Clinical significance: |
The Zika Virus Antibody (IgM) assay is intended for the qualitative detection of Zika virus IgM antibodies in human sera collected from individuals meeting CDC Zika virus clinical criteria and/or CDC Zika virus epidemiological criteria: The Zika Virus Antibody (IgM) assay results are for the presumptive detection of IgM antibodies to Zika virus (ZIKV). Reactive results are not definitive for diagnosis of Zika virus infection. False positive results are possible in patients with a history of infection with other Flaviviruses. Confirmation of the presence of anti-Zika IgM antibodies requires additional testing according to the latest CDC testing algorithms for the diagnosis of Zika virus infection. Within the United States and its territories, presumptive positive Zika test results are reported, as required, to the appropriate public health authorities. Results of the Zika Virus Antibody (IgM) test cannot be used as the sole basis of patient management decisions and must be combined with clinical observations, patient history, epidemiological information, and other laboratory evidences. Zika IgM levels over the course of illness are not well characterized. Negative results do not preclude the possibility of Zika virus infection, past or present. Negative results may be seen in specimens collected before detectable levels of IgM antibody develop or after the window of detectable IgM is present. | |
