Clinical Info
As an aid in the diagnosis of coccidioidomycosis (Valley fever). Negative fungal serology does not rule out the possibility of current infection. Positive results will reflex Coccidioides immunodiffusion testing. Note: This immunoassay uses recombinant and native Coccidioides antigens, including CF and TP antigens, typically detecting IgG and IgM, respectively.
