These cells are characterized by their increased size and often the presence of active protein synthesis. Your T cells and B cells work together. When the results are negative, these tests are better than heterophile antibody tests in ruling out infectious mononucleosis caused by EBV (negative likelihood ratio, 0.03 versus 0.14 to 0.18 for heterophile antibody tests), but when the results are positive, the tests are similar in their ability to rule in disease (positive likelihood ratio, 16 versus 9.7 to 28).16,17 VCA-IgG and VCA-IgM tests are useful in diagnosing patients who have highly suggestive clinical features but negative heterophile antibody test results.
