What's this test for?

This test is ideal if you're experiencing unexplained infections, unusual bruising, or if you or your newborn have been diagnosed with a low white blood cell count. It looks for antibodies that attack neutrophils, a type of white blood cell that helps your body fight infection. It's often used when a transfusion reaction, autoimmune condition, or newborn blood disorder is suspected.

What happens after I get my results?

Your results will show up in your online account with a clear explanation of what a normal range looks like for this antibody test. If your result comes back positive, next steps usually involve retesting or additional follow-up to confirm the finding, and if you have severe symptoms like fever or frequent infections, seek medical care right away. You can download a standard lab report from your account at any time, and if you test again in the future, the trends feature lets you compare results side by side.

Who should consider this test?

This test is a good fit for newborns with unexplained low neutrophil counts, adults with recurring infections of unknown cause, and people who had a bad reaction during a blood transfusion. It's also useful if you have a suspected autoimmune condition or started a new medication and developed a sudden drop in white blood cells. If any of these situations apply to you or your baby, this test can help identify the cause.

What symptoms indicate I may need this test?

Watch for frequent or unusual infections, fevers that keep coming back, mouth sores, or slow-healing wounds, since these can point to a low neutrophil count. Newborns may show signs like skin infections or umbilical cord infections shortly after birth. If you recently had a transfusion and had a fever, chills, or breathing trouble during or after it, that's also a reason to consider this test.

When will I get my results?

Results from this test are typically ready within about 7 days of your lab visit. This timeframe allows the lab to run the specialized flow cytometry analysis needed to detect neutrophil antibodies accurately. Once ready, you'll be notified and can view the full report in your account.

What is a neutrophil antibody and why does it matter?

A neutrophil antibody is a protein your immune system sometimes makes by mistake, and it attacks your own neutrophils, which are white blood cells that fight off infections. When these antibodies are present, they can cause a condition called neutropenia, where you have too few neutrophils to protect you properly. This matters because low neutrophil levels can make even minor infections turn serious quickly.

What does a positive result mean?

A positive result means antibodies against neutrophils were found in your blood, which can explain symptoms like frequent infections or a low white blood cell count. This doesn't automatically mean something is seriously wrong, but it does point to an immune-related cause that's worth tracking. Simple next steps include monitoring your white blood cell counts over time and avoiding unnecessary exposure to infections while levels are low.

What causes neutrophil antibodies to develop?

Neutrophil antibodies can develop for several reasons, including pregnancy (where a mother's immune system reacts to a baby's blood cells), certain medications, autoimmune conditions, or past blood transfusions. In newborns, the condition is usually temporary and related to antibodies passed from mother to baby. Identifying the trigger, like a specific drug, can help guide next steps.

How often should I retest?

If your first result is positive, retesting after any suspected trigger (like starting a new medication) is stopped is often recommended to see if levels return to normal. For newborns, doctors typically monitor levels over the first few weeks of life since the condition often resolves on its own. If you're symptom-free and had a negative result, there's usually no need to retest unless new symptoms appear.

What should I do if my results are abnormal?

If your results show neutrophil antibodies, focus on protecting yourself from infection by washing your hands frequently, avoiding crowded places when possible, and keeping an eye on any cuts or wounds for signs of infection. Track your symptoms and consider a follow-up test to see if levels change over time. If you develop a fever, chills, or a rapidly worsening infection, seek medical care immediately since this can be a sign your body needs help fighting it off.
