Chikungunya IgM, Antibody, Serum
Use
Aiding in the diagnosis of recent infection with Chikungunya virus by detecting IgM antibodies in patients with recent travel to endemic areas and a compatible clinical syndrome. Chikungunya virus is a single-stranded RNA alphavirus endemic throughout Africa, India, and the Caribbean islands. Individuals exposed to ChikV often present with high fever, incapacitating joint pain, and rash. This test assists in evaluating recent exposures and infections, complementing clinical observations and patient history.
Special Instructions
Not provided.
Limitations
Specimens collected too early following infection may be negative for antibodies. Testing of convalescent serum is recommended. Chikungunya and Dengue viruses co-circulate, so infections may have overlapping symptoms. Evaluate patients for both viruses. IgM antibodies may remain detectable for 3 to 4 months after infection.
