Zika Virus Antibody, IgM
Use
Presumptive qualitative detection of Zika virus IgM antibodies in human sera collected from individuals meeting CDC Zika virus clinical criteria (eg, a history of clinical signs and symptoms associated with Zika virus infection) and/or CDC Zika virus epidemiological criteria (eg, 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).
Special Instructions
Specimens from symptomatic patients or travelers from endemic regions should not be collected earlier than 8 days after symptom onset or exposure. Zika virus serologic testing is not recommended for asymptomatic pregnant women. Clinicians should refer to CDC guidelines before submitting specimens for testing.
Limitations
The test results may include false-negative and false-positive results. False negatives may occur if specimens are collected too early or too late relative to symptom onset, or if there are issues with specimen collection, storage, or transport. False positives can occur due to cross-reactivity with other flaviviruses like Dengue, or non-specific reactions. The assay has not been studied in pediatric populations and is not recommended for blood or plasma donor screening or general population screening.
