Avidity HSV 2 IgG
The Avidity HSV 2 IgG test is an important tool in diagnosing and tracking HSV-2 infections. Early and precise diagnosis can greatly influence the success of treatment and the recovery process. At the IntroLab in Belgrade, our experienced team is committed to delivering top-quality services and guiding you through each stage of your health care.
What is HSV 2 IgG?
Herpes simplex virus type 2 (HSV-2) is a virus that commonly causes genital herpes but can also lead to oral herpes. HSV 2 IgG refers to specific antibodies that the immune system produces in response to an HSV-2 infection. The Avidity HSV 2 IgG test measures the “strength” of the bond between these antibodies and the HSV-2 virus.
Why is Avidity HSV 2 IgG measurement important?
Measuring the avidity of IgG antibodies helps differentiate between a primary infection and a past or recurring HSV-2 infection.
- High avidity levels generally indicate a past or recurrent infection.
- Low avidity levels point to a recent or primary infection.
When is this test necessary?
This test is advised when there is a suspicion of HSV-2 infection, especially if symptoms point to such an infection but standard HSV-2 test results are inconclusive or conflicting. This test is also valuable for monitoring treatment effectiveness and evaluating the immune system’s response to the infection. It is particularly beneficial for individuals with weakened immune systems or those at higher risk of severe complications from the infection.

Frequently asked questions
What does the HSV 2 IgG avidity test show?
The Avidity HSV 2 IgG test measures how strongly IgG antibodies bind to herpes simplex virus type 2, the cause of genital herpes. Based on this, a doctor can distinguish a primary, recent infection from one acquired earlier or a recurrent one. At IntroLab laboratory the test is done from a venous blood sample, costs 3,500 RSD, and the result is ready in 8 days. It is most useful when standard HSV-2 tests are inconclusive.
What does high or low HSV 2 IgG avidity mean?
High avidity of HSV 2 IgG antibodies usually indicates an earlier, past or recurrent infection, because antibodies bind more and more strongly to the virus over time. Low avidity suggests a recent or primary HSV-2 infection. Avidity alone does not establish a diagnosis; it is considered together with other HSV results and symptoms. The IntroLab laboratory avidity result should always be interpreted by a doctor.
Is there also an avidity test for HSV 1?
Yes, IntroLab laboratory also performs the HSV 1 IgG avidity test, for herpes simplex virus type 1, which most often causes cold sores around the mouth. Both avidity tests cost 3,500 RSD each, are done from venous blood, and the result is ready in 8 days. Which test is needed, or whether both are, depends on symptoms and previous HSV antibody results, so the choice is made by a doctor.
