What's this test for?

This test is ideal if you're experiencing frequent, severe, or unusual infections that don't seem to go away or keep coming back. It checks whether your immune system's white blood cells (neutrophils) can properly fight off bacteria and fungi. It's often used when there's concern about an underlying immune disorder like chronic granulomatous disease (CGD).

What's included in this test?

This test looks at how well your neutrophils, a type of white blood cell, respond to a challenge by producing key germ-fighting compounds. This process matters because when neutrophils can't perform this function properly, your body struggles to clear bacterial and fungal infections effectively, which can lead to repeated or serious illness.

What happens after I get my results?

Your results will be available in your account, with an explanation of the normal range for your result. Because this test is time-sensitive, the report will note the reference range that matches the age of your sample when it was processed. If your result falls outside the expected range, the report will explain what that may mean and suggest appropriate next steps, which may include seeking prompt medical care if infections are severe. You can download a standard lab report anytime and track any future related testing over time using the trends feature.

What is neutrophil oxidative burst and why does it matter?

Neutrophil oxidative burst is the process your immune cells use to produce natural germ-killing chemicals when they encounter bacteria or fungi. Think of it as your white blood cells launching a chemical attack against invaders. If this process doesn't work well, infections can become frequent, severe, or hard to clear, which is why testing this function matters for people with a history of unusual illness patterns.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. Because the accuracy of this test can be affected by how much time has passed since collection, timing of your sample matters for getting reliable results. You'll be notified as soon as your report is ready to view in your account.

Who should consider this test?

This test is a good fit for people who have had repeated, unusually severe, or hard-to-treat bacterial or fungal infections, especially starting in childhood. It's also useful for families with a known history of chronic granulomatous disease or other immune concerns. If infections seem to happen far more often than they should, this test can help explain why.

What symptoms indicate I may need this test?

Signs that may point to a need for this test include frequent skin abscesses, recurring pneumonia, swollen lymph nodes that don't resolve, or infections in the liver, bones, or other organs that keep coming back. Slow wound healing and frequent fungal infections can also be signs worth looking into. If these patterns sound familiar, this test can help identify whether an immune cell issue is involved.

How can I naturally support healthy immune cell function?

While this test measures a specific inherited or acquired immune function that isn't fixed by lifestyle alone, general immune health can be supported through good sleep, a balanced diet rich in fruits and vegetables, regular exercise, and avoiding smoking. Staying up to date on recommended vaccinations can also reduce your infection risk. If test results show reduced neutrophil function, these habits are still worthwhile, but medical guidance on managing the underlying condition is important.

What does an abnormal result mean?

An abnormal, low-burst result suggests your neutrophils may not be producing enough of the compounds needed to kill certain bacteria and fungi, which can increase your risk of infection. This finding is often followed up with additional testing to confirm the cause and understand the pattern. If you have an abnormal result and are currently dealing with signs of infection, such as fever or worsening symptoms, seek medical care promptly.

How often should I retest?

Retesting frequency depends on your individual health history and whether you've had prior abnormal results or ongoing infection concerns. Some people retest to confirm an initial abnormal finding, since specimen age can affect accuracy, while others use it as a one-time diagnostic step. If you're monitoring a known condition, periodic retesting can help track any changes over time using the trends feature in your account.
