What's this test for?

This test is ideal if you're experiencing unexplained fever, fatigue, weight loss, or breathing problems that won't go away, especially if you've spent time in areas with bat or bird droppings where a fungus called Histoplasma is common. It helps check whether that fungus has spread through your body, a condition called disseminated histoplasmosis. It's also useful if you have a weaker immune system and your symptoms aren't improving with typical treatments.

What's included in this test?

This test measures a specific marker called galactomannan that the Histoplasma fungus releases into urine when it's actively spreading through the body. Checking for this marker matters because it can pick up on infections that are harder to catch with blood tests alone, especially in people whose immune systems are struggling to fight it off.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative result means. If your result is positive, next steps usually involve seeking care quickly since disseminated histoplasmosis can become serious if untreated, while a negative result combined with ongoing symptoms may mean retesting or additional testing is worth considering. You can download a standard lab report from your account at any time, and if you test again in the future, you'll be able to track your results over time using the trends feature.

How can I naturally support my immune system?

While there's no natural remedy that treats an active fungal infection, keeping your immune system strong can help your body respond better overall. Getting enough sleep, eating a balanced diet with plenty of protein and vegetables, managing stress, and avoiding smoking all support immune function. If you have a condition that weakens your immune system, working on managing that condition is one of the most impactful things you can do.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll receive a notification once they're posted to your account so you can log in and view them, along with an explanation of what the result means.

Who should consider this test?

This test is a good option for people with ongoing unexplained fever, weight loss, or breathing symptoms, particularly those who live in or have visited areas where Histoplasma is common, such as river valleys in the central and eastern United States. It's especially relevant for people with weakened immune systems, since they're more likely to develop the disseminated form of the infection. Anyone whose symptoms haven't improved with standard treatment may also want to consider this test.

What symptoms indicate I may need this test?

Common signs include a fever that won't go away, night sweats, unexplained weight loss, persistent cough or shortness of breath, and extreme tiredness. Some people also notice mouth sores, an enlarged liver or spleen, or skin changes. If you've had these symptoms for weeks without a clear cause, this test can help identify whether a spreading fungal infection is the reason.

What does a positive result mean?

A positive result means the galactomannan marker was found in your urine, which suggests the Histoplasma fungus is actively present and likely spreading in your body. This is taken seriously because disseminated histoplasmosis can affect multiple organs if it isn't addressed. If you get a positive result, it's important to seek medical care promptly, especially if you're experiencing severe symptoms.

How often should I retest?

If you're being monitored for an active infection, retesting every few weeks can help track whether the level of the marker is going down, which suggests improvement. If your first test was negative but your symptoms continue, retesting after a couple of weeks may help catch an infection that was too early to detect the first time. Your situation may call for a different schedule depending on how you're feeling.

What should I do if my results are abnormal?

If your result comes back positive, don't wait to seek medical care, especially if you have a weakened immune system or your symptoms are severe, since this infection can progress quickly. In the meantime, focus on rest, staying hydrated, and monitoring your symptoms closely. If you experience severe shortness of breath, confusion, or very high fever, seek emergency care right away.
