Note

For Coccidioides, immunodiffusion (ID) measures IgM antibody, while complement fixation (CF) measures both IgG and IgM. ELISA tests can be used to detect both coccidioidal IgG and IgM antibodies. While elevated single antibody titers may be diagnostic, paired specimens are preferred. Acute and convalescent specimens (drawn at least 21 days apart) showing a fourfold or greater rise in titer are diagnostic.

Negative fungal serology does not rule out the possibility of current infection.
