What Is a Neutrophil Count Used For?

Doctors use this test to diagnose and monitor conditions like infections, autoimmune diseases, or blood disorders. It helps assess how well your immune system is responding to illness or treatment.

How Is This Test Performed?

A small amount of blood is drawn from a vein in your arm. The sample is then analyzed to count the number of neutrophils in your blood cells.

What Might Affect Your Results?

Factors like recent infections, stress, certain medications (e.g., steroids), or blood disorders can influence neutrophil levels. Recent blood donation or exercise may also temporarily affect results.

Interpreting Your Results

Results are compared to standard ranges for healthy adults. Very high or very low counts may require further evaluation by your healthcare provider.

Clinical interpretation
