Comments about the test interpretation (e.g. clinical implication of test results)

The analyzer automatically calculates SARS-CoV-2 IgM antibody concentrations expressed as an Index value and grades the results. Assay range: 0 – no limit. Negative result - A result below the 1.1 Index may indicate the absence or level of IgM antibodies to SARS-CoV-2 below the threshold. The test could score negative in patients during the incubation period and in the early stages of infection. Positive result - A result above or equal to the 1.1 Index generally indicates the presence of IgM antibodies to SARS-CoV-2 and generally indicates exposure to SARS-CoV-2. Test results are reported qualitatively as positive or negative. However, diagnosis of SARS-CoV-2 infection should not be established on the basis of a single test result, but should be determined in conjunction with clinical findings, patient history, and always in association with medical judgment.
