What is a normal range for Epstein-Barr?
Optimal Result: 0 – 17.9 U/mL. EBV-VCA, IgG is an antibody (protein) that is produced by the body in an immune response to an Epstein-Barr virus antigen.
What does a high EBV IgG mean?
Primary infection. You may also have a primary infection if you have a high or rising level of anti-VCA IgG but no antibody to EBNA after 4 weeks of infection. In some rare cases, people with an active EBV infection don’t make antibodies to EBV antigens.
Will you always test positive for Epstein-Barr?
Since approximately 90% of us have EBV, testing positive isn’t significant unless you have EBV-like symptoms that can’t be explained by another cause. Your medical provider will sort that out with you. Click here to read what the Centers for Disease Control and Prevention says about EBV.
How is EBV viral load calculated?
To measure EBV loads, real-time polymerase chain reaction (PCR) is a standard and widely-used method (8, 11). The real-time PCR method measures the accumulation of amplified products with a laser scanning in a closed tube or 96-well plate format (12).
What is a high viral load for EBV?
For the 10 EBV-positive PTLD, EBV viral loads at the time of tumor presentation ranged from 16 to 8620 genome equivalents/100,000 leukocytes, with a median of 705 g.e. Only 2 of 10 patients had high values over 2500 g.e. at presentation whereas 3 of 10 had the lowest values (5-50 g.e.).
What is a high EBV DNA level?
The EBV DNA levels during follow-up were usually low (≤ 1000 copies/mL) and transiently detected in patients who remained disease-free, but high (> 1000 copies/mL) and detected on consecutive occasions in patients who had tumor recurrence.
Does Epstein Barr stay with you forever?
After you recover, EBV will remain dormant in your blood cells for the rest of your life. This means that your symptoms will go away, but the virus will stay in your body and can occasionally reactivate without causing symptoms.
How is EBV lymphoma diagnosed?
EBV is associated with a variety of lymphomas/leukemias, and epithelial malignancies, including nasopharyngeal carcinoma (NPC), lymphoepithelioma-like carcinoma, and gastric cancer (1). The diagnosis of EBV-associated malignancies is principally based on biopsy of the primary tumor.
