FDA Status
This test was developed and its performance characteristics determined by MiraVista Diagnostics. It has not been cleared or approved by the FDA; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
Setup Schedule
Monday-Friday Morning Report available: Next Day
Limitations
The result is not intended to be used as the sole means for clinical diagnosis or patient management decisions. Cross reactions are seen with histoplasmosis, blastomycosis and paracoccidioidomycosis.
Sputolysin, sodium hydroxide, and potassium hydroxide treatment degrade the analyte detected in the assay.

Clinical Significance
The coccidioides quantitative antigen test aids in the diagnosis of coccidioidomycosis. Monitoring the coccidioidomycosis helps determine when treatment can be stopped and to diagnose relapse.
