Both cytomegalovirus antibodies in one draw — IgG for past exposure and IgM for recent or reactivated infection. This orders both cytomegalovirus (CMV) antibody classes together from a single blood draw. The two answer different questions and are far more useful read side by side than alone: IgG shows whether you have ever been infected with CMV, while IgM rises within days to weeks of a new or reactivated infection and fades over the following months. Together they separate never-infected from previously infected from possibly recently infected — a distinction neither antibody can make on its own. This pairing is the standard starting point when CMV status matters, most commonly in pregnancy and around transplant. One caveat worth knowing: a positive IgM cannot by itself distinguish a true primary infection from a reactivation or a non-specific cross-reaction, and it can persist for months, so where the timing of a primary infection is clinically decisive an IgG avidity test is what dates it. **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 - Cytomegalovirus (CMV) Ab, IgM ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $109.99 | $115.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $74.99 | $80.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
