patients with a compatible syndrome and negative heterophile antibodies, the test can be repeated if the patient is early in their clinical course Positive monospot tests preceding the diagnosis of acute monocytic leukemia in two adolescents. Miale TD, Barbosa JL, Dellinger CT, Wolfson SL. The early detection and treatment of two cases of acute monocytic leukemia (AMoL) was hampered by the presence of positive slide tests for infectious mononucleosis (IM) TO OUR knowledge, 26 cases 1-15 have been reported of the association of infectious mononucleosis and acute leukemia (Table). In seven instances, the former preceded the latter by one to 36 months, in 16 cases the acute leukemia preceded the infectious mononucleosis by one to 45 months, and in three patients both diseases were diagnosed simultaneously A positive test in the presence of consistent clinical and/or hematologic findings confirms the diagnosis of infectious mononucleosis. Approximately 10% of mononucleosis syndromes are heterophil-negative. In some of these, antibody to specific Epstein-Barr viral antigen can be demonstrated. Others may be due to CMV, HSV, or toxoplasmosis The complete blood count is the most common blood test ordered when dealing with a case of leukemia. The primary aim of the test is to be able to measure the concentration of white blood cells, platelets and red blood cells in the blood. Just as with any other type of blood test, a small sample of blood will be drawn from the patient
My field the lab tech looking at your slide because the automated machine says something is not normal, get's the first look at your CBC. (cellular blood. Leukemia and Lymphoma Community 1.85k Members Strong positive mono test in 5 year old Ingrid3. Hello, My son is 5 and has been sick with flu-like symptoms so I took him to his ped. and he tested for strep, mono and tried to complete a CBC test. The strep came back negative but the mono came back positive A positive monospot test result occurs when blood clumps form, indicating the presence of heterophil antibodies. This means that you probably have got mononucleosis but it is still not definite. A positive result may also be caused by diseases such as leukemia, lymphoma, hepatitis, rubella, lupus and rheumatoid arthritis If you do not have any symptoms, then the test could be a false positive. This can happen in case of erroneous sampling, toxoplasmosis, rubella, leukemia and lymphoma etc. Hope this helps. Please do leave a positive rating for the service.

Pulmonary function test; Lab tests: These tests measure the amount of red blood cells, white blood cells and platelets in the blood, which are often lower than normal when leukemia has developed. Lumbar puncture: Also known as a spinal tap, this test may be required to determine the extent of leukemia. Lumbar punctures may also be used to. . To confirm the diagnosis and identify the specific type of leukemia, a needle biopsy and aspiration of bone marrow from..
Studies have shown that the Monospot test can lead to false negative and false positive results. One must consider that the heterophile antibody test results may be negative early in the course of.. Progressive hepa tosplenomegaly and generalized lymphadenopathy developed but the mono spot test, more strongly positive PaulBunnell tests, numerous atypical lymphocytes, and lack of anemia or thrombocytopenia con- tinued to support the diagnosis of I M (Table 1) Leukemia is cancer of the blood and bone marrow.Bone marrow, located in the spongy portions of the body's bones (primarily ribs, vertebrae, sternum, bones of pelvis), makes early blood-forming cells, precursors of red blood cells, platelets, and white blood cells. These immature blood cell precursors grow and mature in the bone marrow until being released into the bloodstream Features of chronic myelomonocytic leukemia People with CMML may have shortages of some blood cells, but a main problem is too many monocytes. (at least 1,000 per mm 3). Often, the monocyte count is much higher, causing their total white blood cell count to become very high as well
Would a negative mono test show signs of Leukemia? Any experts or someone willing to give a few suggestions?

