Why This Test Might Be Ordered

Your healthcare provider may order this test to check for infections, inflammation, or other conditions that affect your immune system. It can also help diagnose or monitor diseases like leukemia, autoimmune disorders, or certain infections.

What to Expect Before the Test

No special preparation is needed for this test. You may have a small needle inserted into your arm or hand to draw blood. The process usually takes a few minutes, and you can resume normal activities afterward.

What the Results Mean

Results are typically reported as a count of neutrophils per microliter (µL) of blood. High or low neutrophil counts can indicate different health issues, so it’s important to discuss your results with your healthcare provider.

Common Conditions Affecting Neutrophil Counts

High neutrophil counts might suggest infections, stress, or certain inflammatory conditions. Low neutrophil counts could indicate immune deficiencies, infections, or medications that suppress the immune system.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Neutrophils play a critical role in defending against bacterial infections. Abnormal counts can signal underlying health problems that require further medical evaluation, such as infections, chronic diseases, or immune disorders.
