What's this test for?

This test is ideal if you're experiencing a lingering cough, chest pain, fever, or fatigue that hasn't gone away, especially if you've spent time in wooded or damp areas in the Midwest or Southeast US. It helps check for blastomycosis, a fungal infection that can affect the lungs and sometimes spread to skin or bones. It's especially relevant for men between 20-69, the group most commonly affected.

How should I prepare for this test?

How can you naturally support your immune system while dealing with a possible fungal infection? Getting enough sleep, staying hydrated, eating a nutrient-rich diet with plenty of fruits and vegetables, and avoiding smoking can all help your body's natural defenses work better. That said, these steps support general immune health but are not a substitute for appropriate testing and care if you have a confirmed or suspected infection.

What's included in this test?

This panel uses two different lab methods, Complement Fixation (CF) and Immunodiffusion (ID), to look for antibodies your body makes in response to the Blastomyces fungus. Using both methods together improves accuracy since each technique can catch different patterns of immune response, reducing the chance of a missed or false result.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what's considered a normal versus abnormal range for the antibody levels measured. If your results come back positive or borderline, the report will explain what that may mean and suggest next steps, such as retesting or seeking care promptly if symptoms are severe. You can download a standard lab report anytime from your account, and if you test again in the future, the trends feature lets you compare results side by side.

When will I get my results?

Results from this panel are typically ready within about 7 days after your sample is collected. This slightly longer turnaround is because the CF and ID methods both involve careful lab processing to detect antibody responses accurately. You'll get a notification as soon as your results are posted to your account.

Who should consider this test?

This test is a good option for men ages 20-69 who have unexplained respiratory symptoms like a persistent cough, chest pain, or fatigue, particularly if they live in or have visited the Ohio and Mississippi River valleys or Great Lakes regions. It's also useful for anyone with skin sores or bone pain of unknown cause who may have been exposed to soil or decaying wood. People with weakened immune systems who develop lung symptoms may also want to consider this test.

What symptoms indicate I may need this test?

Common signs include a cough that won't go away, chest pain, low-grade fever, night sweats, and unexplained weight loss. Some people also develop skin lesions, bone pain, or joint swelling if the infection has spread beyond the lungs. If you've had flu-like symptoms for weeks without improvement, especially after outdoor activity in wooded or riverbank areas, it may be worth investigating further.

What does a positive result mean?

A positive result means antibodies to the Blastomyces fungus were detected, suggesting your body has been exposed to or is currently fighting this infection. The level and pattern of antibodies detected by the CF and ID methods can help gauge how active the infection might be. Because blastomycosis can range from mild to serious, a positive result should prompt you to seek medical care right away, especially if you have ongoing respiratory symptoms.

What causes a false or unclear result?

Antibody tests like this one can sometimes show unclear results if the infection is very early, since your body hasn't built up enough antibodies yet, or if there's cross-reaction with other fungal infections like histoplasmosis. Timing matters too many people don't develop detectable antibody levels until a few weeks after exposure. If your result is unclear but symptoms persist, retesting after a couple of weeks can help clarify the picture.

How often should I retest?

If your first test comes back negative or unclear but your symptoms continue, retesting after 2-3 weeks is generally recommended to give your body more time to develop detectable antibodies. If you've been treated for a confirmed infection, your results report will guide whether follow-up testing makes sense to track improvement. Otherwise, this isn't a routine test that needs regular repeating unless you have new symptoms or exposure.
