Detecting an immune response
The immune response is how your body recognizes and defends itself against organisms that can cause diseases like Valley Fever.
SPHERUSOL is a skin test performed if your doctor has determined you have a history of Valley Fever (pulmonary coccidioidomycosis). The purpose of the test is to see if you have developed an immune response to the fungus (Coccidioides) that causes Valley Fever.
o The Valley Fever infection is early
o The Valley Fever infection is severe
o Other infections or conditions interfere with the immune response
o Certain drugs that affect the immune system can interfere with the immune response