I am not a doctor or an expert but I do believe one of the ways they have an indicator someone has Luekemia is by an. A positive monospot blood test generally means that someone has an active case of infectious mononucleosis. This is a rapid test that will generally produce same day results. There are no specific guidelines to follow for the general population, although a doctor may order instructions for the test based on a specific medical history
Monospot positive at week 1 in 25% of patients Heterophile Antibodies are typically formed by 1 week of symptom onset But typically titers are too low for detection at this time Monospot positive by week 3 in >90% of patient proven infectious mononucleosis. False-positivereactions tothe Mono-spot test have been reported in in¬ fectious hepatitis,' acute leukemia,-and lymphoma. The purpose of this report is to describe two patients with pancreatic carcinoma with ob¬ structive jaundice who had positive Monospot tests early in their illness. Report of Cases Case 1. toms. It should be noted that if the heterophile antibody test is positive, it can remain so for up to a year before the antibodies decline. Also, false positive tests are rare but can be caused by some malignancies (lymphoma and leukemia), infections (HIV, HSV, toxoplasmosis, rubella), and autoimmune disor False-positive results may occur in the presence of narcotic addiction, serum sickness, lymphomas, hepatitis, leukemia, cancer of the pancreas, and phenytoin therapy. A false-negative result may occur if treatment was begun before antibodies developed or if the test was done less than 6 days after exposure to the virus
Mono tests are done to find antibodies which would indicate the presence of the Epstein-Barr virus in the blood. A quick screening test that is often done to confirm a diagnosis of mononucleosis is the monospot test that detects the heterophil antibody, which forms during some types of infections Less than 2% false positives have been reported with Hodgkin's disease, lymphoma, acute lymphocytic leukemia, infectious hepatitis and pancreatic carcinoma. The simultaneous occurrence of infectious mononucleosis and hepatitis has been reported Glandular fever is likely if the monospot test is positive or the FBC has more than 20% atypical or 'reactive' lymphocytes, or more than 10% atypical lymphocytes and the lymphocyte count is more than 50% of the total white cell count
The early detection and treatment of two cases of acute monocytic leukemia (AMoL) was hampered by the presence of positive slide tests for infectious mononucleosis (IM). This assumes great importance with the recent development of specific therapy, effective for certain subtypes of nonlymphocytic leukemia . Mononucleosis tests are blood tests to look for antibodies that indicate mononucleosis (mono), which is usually caused by the Epstein-Barr virus (EBV).The antibodies are made by the immune system to fight an infection.. Mono tests include: Monospot test (heterophil test) Sixty untreated patients with B- chronic lymphoid leukemia were enrolled. Complete blood count, direct Coombs test, serum urea, creatinine, uric acid and LDH levels were determined. Data were compiled and analyzed using SPSS version 21. Results: Out of 60 patients, 42(70%) were males and 18(30%) were females. Mean age was 59±9.2 years A 17-year-old female with suspected mononucleosis tested negative for heterophile antibody using the slide agglutination monotest. Her serum was sent to a reference laboratory, and the following results were obtained: negative for IgM anti-VCA, positive for antibody to EA-D. What do these results suggest Leukemia is a very serious form of cancer that affects the blood. It is a difficult cancer to treat due to the fact that it is in the blood. Mono is simply a viral infection that the body will create antibodies to fight. Mono is much less serious than Leukemia
Showing 1 - 20 of 48 for mono and leukemia. (0.013 seconds) Are false negatives common with leukemia tests? Nov 29, 2011 There are things that can cause false positive mono test results, but you describe the typical symptoms of mono, with low grade fever, sore throat and fatigue, and elevated liver enzymes. (8 replies Reactive lesions such as Kikuchi lymphadenitis, infectious mononucleosis, autoimmune lymphoproliferative syndrome, and immunoglobulin G4-related sclerosing disease can be misdiagnosed as lymphomas. Anaplastic large-cell lymphoma variants that are positive for anaplastic lymphoma kinase, classical Hodgkin's lymphoma variants, and infarcted. Reactive heterophile antibodies in a patient with the typical symptoms are diagnostic of EBV and further testing for specific antibodies to EBV is not necessary. Studies have shown that the.. Diagnosis Physical exam. Your doctor may suspect mononucleosis based on your signs and symptoms, how long they've lasted, and a physical exam. He or she will look for signs such as swollen lymph nodes, tonsils, liver or spleen, and consider how these signs relate to the symptoms you describe
