Screens for infectious mononucleosis (mono) caused by the Epstein-Barr virus. The Monospot (heterophile antibody) test is a rapid screen for infectious mononucleosis, an illness caused by the Epstein-Barr virus (EBV). Mono commonly presents with extreme fatigue, sore throat, swollen lymph nodes, and fever — symptoms that overlap with strep throat and other infections. This test detects heterophile antibodies that appear during active EBV infection, helping to quickly confirm or rule out mono as the cause of symptoms. **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 - Heterophile Antibodies ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Labcorp | $84.99 | $90.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served.
