Coccidioidomycosis antibody test
No precipitins is normal. This means the blood test did not detect the antibody to Coccidioidies immitis.
An abnormal (positive) result means the antibody to Coccidioides immitis has been detected.
In this case, another test is done to confirm that you have an infection. See: CSF coccidioides complement fixation. This test is rarely done. It has mostly been replaced by immunodiffusion tests.
