Question:My rubella IgG test is positive. Its value is 214.6 IU/ml. Doctor has asked for rubella IgG avidity test. Is all OK.
Answer: hi dear!
Avidity is the strength of binding of antibodies to antigen. When a patient's immune system is challenged with an antigen, in this case rubella virus, the first response is the production of IgM antibodies. The rubella IgG avidity assay is particularly useful for confirming acute rubella infections in pregnant women.
Answer: Hello dear. A positive rubella IgG test result is good—it means that you are immune to rubella and cannot get the infection. This is the most common rubella testdone. Negative: Less than 7 IU/mL IgG antibodies and less than 0.9 IgM antibodies. Hope it helps.
