Clinical Significance
Detection of antibodies to Coccidioides antigens plays an important role in identifying patients with coccidioidomycosis. Antibodies to Coccidioides TP antigen usually appear during the first week of infection, and remain detectable for approximately 5 months; their detection indicates recent, active infection. Antibodies to Coccidioides F antigen appear within a month of infection, and remain detectable for up to a year thereafter.
