CMV AVIDITY TEST

The CMV Avidity Test measures the strength (avidity) of maternal cytomegalovirus (CMV) IgG antibodies to help distinguish a recent primary infection from a past infection. By quantifying how tightly IgG antibodies bind to CMV antigens, the test provides an avidity index that, together with IgM/IgG results and clinical history, helps determine timing of infection — a critical factor for pregnancy management.

This service is particularly relevant for expecting mothers in Dubai who have a positive or equivocal CMV IgM or new seroconversion. Rapid, lab-validated avidity results support obstetric decision-making (monitoring, ultrasound follow-up, or consideration of invasive testing) and allow timely counselling; interpretation should always be correlated with gestational age and prior serology by your clinician.
