Coccidioides antigen testing, used to diagnose coccidioidomycosis (also known as valley fever), detects the presence of fungal antigens in bodily fluids like urine, serum, or cerebrospinal fluid. This aids in faster and more accurate diagnosis, especially in immunocompromised individuals or those with severe disease.
To detect the presence of Coccidioides fungal antigens in bodily fluids, indicating an active infection.
Antigen tests, like the MiraVista Diagnostics MVista® Coccidioides Quantitative Ag EIA, look for specific fungal proteins (antigens) produced by the Coccidioides fungus.
Antigen testing is often used alongside antibody tests (e.g., EIA, immunodiffusion, and complement fixation) for a more comprehensive diagnosis.
Diagnosis of Meningitis: Antigen detection in CSF is crucial for diagnosing coccidioidal meningitis.
Faster Diagnosis: Antigen testing can lead to quicker diagnosis than traditional antibody testing.
Improved Sensitivity: Antigen tests can be more sensitive, especially in immunocompromised patients or those with severe disease.
Monitoring Treatment: Antigen tests can help monitor treatment effectiveness and detect relapses.
