Rubella Virus Avidity near me in Dehradun

The Rubella Virus Avidity test measures the binding strength, or avidity, of rubella-specific IgG antibodies present in the blood. The level of avidity helps determine whether an infection is recent or occurred in the past. Low-avidity IgG antibodies suggest a recent rubella infection, usually within the last few months, while high-avidity IgG antibodies indicate past infection or immunity acquired through vaccination. By assessing the maturity of these antibodies, the test helps distinguish between a primary infection and long-standing immunity. This information is especially important in pregnant women, as a recent infection may pose serious risks to the developing baby, including congenital rubella syndrome.
