What Is Included in This Test?
This screening includes a neutrophil count, which is a key part of a complete blood count (CBC). Neutrophils are the most abundant white blood cells and play a critical role in defending your body against bacterial infections. The test may also include other blood components depending on the lab’s panel setup, but the primary focus is on neutrophil levels in serum or plasma.
Why Might You Need This Test?
Doctors may order this test if you have symptoms of infection (such as fever, sore throat, or fatigue), if you’re at higher risk for infections (like after surgery or chemotherapy), or if you have conditions that affect your immune system (such as diabetes or autoimmune diseases). It can also be part of routine check-ups for certain populations.
How Is the Test Performed?
A blood sample is drawn from a vein, usually in your arm. The sample is then sent to a lab to analyze the number of neutrophils. The results are typically available within a few days, depending on lab processing times.
What Do the Results Mean?
Neutrophil counts can vary based on your health, diet, and other factors. High neutrophil counts may indicate infection, inflammation, or stress, while very low counts could signal immune deficiencies or other health issues. Your doctor will interpret the results in the context of your overall health and symptoms.
