    One source states that the specificity of the test is high, virtually 100%, [7] Another source states that a number of other conditions can cause false positives. [5] Rarely, however, a false positive heterophile antibody test may result from systemic lupus erythematosus, toxoplasmosis, rubella, lymphoma and leukemia.

    Heterophile antibodies can arise in non-EBV infections. False positive monospot tests may occur in cases of HIV, lymphoma, or systemic lupus erythematosus. Other assays for detection of EBV are available, including serologic markers. [7] An important clinical pearl for heterophile antibodies is they can also be seen in genetic immunodeficiencies.

    An example of helpful cross-reactivity is in heterophile antibody tests, which detect Epstein-Barr virus using antibodies with specificity for other antigens. Cross-reactivity is also a commonly evaluated parameter for the validation of immune and protein binding based assays such as ELISA and RIA .

    The false positive rate (FPR) is the proportion of all negatives that still yield positive test outcomes, i.e., the conditional probability of a positive test result given an event that was not present. The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate.
