To determine the utility of monospot testing in the diagnosis of mononucleosis in the collegiate student-athlete clinical setting.Retrospective cohort study.National Collegiate Athletic Association Division I sports medicine clinic.All varsity student athletes who had a monospot test and Epstein-Barr virus (EBV) titers obtained from January 1, 2016, through March 31, 2020, (n = 199) were included.Monospot, EBV antibody titers, and liver transaminase results.Using EBV titers indicating acute or recent infection as the gold standard for diagnosing infectious mononucleosis (IM), the reliability of a positive monospot test and elevated liver transaminases for the diagnosis of IM were examined.The monospot test had a sensitivity and specificity of 80.0% and 90.6%, respectively, with a positive predictive value of 36.4% and a negative predictive value of 98.5% in this cohort. All athletes diagnosed with IM also had elevated liver transaminases.The specificity of the monospot test is lower than previously reported in the literature, and a positive test is not sufficient to diagnose mononucleosis in this clinical setting. Positive monospot results should be confirmed with EBV antibody testing. Elevated transaminase levels are highly correlated with acute IM and could play a supporting role in the diagnosis.
