Why This Test Might Be Ordered
Your doctor may recommend this test if you have symptoms like frequent infections, fever, or signs of an immune system issue. It could also be part of a broader blood check-up or evaluation for conditions like leukemia, autoimmune diseases, or certain infections.
What to Expect Before the Test
No special preparation is needed. You’ll have a small needle inserted into your arm or hand to draw a small amount of blood. The process usually takes a few minutes, and you may feel a slight pinch. If you’re on blood thinners, let your doctor know before the test.
What the Results Mean
Results are typically reported as a count of neutrophils per microliter (µL) of plasma. While reference ranges vary by lab, very low counts (below normal) may indicate infections, bone marrow disorders, or immune deficiencies. Very high counts could suggest infections, inflammation, or other conditions.
Common Conditions Linked to Neutrophil Counts
Low neutrophil counts (neutropenia) may be linked to conditions like leukemia, severe infections, or certain medications. High neutrophil counts (neutrophilia) can occur with infections, stress, or inflammatory diseases. Your doctor will interpret results in the context of your overall health and symptoms.
