Back ground: The "gold standard" for diagnosing an MV infection in a lab is the presence of particular immunoglobulin M (IgM), which can be detected using either an ELISA (enzymelinked immunosorbent assay) or immunofluorescence. A most popular type of testing is serological because it is quick, affordable, and reliable and can be done in a high-throughput setting. According to earlier research comparing IgM tests, with RT-PCR-based assays as a reference, sensitivities ranged from 89.9 to 98.8% and specificities ranged from 92.5 to 97.9%.
