Overview
Blood serum and plasma testing is conducted to detect viral nucleic acids or virus specific IgM. Laboratory testing is the primary source when differentiating between Zika and other commonly misdiagnosed viruses.[1]
Laboratory Findings
- During the first week after onset of symptoms, Zika virus can often be diagnosed by performing reverse transcriptase-polymerase chain reaction (RT-PCR) on serum.
- Virus-specific IgM and neutralizing antibodies typically develop toward the end of the first week of illness.
- Cross-reaction with related flaviviruses (e.g., dengue and West Nile viruses) is common and may be difficult to discern.
- Plaque-reduction neutralization testing can be performed to measure virus-specific neutralizing antibodies and discriminate between cross-reacting antibodies in primary flavivirus infections.[2]
