When Should I Worry About My White Blood Cell Levels?

[drelizabethblackburn]

White blood cell (WBC) levels indicate your immune system's health. Normal ranges are 4,000–11,000 per microliter. Low WBCs (leukopenia, below 4,000) may signal infections, autoimmune disorders, or bone marrow issues, requiring attention if persistent or paired with symptoms like fever or fatigue. High WBCs (leukocytosis, above 11,000) could indicate infections, inflammation, or leukemia, especially if accompanied by weight loss or bruising. For patients on medications like ceftriaxone injection wholesale or prescribed, monitor WBCs, as antibiotics can affect counts. Consult a doctor for abnormal results, recurring infections, or severe symptoms to determine underlying causes and necessary treatment.
