About the test
IgG avidity shows the strength with which antibodies bind to Epstein–Barr virus antigens. It is used as an additional characteristic of the immune response. The test may help clarify the timing of first contact in certain ambiguous serological situations, where this is supported by the method used.
The conclusion depends on the specific antigen used to measure avidity, the test system and the other EBV antibodies. A single index does not date infection precisely or prove reactivation. The antigen and test format should be clarified with the laboratory before ordering.
Why it is ordered
- Complement the evaluation of ambiguous EBV antibody results.
- Clarify the characteristics of IgG within the laboratory algorithm.
How to prepare
Before taking the test, ask the laboratory about preparation and specimen collection requirements. Tell your doctor about medicines and recent treatment. Do not stop prescribed medicines on your own.
