Fast, Direct-Access Valley Fever Lab Testing
Valley Fever—clinically known as Coccidioidomycosis—is a fungal infection caused by Coccidioides, a microscopic fungus that lives in the soil of the southwestern United States, including Arizona, southern California, Nevada, New Mexico, and parts of Texas.
When dry desert soil gets disturbed by construction, gardening, off-roading, hiking, or even strong winds, fungal spores become airborne. Breathing in those spores is how people get infected. You can't catch Valley Fever from another person—it spreads only through environmental exposure to the fungus.
Maricopa and Pinal counties report some of the highest Valley Fever rates in the country. Up to 3% of Arizona residents are exposed to the fungus every year, though many people never develop symptoms or only experience mild flu-like illness.
Symptoms of Valley Fever
Most people who develop symptoms experience them 1 to 3 weeks after exposure, though some patients don't notice symptoms for longer.
Common valley fever symptoms include the following:
-
Persistent dry cough (often called the "desert cough") that lasts for weeks
-
Fever and night sweats
-
Severe fatigue that doesn't improve with rest
-
Headache
-
Muscle aches and joint pain
-
Chest pain
-
Shortness of breath
-
Rash (especially on the lower legs)
-
Unintended weight loss
Symptoms can range from mild — easily mistaken for flu or a bad cold — to severe, especially if the infection spreads beyond the lungs. If your "cold" or "flu" has lasted more than 2 weeks, Valley Fever testing is worth considering.
In rare cases, the infection can spread to the brain, bones, joints, skin, or other organs (a condition called disseminated coccidioidomycosis). These cases are serious and require specialist treatment.

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.

Valley Fever FAQ
What are the symptoms of Valley Fever? Valley Fever often feels like a lingering cold, flu, or pneumonia: fatigue, cough, fever, chest pain, headache, night sweats, and sometimes a rash. Symptoms can last for weeks and are easy to mistake for other illnesses. If a respiratory illness isn't improving — especially here in Arizona — testing is worth considering.
Do I need a doctor's order to get tested for Valley Fever? No. We're a direct-access lab, so you can walk in for a Valley Fever blood test without a doctor's order or insurance. It's a simple blood draw, and your secure results are delivered to your online portal — often a faster path than waiting on an urgent care or specialist referral.
What does the Valley Fever blood test show, and can a negative result be wrong? The test detects antibodies your immune system makes against the Valley Fever fungus. A positive points to a current or recent infection. Because antibodies take one to three weeks to build, a very early negative doesn't fully rule it out — if symptoms persist, retesting later may be recommended.
