What Your Results Mean
Positive Result — Antibodies Detected
Your body has produced antibodies against the Valley Fever fungus. This usually means you're currently fighting the infection or have recently fought it. A positive result doesn't tell you how severe your case is—you'll need a follow-up with a healthcare provider to discuss next steps. We recommend taking your results to your primary care doctor or urgent care provider
Negative Result — No Antibodies Detected
No Valley Fever antibodies were found in your blood.
This usually means you don't have Valley Fever
but there's an important caveat:
Antibodies can take 2 to 6 weeks to build up to detectable levels. If you've had symptoms for less than 2-3 weeks and your test comes back negative, consider retesting in 2 to 3 weeks. Up to one-third of Valley Fever patients initially test negative before later testing positive.
