Test Code MZIKV Zika Virus IgM Antibody Capture ELISA, Serum
Secondary ID
65275Testing Algorithm
The following algorithms are available in Special Instructions:
-Assessment for Zika Virus Infection in Nonpregnant Individuals
Special Instructions
Method Name
IgM Antibody Capture Enzyme-Linked Immunosorbent Assay (MAC-ELISA)
Specimen Type
SerumAdvisory Information
If the patient is pregnant, order PNZIK / Prenatal Zika Virus IgM Antibody Capture-ELISA, Serum.
For specimens collected less than 14 days postsymptom onset or possible Zika virus exposure, the Centers for Disease Control and Prevention (CDC) recommends reverse transcription-polymerase chain reaction (RT-PCR) for ZIKV on serum and urine to exclude a false-negative Zika virus IgM result. These are available as RZIKU / Zika Virus, PCR, Molecular Detection, Random, Urine and RZIKS / Zika Virus, PCR, Molecular Detection, Serum.
Additional Testing Requirements
This is a screening test for Zika virus. A presumptive positive result requires confirmatory testing available from the Centers for Disease Control and Prevention (CDC) or a CDC-designated laboratory.
Due to similar clinical presentation and cross reactivity, testing for IgM-class antibodies to dengue virus, concurrently with Zika virus IgM testing, is recommended, order DENVP / Dengue Virus Antibody/Antigen Panel, Serum.
