Zika virus is an arthropod-borne flavivirus that has rapidly developed into a world-wide concern. Discovered in 1947, the virus was relatively obscure until an outbreak occurred in 2007 in the Yap islands and spread eventually to the Americas in 2015. Only 20% of patients infected with Zika virus develop symptoms. However, there can be serious consequences of infection including birth defects in developing fetuses and links to Guillain-Barré syndrome. The swift rise in infections has necessitated the development of diagnostic tests for both the detection of viral RNA and the presence of virus-specific antibodies. Abbott has developed a dual target RT-PCR assay for the detection of Zika virus RNA within serum, plasma, whole blood, and urine using the automated m2000 system for sample extraction to result reporting. The Abbott RealTime ZIKA assay has a limit of detection of 30 copies per mL in serum, 40 copies per mL in plasma and urine, and 120 copies per mL in whole blood and demonstrates high specificity against challenges from closely related infectious agents.
