Coccidioides antibody test
No Coccidioides immitis antibodies are detected.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
Abnormal results mean that Coccidioides immitis antibodies are present. This can mean that you have a current or past infection.
The test may be repeated after several weeks to detect a rise in titer (antibody concentration), which confirms an active infection.
In general, the worse the infection, the higher the titer, except in people with a weakened immune system.