Blood tests can distinguish between the type of white cell seen in leukemia and that with mono. The mono spot test identifies an antibody which is present in mononucleosis and is the test most commonly used to tell whether someone has mono or some other ailment. This test may not become positive until one has had symptoms for 5-14 days and may. A mononucleosis spot is a test involving blood screening and is also known as the Paul-Bunnell test, Heterophile agglutination test, Heterophile antibody test or simply the mono spot test. This test is aimed at finding two antibodies that are present in blood both during and after being infected with the EBV virus that causes mono A positive ANA test in patients with Raynaud's phenomenon increases the risk of developing a systemic rheumatologic disease from 19% to 30%, whereas a negative test decreases that chance from 19. The enzyme-linked immunosorbent assay blood test shows whether your furry friends have the FeLV proteins in their blood, according to WebMD. This test, which is performed by your veterinarian, can also be used on the kittens once they reach around 6 to 8 weeks of age and are big enough to obtain a sample from, according to Cat Channel A positive test means heterophile antibodies are present. These are most often a sign of mononucleosis. Your provider will also consider other blood test results and your symptoms. A small number of people with mononucleosis may never have a positive test. The highest number of antibodies occurs 2 to 5 weeks after mono begins
The mononuclear spot test or monospot test, a form of the heterophile antibody test, is a rapid test for infectious mononucleosis due to Epstein-Barr virus (EBV).It is an improvement on the Paul-Bunnell test. The test is specific for heterophile antibodies produced by the human immune system in response to EBV infection. Commercially available test kits are 70-92% sensitive and 96-100%. There are things that can cause false positive mono test results, but you describe the typical symptoms of mono, with low grade fever, sore throat and fatigue, and elevated liver enzymes. (8 replies Myeloproliferative neoplasms (MPNs) are a group of blood cancers that cause excess blood cell production in the bone marrow and often in the peripheral blood, and are characterized by clonal genetic changes. MPNs include chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF), chronic neutrophilic leukemia (CNL), and chronic. Feline leukemia virus (FeLV) and feline immuno deficiency virus (FIV) are among the most common causes of infectious disease of cats and are found worldwide.

The monotest is a quick test for diagnosing mononucleosis, a infectious disease caused by the Epstein Barr virus (EBV). A positive monotest, in the presence of typical symptoms such as fever, loss of appetite and swollen lymph nodes, it is highly indicative of the presence of mononucleosis.. Monotest. The Monotest is a test for the mononucleosis, used to quickly and sufficiently reliably. Many times it is difficult to differentiate between mono and leukemia based on the symptoms alone. So we order tests. In leukemia peripheral blood film shows blasts along with other lymphocytes, which are not seen in your daughter's case so doctors ruled out that But in the setting of, say, leukemia, the white could itself would also be very high. Ask Your Own Health Question. Customer reply replied 8 years ago. basically overall the because I showed symptoms of mono, my mono test came up positive then I should not web be thinking about cancer correct? I just over think, my bloodwork is usually always. This test is done to diagnose an infection, anemia, or leukemia. It may also be used to monitor one of these conditions, or to see if treatment is working Lab tests are the second part of a doctor's diagnosis. One of the most reliable ways to diagnose mononucleosis is the monospot test (or heterophile test). This blood test looks for antibodies..
The mono test is used to help determine whether a person with symptoms of mon has infectious mononucleosis. It is frequently ordered along with a CBC (complete blood count). The CBC is used to determine whether the number of white blood cells (WBCs) is elevated and whether a significant number of reactive lymphocytes are present. A strep test may also be ordered with the mono test to determine. In the majority of children and in more than one-half of adults with Ph1-positive ALL, the molecular abnormality is different from that in Ph1-positive chronic myelogenous leukemia (CML). Many patients who have molecular evidence of the BCR-ABL fusion gene, which characterizes the Ph1, have no evidence of the abnormal chromosome by cytogenetics A small percentage of people with clinical signs of CML do not have cytogenetically detectable Ph chromosome, but they almost always test positive for the BCR-ABL1 fusion gene on chromosome 22 with other types of tests. FISH (Fluorescence In Situ Hybridization). FISH is a laboratory test used to examine genes and chromosomes in cells Epstein-Barr virus (EBV) is a highly prevalent virus, transmitted via saliva, which often causes asymptomatic infection in children but frequently results in infectious mononucleosis in adolescents.

