Coccidioides Antibodies (IgG, IgM), Immunodiffusion with Reflex to Complement Fixation

Use

Detection of antibodies to Coccidioides antigens aids in identifying patients with coccidioidomycosis. Antibodies to the TP (IgM) antigen appear during the first week of infection and remain detectable for approximately 5 months, indicating recent, active infection. Antibodies to the F (IgG) antigen appear within a month of infection and remain detectable for up to a year thereafter.
