Description
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.
Collection Note: Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Specimens must be plainly marked as "acute" or "convalescent."
