A normal blood count varies slightly depending on the laboratory and individual factors like age and sex, but generally falls within specific ranges. A complete blood count (CBC) measures several components of your blood, providing valuable insights into your overall health.
Key Blood Components and Normal Ranges
The following table summarizes the typical normal ranges for key blood components, referencing data from various reputable sources including the National Center for Biotechnology Information (NCBI):
| Blood Component | Abbreviation | Typical Range (Men) | Typical Range (Women) | Units | Notes |
|---|---|---|---|---|---|
| White Blood Cells (WBC) | WBC | 4,500 - 11,000 | 4,500 - 11,000 | cells/µL or 109/L | Also known as leukocytes; fight infection. |
| Red Blood Cells (RBC) | RBC | 4.3 - 5.9 million/mm3 or 4.3 - 5.9 x 1012/L | 3.5 - 5.5 million/mm3 or 3.8 - 5.2 x 1012/L | cells/µL or 1012/L | Carry oxygen throughout the body. Variations exist across sources. |
| Hemoglobin (HGB) | HGB | 13.5 - 17.5 g/dL | 12.0 - 16.0 g/dL | g/dL | Protein in RBCs that carries oxygen. Variations exist across sources. |
| Hematocrit (HT) | HT | 41% - 53% | 36% - 46% | % | Percentage of RBCs in blood volume. Variations exist across sources. |
Note: These ranges are approximate. Always consult your doctor or healthcare provider to interpret your specific blood count results.
Understanding Your Blood Count Results
Your doctor will consider your individual medical history and other factors when interpreting your blood count. Variations outside the typical ranges may indicate various health issues, requiring further investigation. For example, a low RBC count might suggest anemia, while an elevated WBC count could signal an infection.
Importance of a Complete Blood Count (CBC)
A CBC is a routine blood test that provides crucial information about your blood health. It helps diagnose and monitor various conditions. It is a vital tool for preventative care and detecting a wide range of issues.
