Chikungunya Antibodies, IgG and IgM
Ordering Recommendation
May aid in the diagnosis of chikungunya viral infection during acute phase of disease (>5 days after symptom onset). Testing should also be considered for other arthropod-borne viruses with similar symptomology based on clinical presentation and travel history.
