Low WBC count, or leukopenia, puts patients at an increased risk of fungal and bacterial infections, according to LifeExtension. Patients with a low neutrophil count and fever may be treated with antibiotics, and antimicrobial therapy may be used to prevent future infections. When a low neutrophil count is expected, as is the case of chemotherapy, a doctor may choose to use either granulocyte colony-stimulating factors or granulocyte macrophage colony-stimulating factors to prevent leukopenia by stimulating bone marrow to produce white blood cells.
Leukopenia occurs when the WBC count is below 4,500 or the patient has fewer than 1,700 neutrophils in a single microliter of blood, as confirmed by MedlinePlus. Possible causes include liver disease, spleen disease, bone marrow deficiency, radiation treatment, certain viruses, severe bacterial infections, certain autoimmune disorders and certain cancer medications. A WBC count is performed by drawing blood from a vein located on the back of the hand or inside the elbow, and patients may feel throbbing at the site where the blood was drawn after the test is completed.Learn more about Medical Ranges & Levels
