What's this test for?

This test is ideal if you're experiencing a lingering cough, fever, night sweats, joint pain, or skin sores that haven't gone away, especially if you've spent time outdoors in wooded or moist soil areas where the blastomyces fungus lives. It helps check whether a fungal infection called blastomycosis could be causing your symptoms. This is especially useful if standard treatments for colds or bronchitis haven't helped.

What's included in this test?

This test measures antibodies your immune system produces in response to the blastomyces fungus, using a method called complement fixation. Tracking these antibody levels helps show whether your body has recently encountered this specific fungus, which can point toward a fungal lung or skin infection rather than a bacterial or viral one.

What happens after I get my results?

Your results will show up in your account with your titer value and an explanation of what's considered a normal versus elevated range. Because a single test can't always confirm or rule out infection, a common next step is retesting a few weeks later to see if the titer level has changed significantly. If your result is elevated or you notice worsening symptoms like difficulty breathing, seek medical care right away. You can download the full lab report anytime and use the trends feature to track any changes over time.

What is Blastomyces and why does it matter?

Blastomyces is a type of fungus found in soil and decaying wood, especially in humid regions near lakes and rivers. When inhaled, it can cause an infection called blastomycosis that mainly affects the lungs but can spread to skin, bones, or other organs if untreated. Knowing whether this fungus is present matters because it needs targeted antifungal treatment rather than typical antibiotics.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted to your account, where you can view your titer value and what it means in plain language.

Who should consider this test?

This test is worth considering if you live in or have recently traveled to areas like the Midwest, southeastern U.S., or Great Lakes region and have unexplained respiratory symptoms, skin lesions, or joint pain. It's also useful if you work outdoors in soil, construction, or forestry and have symptoms that haven't improved with typical treatment. People with weakened immune systems who develop persistent infections may also benefit from checking for this fungus.

What symptoms indicate I may need this test?

Common signs include a cough that won't go away, low-grade fever, night sweats, unexplained weight loss, joint or bone pain, and skin bumps or sores that don't heal. These symptoms can look like pneumonia or a bad cold at first, which is why fungal infections are sometimes missed. If you've had these symptoms for weeks without improvement, it may be worth checking for a fungal cause.

What does a high antibody titer mean?

A higher titer, especially one that rises four-fold or more between two tests taken weeks apart, suggests your immune system is actively responding to a blastomyces infection. On its own, one high result isn't a definite diagnosis, since other similar fungal infections can sometimes cause a mild reaction too. Retesting and looking at your symptoms together give a clearer picture.

What causes a rise in blastomyces antibodies?

Antibody levels rise when your body is actively fighting off exposure to the blastomyces fungus, usually after breathing in spores from disturbed soil, wood, or decaying leaves. Activities like gardening, construction, hunting, or hiking in wooded or riverside areas increase your chances of exposure. Weakened immunity can also make an existing infection more likely to trigger a stronger antibody response.

How often should I retest?

Because a single result can be inconclusive, retesting about 2 to 3 weeks after your first test is typically recommended to check for a rising titer. If your levels are dropping over time, it can be a good sign that your body is clearing the infection. Continue to monitor for any new or worsening symptoms in between tests.
