Clinical Utility

The ZIKV Detect™ IgM Capture ELISA is intended for the presumptive detection of Zika virus IgM antibodies in human sera collected from individuals meeting CDC Zika virus clinical criteria (e.g., a history of clinical signs and symptoms associated with Zika virus infection) and/or CDC Zika virus epidemiological criteria (e.g., history of residence in or travel to a geographic region with active Zika transmission at the time of travel, or other epidemiological criteria for which Zika virus testing may be indicated). The assay is intended for use in laboratories in the United States that are certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, to perform high complexity tests, or by similarly qualified non-U.S. laboratories, consistent with the latest CDC guideline for the diagnosis of Zika virus infection.


The ZIKV Detect™ IgM Capture ELISA is an enzyme linked capture immunoassay for the detection of human IgM antibodies targeting the ZIKV envelope glycoproteins. The ZIKV Detect™ IgM Capture ELISA has been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.


False positive results are possible in patients with a history of infection with other Flaviviruses (Dengue, West Nile, Japanese Encephalitis, and Saint Louis encephalitis (SLE)) . Confirmation of the presence of anti-Zika IgM antibodies in presumptive positive specimens requires additional testing according to the latest CDC guideline for the diagnosis of Zika virus infection.

Note: In the case of specimens originating from regions with a known West Nile virus outbreak, an FDA-cleared West Nile virus IgM assay should be run in parallel with the ZIKV Detect™ IgM Capture ELISA.

2-5 days from receipt of specimen.

Specimen Type Order Code CPT Code NY Approved Volume Assay Range Special Instructions
Serum 30294 86794 Yes

2 mL (min. 0.5 mL)

Presumptive Zika Positive: Presence of detectable Zika IgM antibody, possible recent infection with ZIKV. The result should be confirmed by the latest CDC guideline for the diagnosis of Zika virus infection.

Possible Zika Positive: Specimens that fall in this category may still have levels of Zika IgM antibody present in serum and follow-up testing is required; however, other confounding IgM antibodies from related flaviviruses may be present that cause this level of reactivity.

Presumptive Other Flavivirus Positive: The result should be confirmed with FDA-cleared Dengue and West Nile virus IgM devices.

Negative: Negative results do not preclude the possibility of Zika virus infection, past or present. Negative results may be seen in specimens collected before day four post onset of symptoms or after the window of detectable IgM closes.