test code 26355 (or add-on test code 263551 when ordered with a CBC/chemistry profile), is recommended as a confirmatory and staging test following an in-clinic screening FeLV antigen test. The stand-alone FeLV Quant RealPCR Test, test code 26354, may be used following a positive FeLV Antigen by ELISA or for monitoring progression over time One is a false positive ELISA test and the other is a stage of the disease is present at which the IFA test doesn't detect infection. Therefore the suspect cat or kitten should be isolated and retested in at least 6 weeks. If, at that time the cat is IFA positive, you know that the cat if infected. The IFA is 99% accurate Also, the doctor will conduct a physical exam to check out the lymph nodes and other affected areas. Next, doctors may look for further evidence of leukemia through a blood test, bone marrow test, gene test, lymph node biopsy, or imaging tests. Treatment of leukemia will depend on the type and stage of the cancer.

Monospot tests are usually positive in approximately 85% of patients with infectious mononucleosis. Positive test results will not occur until 1Â - 2 weeks into the illness NOTE: A positive test result may be read as soon as a distinct pink-purple colored band appears at the Test position (T) and at the Control position (C). Any shade of pink-purple colored horizontal band at the Test position (T) should be reported as a positive result Yes, give it time: The acute symptoms of infectious mononucleosis (mono), such as fever, sore throat, and enlarged lymph nodes, typically last 2-3 weeks. Fatigue may last longer, but most people feel entirely well after 1-2 months. Once in a while, tiredness etc may last 6 months If you test positive for leukemia, your doctor will perform a biopsy of your bone marrow to determine which type you have. Treatment depends on your age, general health, and type of leukemia. You might receive a combination of treatments that could include chemotherapy, biological therapy, radiation therapy, and stem cell transplantation
ON THIS PAGE: You will find a list of the common tests, procedures, and scans that doctors can use to find out what's wrong and identify the cause of the problem. Use the menu to see other pages.Doctors use many tests to find, or diagnose leukemia. They also do tests to find out the subtype (see Subtypes). Doctors may also do tests to learn which treatments could work best Mononucleosis tests are blood tests to look for antibodies that indicate mononucleosis (mono), which is usually caused by the Epstein-Barr virus (EBV). The antibodies are made by the immune system to fight an infection A positive result of a heterophile antibody test also is strong evidence in favor of a diagnosis of infectious mononucleosis. A negative result of an antibody test, particularly during the first.. Mononucleosis (mono) is a contagious infection caused by a herpes virus called Epstein-Barr. Other viruses can also cause mono. The infection is common among teenagers and young adults. People with mono experience extreme fatigue, fever and body aches.

The diagnosis was based on immunophenotyping by flow cytometry (positive for CD34, CD4, CD11b and CD90 and negative for MHCII) and cytochemical staining (positive for ALP and ANBE): A: Myeloid blasts with cells differentiating towards monocytes (promonocytes due to their high nuclear to.
The mono test is 71% to 90% accurate and may be used as an initial test for diagnosing infectious mononucleosis. However, the test does have a 25% false-negative rate due to the fact that some people infected with EBV do not produce the heterophile antibodies that the mono test is designed to detect. What does a positive Monospot test mean? A. They checked her blood , full CBC and mono test, which came back negative. She is 17 years old, they feel that it is swollen because of a viral infection. My concern is she still is in lots of pain AND her sister, now 19 had acute myeloid leukemia at 11. I am very concerned as I looked on the internet and this can be a cause of leukemia
Color Slide® II Mononucleosis Test has been adjusted to provide a positive test approximating the sensitivity of a guinea pig kidney absorbed Davidsohn sheep cell titer of 1:28 to 1:56. Therefore, a semiquantitative result can be approximated by multiplying the reciprocal of the highest dilution in which agglutination occurs (end point) by 28 Infectious mononucleosis, mono, kissing disease, and glandular fever are all terms popularly used for the very common infection typically caused by the Epstein-Barr virus (EBV), but other viruses can also cause the disease. This article focuses specifically on the Epstein-Barr virus as a cause of mono since this is the characteristic virus associated with the condition White blood cells make up our defense against foreign organisms and inner diseases, including autoimmune disease and cancer. They are produced by the bone marrow and have a lifespan of a few weeks. White blood cell count is flexible, and although it has a normal range of 4000-11000 per cubic milliliter, they can change their numbers and increase in response to infections, allergy or cancers
