The normal range for a Complete Blood Count (CBC) varies depending on the specific component being measured and, in some cases, the sex of the individual. Here's a breakdown of the typical reference ranges based on the provided reference:
Complete Blood Count Reference Ranges
| Blood Component | Abbreviation | Reference Range |
|---|---|---|
| White Blood Cells | WBC | 4,500 - 11,000 /mm3 |
| Red Blood Cells | RBC | Male: 4.3 - 5.9 million/mm3 Female: 3.5 - 5.5 million/mm3 |
| Hemoglobin | HGB | Male: 13.5 - 17.5 g/dL Female: 12.0 - 16.0 g/dL |
| Hematocrit | HT | Male: 41% - 53% Female: 36% - 46% |
Key Components and Their Significance
- White Blood Cells (WBC): These are crucial for the immune system, defending the body against infection and disease. The reference range is 4,500 - 11,000 per cubic millimeter of blood.
- Red Blood Cells (RBC): These cells are responsible for carrying oxygen throughout the body. The normal ranges vary by sex, being slightly higher for males (4.3 - 5.9 million/mm3) than females (3.5 - 5.5 million/mm3).
- Hemoglobin (HGB): This protein within red blood cells binds to oxygen, facilitating its transport. Similar to RBCs, normal ranges differ between sexes, with males typically having a higher range (13.5 - 17.5 g/dL) than females (12.0 - 16.0 g/dL).
- Hematocrit (HT): This is the proportion of blood volume made up of red blood cells. Again, males have a slightly higher range (41% - 53%) compared to females (36% - 46%).
Important Considerations:
- These reference ranges are general guidelines. The specific normal ranges can differ slightly based on the laboratory and the individual's age, medical history, and overall health.
- It is essential to consult with a healthcare provider for proper interpretation of CBC results. Abnormal values may indicate various health conditions and may need further investigation.
