What Is a Normal CBC Level?
Normal ranges: Hemoglobin M: 13.5–17.5 / F: 12.0–16.0 g/dL; White Blood Cells 4,500–11,000/mcL; Platelets 150,000–400,000/mcL. Values outside these ranges may point to a condition that needs further evaluation.
Reference Range Table
| Marker | Low | Normal | High |
|---|---|---|---|
| Hemoglobin | M: <13.5 / F: <12.0 g/dL — anemia | M: 13.5–17.5 / F: 12.0–16.0 g/dL | Above range — polycythemia |
| White Blood Cells | Below 4,500/mcL — leukopenia | 4,500–11,000/mcL | Above 11,000/mcL — infection or inflammation |
| Platelets | Below 150,000/mcL — thrombocytopenia | 150,000–400,000/mcL | Above 400,000/mcL — thrombocytosis |
