Test Request Order Form must accompany the specimen to include the following information: symptoms and date of onset, pregnancy status, travel and vaccine history.


During the first 7 days of illness, viral RNA can often be identified in serum and RT-PCR is the preferred test. Therefore, to definitively rule out the diagnosis, convalescent-phase samples should be obtained from patient whose acute-phase samples test negative. Refer to Chikungunya Virus Antibody IgM test for specimen collection after 7 days.
