CMV Avidity

CMV Avidity test determines the binding strength between IgG antibodies and virus that can help distinguish a primary CMV infection from a past infection, particularly in pregnant women. CMV or cytomegalovirus is a common infection caused by a type of herpes virus. Many people do not know they have cytomegalovirus infection because it rarely causes problems in healthy people. However, it can cause serious complications in people with weak immune systems or in pregnant women. This test aids in the diagnosis of cytomegalovirus (CMV) infection during pregnancy after initial testing for CMV IgM and IgG is performed. Low CMV IgG avidity is an accurate indicator of primary infection within the last 3 to 4 months, while high avidity excludes primary infection within the last 3 months.
