What's this test for?

This test is ideal if you're experiencing symptoms of a serious infection that hasn't improved with usual treatment, especially if you have a weakened immune system. It helps if you have a history of blood cancers, an organ or stem cell transplant, or are on immune-suppressing medication, since these situations raise your risk for invasive fungal infections. It's a way to check your blood for signs of certain fungi without needing an invasive procedure.

What happens after I get my results?

Your results will show up in your account as either positive or negative, with an explanation of what that range means. If your result is positive, this is a signal to seek medical care promptly since invasive fungal infections can progress quickly, especially in people with weakened immune systems. A negative result is reassuring but doesn't rule out every type of fungal infection, so continued monitoring of symptoms matters. You can download the full lab report from your account any time, and if you retest later, you'll be able to track changes over time using the trends feature.

Who should consider this test?

People with weakened immune systems are the main group who should consider this test, including those with blood cancers, organ or stem cell transplants, or anyone on long-term immune-suppressing medication. It's also useful for people showing signs of a serious, unexplained infection that standard tests haven't identified. If you fall into a higher-risk category and have symptoms like persistent fever or feeling unusually unwell, this test can provide helpful information quickly.

What symptoms indicate I may need this test?

Common signs that might point to needing this test include an unexplained, persistent fever that doesn't respond to antibiotics, unusual fatigue, or feeling seriously unwell without a clear cause. People with weakened immune systems may also notice worsening respiratory symptoms or signs of infection that keep coming back. If you're in a high-risk group and have any of these symptoms, this test can help provide answers alongside other clinical information.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. Once ready, they'll be posted directly to your secure online account so you can view them right away. You'll also be able to download a full report for your records at any time.

What is (1-3)-beta-D-glucan and why does it matter?

(1-3)-beta-D-glucan is a substance found in the cell walls of many types of fungi. When it shows up in your blood, it can be a sign that fungi are present somewhere in your body, even in hard-to-reach places. This matters because invasive fungal infections can be serious, especially for people with weakened immune systems, and catching them early can make treatment more effective.

What does a positive result mean?

A positive result means the test detected fungal cell wall material in your blood, which suggests a possible fungal infection somewhere in your body. It doesn't tell you exactly which type of fungus is involved, since this test detects a substance shared across many different fungi. Because this finding can be serious, especially if you have a weakened immune system, it's important to seek medical care right away for further evaluation.

What can cause a false positive or false negative result?

False positives have been linked to certain blood products like albumin or immunoglobulins, and even contact with glucan-containing gauze or surgical sponges during sample collection. False negatives can happen because not every fungal infection raises blood levels of this substance, and this test doesn't detect certain fungi like Mucorales, Blastomyces, or Cryptococcus. This is why results are meant to be considered alongside your symptoms and other test findings rather than as a standalone answer.

How often should I retest?

Retesting frequency really depends on your individual risk level and symptoms, but people in ongoing high-risk situations, like active cancer treatment or post-transplant care, may need repeat testing periodically to monitor for changes. If your first result was negative but symptoms persist or worsen, retesting can help catch an infection that may not have been detectable earlier. Using the trends feature in your account can help you and your care team see patterns over multiple tests.

What should I do if my results are abnormal?

If your result comes back positive, treat this as a signal to seek medical care as soon as possible, particularly if you have a weakened immune system or ongoing symptoms. In the meantime, keep track of any new or worsening symptoms like fever, fatigue, or breathing issues, since this information is useful for further evaluation. Because invasive fungal infections can progress quickly, don't wait to act on a positive result.
