Test Code VZIKM Zika Virus, IgM Antibody Capture ELISA, Serum


Ordering Guidance


For specimens collected less than 14 days post-symptom onset or possible Zika virus exposure, reverse transcription polymerase chain reaction testing for Zika virus using serum and urine is recommended to exclude a false-negative Zika virus IgM result. For more information see VZIKU / Zika Virus, PCR, Urine and VZIKS / Zika Virus, PCR, Serum.



Additional Testing Requirements


This is a screening test for Zika virus. As required by your local health department, confirmatory testing of a presumptive positive result may be necessary.

 

Due to similar clinical presentation and cross reactivity, testing for IgM-class antibodies to dengue virus is recommended to occur concurrently with Zika virus IgM testing. Order DENVP / Dengue Virus Antibody/Antigen Panel, Serum.
