Ordering Recommendation

May be used to diagnose chikungunya viral infection during acute phase of disease (>5 days after symptom onset). In endemic regions, recommend co-testing for dengue and Zika virus because clinical picture of these diseases is similar. If exact date of onset is known, consider co-testing with Chikungunya by PCR (2013085).
