Segmented Neutrophils: What They Mean in Your Bloodwork
What Does Seg Neutrophils Mean in a Blood Test?
Neutrophils are a type of white blood cell that helps the body fight infection. Segmented neutrophils (segs) are mature neutrophils that have a characteristic segmented nucleus. They are the most common type of neutrophil found in the blood.
What Do Seg Neutrophils Do?
Segmented neutrophils play an important role in the immune system. They are phagocytes, which means that they can engulf and destroy foreign particles, such as bacteria and viruses. They also release antimicrobial substances that can kill bacteria.
What Does Seg Neutrophils Mean in a Blood Test?
The absolute neutrophil count (ANC) is a measure of the number of neutrophils in a sample of blood. The ANC is calculated by multiplying the total white blood cell count (WBC) by the percentage of neutrophils in the blood.
A high ANC may indicate an infection or inflammation. A low ANC may indicate a bone marrow disorder or a problem with the immune system.
Normal Segmented Neutrophil Range
The normal range of ANC for adults is 1,500 to 8,000 cells per microliter (mL) of blood.
Conditions That Can Affect Segmented Neutrophil Count
A number of conditions can affect the segmented neutrophil count, including:
- Infections: Bacterial and viral infections can cause an increase in the ANC. - Inflammation: Non-infectious conditions, such as inflammatory bowel disease and rheumatoid arthritis, can also cause an increase in the ANC. - Bone marrow disorders: Disorders that affect the bone marrow, such as leukemia and aplastic anemia, can cause a decrease in the ANC. - Immune system disorders: Disorders that affect the immune system, such as HIV/AIDS, can also cause a decrease in the ANC.
When to See a Doctor
If you have a high or low ANC, it is important to see a doctor to determine the cause.
Treatment for Segmented Neutrophil Abnormalities
The treatment for segmented neutrophil abnormalities depends on the underlying cause. Treatment for an infection may include antibiotics. Treatment for a bone marrow disorder may include chemotherapy or a bone marrow transplant. Treatment for an immune system disorder may include medications to suppress the immune system.
