Epstein-Barr virus EBV , a member of the herpesvirus group, is the etiologic agent of infectious mononucleosis. EBV infections are difficult to diagnose in the laboratory since the virus does not grow in standard cell cultures. Most of these heterophile antibody-negative cases of infectious mononucleosis-like infections are due to cytomegalovirus, but in a series of 43 cases, EBV was the cause in 7.
Infection with EBV usually occurs early in life. For several weeks to months after acute onset of the infection, it is spread by upper respiratory secretions that contain the virus. Among the clinical disorders due to EBV infection, infectious mononucleosis is the most common. Other disorders due to EBV infection have been recognized for several years, including African-type Burkitt lymphoma and nasopharyngeal carcinoma.
Acceptable: Red top. Specimen Volume: 1 mL. If not ordering electronically, complete, print, and send a Microbiology Test Request T with the specimen. Epstein-Barr virus EBV , a member of the herpesvirus group, is the etiologic agent of infectious mononucleosis. EBV infections are difficult to diagnose in the laboratory since the virus does not grow in standard cell cultures.
Heterophile antibodies usually appear within the first 3 weeks of illness but decline rapidly within a few weeks. Most of these heterophile antibody negative cases of infectious mononucleosis-like infections are due to cytomegalovirus, but in one series of 43 cases, EBV was the cause in 7. Infection with EBV usually occurs early in life. For several weeks to months after acute onset of the infection, it is spread by upper respiratory secretions that contain the virus.
Among the clinical disorders due to EBV infection, infectious mononucleosis is the most common. EBV infection may also cause lymphoproliferative syndromes, especially in patients with AIDS and in patients who have undergone renal or bone marrow transplantation. Using immunofluorescent staining techniques, 2 patterns of EA are seen, 1 diffuse staining of both cytoplasm and nucleus early antigen-diffuse: EA-D and 2 cytoplasmic or early antigen restricted EA-R. Antibodies responsible for the diffuse staining pattern EA-D are seen in infectious mononucleosis and NPC, and are measured in this assay.
Reference values apply to all ages. Generally, this antibody can only be detected during active Epstein-Barr virus EBV infection, such as in patients with infectious mononucleosis.
Although this level of specificity is useful for diagnostic purposes, the false-positive rate indicates that the test is not useful for NPC screening. This test detects the diffuse components of early antigen only. Fields Virology. Lippincott Williams and Wilkins; Lennette ET: Epstein-Barr virus. Her doctor didn't know how to interpret her results and dismissed her concerns. What Emily experienced is very common.
Conventional doctors often are hesitant to test for EBV and don't truly know how to read the results. What is the real message from Epstein-Barr antibodies? EBV stands for Epstein-Barr virus. Epstein-Barr virus is a virus that typically causes a mild to moderate illness. The virus usually does not cause any symptoms in children. Just had blood work done and epstein barr vca igg ab was Doctor's Assistant: In general, how has your health been lately? Very fatigue, chills and upper center back pain,neck pain.
Doctor's Assistant: Anything else in your medical history you think the doctor should know? I have rheumatoid arthr and had thyroid cancer about 10 yrs ago and recently my blood Should I be concerned if my EBV titers are very high Christine Hom answered. Pediatrics 30 years experience. No: Having high EBV titers demonstrates a good immune response - measures antibody levels. Ankush Bansal agrees. My result was given as over The range is less than 18 is negative.
Over 22 is positive. High and low values Lab results VCA stands for Viral capsid antigen. Epstein-Barr virus EBV is known to be important in pulmonary fibrosis. Sputum samples were collected from patients both during exacerbations of COPD and when stable. If the bothersome symptoms continue on past this time, then there may be other health issues that may need to be addressed. The Epstein Barr blood test can help to confirm this if necessary so that a new treatment plan can be developed.
Resolution of the illness may occur before the diagnostic antibody levels appear. Useful Blogs. Video Result.
