Test ID: CHIKS Chikungunya Virus, PCR, Molecular Detection, Serum


Additional Testing Requirements


Due to the short period in which chikungunya RNA may be detected in serum, testing serum for IgM- and IgG-class antibodies to chikungunya virus is also recommended. See CHIKV / Chikungunya IgM and IgG, Antibody, Serum.

 

Testing for RNA or IgM-class antibodies to dengue and Zika viruses, concurrently with chikungunya virus testing should also be considered, given the overlapping clinical syndromes seen with these viruses.

Clinical Information

Chikungunya virus (CHIK) is an RNA virus of the genus Alphavirus, family Togaviridae, and is transmitted mainly through the bite of infected mosquitoes in the genus Aedes (A aegypti and A albopictus). This is the same mosquito that transmits dengue, yellow fever, and Zika viruses. Most people infected with chikungunya virus will develop some symptoms, most commonly fever and joint pain. There is no specific antiviral treatment for chikungunya virus infection.

 

Most cases of disease have occurred in Africa, Asia, Europe, and the Indian and Pacific Oceans, but transmission of CHIK has been identified in Caribbean countries and South American regions, as well as foci in the southern United States. Infection with chikungunya virus may be suspected based on symptoms (fever, joint pain, and headache) and recent history of travel. A diagnosis of CHIK infection can be confirmed through laboratory tests on serum or cerebrospinal fluid.

 

This assay is designed to detect only species of clinical significance and is to be used for patients with a clinical history and symptoms consistent with chikungunya infection.

Reference Values

Negative

Interpretation

A positive test result indicates the presence of chikungunya virus RNA in the specimen.

 

A negative test result with a positive internal control indicates that chikungunya virus RNA is not detectable in the specimen.

 

A negative test result with a negative internal control is considered evidence of PCR inhibition or reagent failure. A new specimen should be collected for testing if clinically indicated.
