A normal or "OK" blood count, specifically referring to Red Blood Cell (RBC) count, varies based on sex and tends to decrease with age.
Normal RBC Count Ranges
It's important to note that "OK" generally refers to falling within a population's normal range, but an individual's ideal range might be slightly different. A doctor can determine the ideal range on a case-by-case basis. According to the provided reference, the following RBC counts are generally considered within the normal range:
| Group | Normal RBC Count (x 1012/L) |
|---|---|
| Men | 4.0 to 5.9 |
| Women | 3.8 to 5.2 |
Factors Affecting RBC Count
Several factors can influence RBC count, including:
- Age: RBC levels typically decrease with age.
- Sex: Women generally have lower RBC counts than men. This difference is primarily due to hormonal variations.
- Altitude: People living at higher altitudes may have higher RBC counts. This is a physiological response to lower oxygen levels.
- Hydration: Dehydration can artificially increase RBC count, while overhydration can decrease it.
It's essential to consult with a healthcare professional for a thorough evaluation and interpretation of your specific blood count results. They can consider your individual circumstances, medical history, and other test results to determine if your blood count is within a healthy range for you.
