Detects IgG antibodies to cytomegalovirus — establishes whether you have ever been infected. IgG antibodies to cytomegalovirus (CMV) reflect past infection and lasting immune memory. Because CMV stays in the body for life after a first infection, a positive IgG means exposure at some point in the past and does not indicate current illness. A negative IgG is equally informative: it identifies people who have never encountered CMV and are therefore susceptible to a first (primary) infection, which is the scenario that carries risk in pregnancy and around transplant. CMV IgG is the natural companion to CMV IgM — the two together distinguish never-infected from previously infected from possibly recently infected, which no single antibody can do alone. **Clinical use:** STI and infectious disease testing identifies current or past infections that often present without obvious symptoms — preventing complications, transmission, and long-term sequelae. ## Who should order it? Anyone with a new sexual partner, symptoms suggesting an STI, recent exposure, planning pregnancy, or seeking routine sexual health screening per CDC recommendations. ## Biomarkers measured - Cytomegalovirus (CMV) Ab, IgG ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $59.99 | $65.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $40.99 | $46.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
