What's this test for?

This test is ideal if you're experiencing a lingering cough, fatigue, chest pain, fever, or joint aches that won't go away, especially if you've spent time in dry, dusty areas of the Southwest US. It checks for antibodies your body makes when fighting Coccidioides immitis, the fungus that causes Valley Fever. It's also useful if you've had unexplained pneumonia-like symptoms that haven't improved with typical treatments.

What's included in this test?

This test measures a single, specific marker: antibodies against Coccidioides immitis using the complement fixation method. This approach matters because complement fixation antibody levels can also give a sense of how active or severe the infection is, which is useful information beyond just a yes/no answer.

What happens after I get my results?

Your results will show up in your online account with the normal range clearly explained so you know exactly what your number means. If your result is negative but symptoms continue, retesting in a few weeks may be worth considering since antibodies can take time to develop. If your result is positive, especially with severe symptoms like trouble breathing or confusion, seek medical care right away since the infection can sometimes spread. You can download a standard lab report anytime and use the trends feature to track your results if you test again later.

How can I naturally support my immune system while recovering?
Getting enough sleep, staying hydrated, and eating a diet rich in fruits, vegetables, and lean protein can help your immune system fight off fungal infections like Valley Fever. Avoiding smoking and limiting alcohol also gives your body a better chance to recover. Light exercise, like walking, can help maintain energy without overtaxing your body while you heal. However, don't rely on natural remedies alone if your symptoms are severe or worsening.
When will I get my results?
Results for this test are typically ready within about 7 days of your sample being collected. You'll receive a notification once your results are posted to your online account, where you can view them along with an explanation of what the values mean.
Who should consider this test?
Anyone with unexplained respiratory symptoms who lives in or has recently traveled to areas like Arizona, California's Central Valley, or other parts of the Southwest US where this fungus is common in soil should consider this test. It's also worth considering if you have a weakened immune system and have been exposed to dusty, dry environments, since you may be at higher risk for more serious illness.
What symptoms indicate I may need this test?
Common symptoms include a persistent cough, fatigue, fever, night sweats, chest pain, and joint or muscle aches that last for weeks. Some people also notice a skin rash or unusual bumps. If these symptoms started after spending time outdoors in dusty regions of the Southwest, this test can help figure out if Valley Fever is the cause.
What does a high antibody titer mean?
A high complement fixation antibody titer generally means your immune system is mounting a strong response to the fungus, which can suggest a more active or widespread infection. Higher titers are sometimes linked to a greater chance of the infection spreading beyond the lungs. This finding usually calls for closer monitoring and, if symptoms are significant, prompt medical attention.
What causes a positive Coccidioides antibody result?
A positive result happens when you've been exposed to and infected by Coccidioides immitis spores, typically by breathing in dust from contaminated soil. This is most common in dry, arid regions like Arizona and California's Central Valley, particularly during dusty conditions like construction, farming, or windstorms. Some people fight off the infection with mild or no symptoms, while others develop more noticeable illness.
How often should I retest?
If your first test is negative but symptoms persist, retesting after 2-3 weeks is often recommended since it can take time for antibodies to reach detectable levels. If you've already been diagnosed and are monitoring an active infection, periodic retesting can help track whether antibody levels are rising or falling over time, which reflects how the infection is responding. Use the trends feature in your account to keep an eye on any changes.

What this means

A negative result means no significant antibodies to Coccidioides immitis were detected, suggesting no current or past infection with Valley Fever fungus. If you have symptoms and were tested very early in the illness, a false negative is possible since antibodies take time to develop.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
