Catalog ID MZIKV Zika Virus IgM Antibody Capture MAC-ELISA, Serum

Important Note

Order: Ref Misc Referral Lab Test

Comment: Zika IgM

Useful For

Screening for the presence of IgM-class antibodies to Zika virus in patients presenting with symptoms for 14 or more days

 

Establishment of baseline serologic levels of IgM-class antibodies to Zika virus in women who have traveled to a Zika virus endemic region or who have had sexual exposure to Zika virus and who are considering conception


Advisory Information


This test is not intended for medical-legal use.

 

For specimens collected less than 14 days postsymptom onset or possible Zika virus exposure, the CDC recommends 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 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.
