What's this test for?

This test is ideal if you're experiencing a lingering cough, fever, chest pain, or fatigue that won't go away, especially if you've spent time in areas with bird or bat droppings, caves, or old buildings. It helps check whether a fungus called Histoplasma is causing a lung infection. It's also useful if you've already been treated for histoplasmosis and want to see how your body is responding over time.

What happens after I get my results?

Your results will show up in your account along with the normal reference range so you can see exactly where your number falls. If your titer is elevated, simple next steps include watching for worsening symptoms like breathing trouble or high fever and seeking medical care right away if those occur. You can download a standard lab report from your account at any time, and if you get retested later, the trends feature lets you compare results side by side to see if the infection is clearing.

What symptoms indicate I may need this test?

Common signs include a cough that won't quit, unexplained fever, night sweats, chest pain, weight loss, or fatigue that lasts for weeks. These symptoms are especially worth checking out if you've been in places with a lot of bird or bat droppings, like caves, chicken coops, or old barns. If you have a weakened immune system, even mild symptoms are worth investigating.

How can I naturally support my immune system while fighting an infection?
Getting enough sleep, staying hydrated, and eating a balanced diet with plenty of fruits, vegetables, and lean protein all help your body fight off infections more effectively. Avoiding smoking and excess alcohol also gives your immune system a better chance to recover. These habits support recovery but don't replace appropriate medical care if your infection is active or severe.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. You'll get a notification when they're ready to view in your account, so there's no need to call or wait on hold to find out.
Who should consider this test?
Anyone with a persistent respiratory illness that hasn't improved with standard treatment, especially after exposure to bird or bat droppings, caves, or construction sites in areas where histoplasmosis is common, should consider this test. People with weakened immune systems who develop unexplained fever or lung symptoms are also good candidates. It's also useful for tracking treatment progress if you've already been diagnosed.
What is histoplasmosis and why does it matter?
Histoplasmosis is a lung infection caused by breathing in spores from a fungus found in soil contaminated with bird or bat droppings. Most healthy people who are exposed have mild or no symptoms, but it can turn into a serious, long-lasting lung infection, especially in people with weaker immune systems. Catching and tracking it matters because untreated chronic infections can spread beyond the lungs.
What does a high antibody titer mean?
A titer of 1:32 or higher is considered a strong sign of active or recent Histoplasma infection. Higher numbers are more often seen in people with chronic, ongoing lung infections rather than a brief, mild exposure. If your titer is high along with symptoms, it's a good idea to seek prompt medical care.
How often should I retest?
If you're being treated for histoplasmosis, retesting every few weeks to months can help you see whether your antibody titer is dropping as your body clears the infection. If you had a single low-level result with no symptoms, retesting isn't usually needed unless new symptoms appear. Your lab report will include your specific number so you can track changes over time.
What should I do if my results are abnormal?
If your titer comes back elevated, keep track of your symptoms and how you're feeling day to day, and note any changes like fever, cough, or fatigue getting worse. Rest, stay hydrated, and avoid further exposure to dusty or contaminated environments like caves or old buildings. If symptoms are severe or worsening, such as trouble breathing or high fever, seek medical care right away.

Demo results
Histoplasma Antibody (Complement Fixation Titer) 1:32
Demo results
Negative (<1:8) Suggestive of Infection (≥1:32)
1:32

What this means

A titer of 1:32 or higher is considered highly suggestive of Histoplasma capsulatum infection. Higher titers are more often seen with chronic, ongoing lung infections rather than a mild recent exposure. This result, combined with symptoms, points toward an active or recent histoplasmosis infection.

* 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.