• Usually have a positive skin test reaction or positive TB blood test (see pages 6-7) • May develop TB disease if they do not receive treatment for latent TB infection (see page 8) Many people who have latent TB infection never develop TB disease. In these people, the TB bacteria remain inactive for a lifetime without causing disease Infectious mononucleosis is characterized by swollen lymph glands, fever, sore throat, and extreme fatigue Mononucleosis usually lasts for 1 to 2 months. Symptoms may include fever, swollen lymph glands in the neck, armpits, and groin, constant fatigue, sore throat, enlarged spleen, and jaundice, a yellow discoloration of the skin A positive result in the IM screening test, together with symptoms of mononucleosis, is the basis for a diagnosis of infectious mononucleosis. In addition to a positive reaction on the IM screening test, an infected person generally has an increased white blood cell count, with a higher than usual number of lymphocytes which may appear reactive Some may require as long as 3 months. Fifty percent of children under 4 years may remain heterophile negative. The intramuscular heterophile antibody may be positive in leukemia, cytomegalovirus, Burkitt's lymphoma, rheumatoid arthritis, viral hepatitis, and Toxoplasma gondii. Epstein-Barr virus specific laboratory testing may be helpful in. Mononucleosis (Blood) Does this test have other names? Mono test, monospot test, Epstein-Barr antibody test . What is this test? This test looks for signs in your blood that you have the Epstein-Barr virus. The Epstein-Barr virus (EBV) is a common virus that's part of the herpes virus family. It causes infectious mononucleosis, or mono
A positive result means that your bones are breaking down for some reason. If you have other tests that show you have hairy cell leukemia, it will help confirm the diagnosis. If you have a positive result but not hairy cell leukemia, you may have other tests to confirm another cancer or another cause, such as osteoporosis Acute lymphoblastic leukemia (ALL) is an aggressive type of leukemia of either B- or T-lineage immature lymphoid cells. ALL is primarily a childhood disease (ALL represents 75-80% of all acute leukemias in children ) and follows a bimodal distribution; the first peak occurs between 3 and 5 years of age and the second in adults older than 50 years.. Mono not specific: Monospot is not specific for EBV infection and may be positive due to other viral infections. Even if it is mono, there is no specific treatment for it and you need to wait out for the symptoms to subside. If you are want to be sure, repeat the EBV antibody test in two weeks Description: Mononucleosis Qualitative Blood Test. This test is used to aid in the diagnosis of Infectious Mononucleosis (Mono).Mononucleosis is an infection caused by Epstein Barr Virus (EBV).This test looks for Heterophile Antibodies which the immune system produces in response to an infection. EBV is spread through the saliva and nearly 95% of people will be exposed by age 40 A small number of people with mononucleosis may never have a positive test. The highest number of antibodies occurs two to five weeks after mono begins. They may be present for up to one year. In rare cases, the test is positive even though you do not have mono. This is called a false-positive result, and it may occur in people with: Hepatiti
This suggests the presence of a monoclonal, lambda-positive (= a lambda-monoclonal) B-cell population which may be leukemia or lymphoma cells. The figures shown so far were only schematic. In reality the histograms generated after flow cytometric measurement look different What Are the Symptoms of Leukemia? Many types of leukemia produce no obvious symptoms in the early stages. Eventually, symptoms may include any of the following: Anemia and related symptoms, such. About 95% of adults with CML have leukemia cells with the Ph chromosome. When the Ph chromosome is present, CML is described as Ph-positive, or Ph+, CML. When the Ph chromosome isn't present, it is described as Ph-negative, or Ph-, CML. People with Ph+ CML have a more favourable prognosis than those with Ph- CML. Other chromosome change Patients with clinical infectious mononucleosis demonstrated 8-10% pyknotic lymphocytes in 24 and 48 hour samples in all three anticoagulants (see Figure 1) compared with controls, other diseases and lymphoproliferative disorders . An unexpected predictive correlation of pyknotic cells with positive monospot or Epstein-Barr Virus.
