Cytomegalovirus IgG Antibody
₹600.00
Description
- Definition: The Cytomegalovirus IgG Antibody test detects the presence of IgG antibodies specific to CMV in the blood. This indicates past exposure to the virus and helps determine immunity status.
- Purpose: This test is primarily used to diagnose previous CMV infections, assess immune response in patients at risk for complications (such as organ transplant recipients), and screen pregnant women for potential transmission risks to the fetus.
- Clinical Relevance: A positive IgG result suggests that a person has been infected with CMV at some point, providing immunity against future infections. This is particularly important in assessing the risk of congenital CMV in newborns and guiding management in immunocompromised individuals.
- Interpretation: A positive CMV IgG result indicates past infection, while a negative result suggests no prior exposure. However, the presence of IgG does not confirm an active infection; additional tests may be needed to assess acute infection status.
- Testing Method: The test requires a blood sample, which is analyzed in a laboratory using techniques such as enzyme-linked immunosorbent assay (ELISA) to detect CMV IgG antibodies. Results are typically available within a few days, helping to inform clinical decisions regarding patient management.
