Hematocrit is a blood test that measures the percentage of red blood cells (RBCs) in your blood. It is an important parameter used to diagnose and monitor various medical conditions, including anemia, dehydration, and blood disorders.
Hematocrit levels can vary depending on factors such as age, sex, and overall health. In this article, we will provide a comprehensive table outlining normal hematocrit levels for different age groups and genders.
Understanding Hematocrit
Before we dive into the normal hematocrit levels, let’s briefly understand what hematocrit represents. Hematocrit is expressed as a percentage and is a measure of the volume of red blood cells in relation to the total volume of blood.
It gives an indication of the blood’s oxygen-carrying capacity since RBCs are responsible for transporting oxygen to various tissues and organs in the body.
Normal Hematocrit Levels
The normal range of hematocrit levels can vary slightly between different laboratories and countries. The values provided in this table are general guidelines and may not apply to all individuals.
It’s always best to consult with your healthcare provider for an accurate interpretation of your hematocrit results.
Hematocrit Levels in Adults
| Age Group | Male | Female |
|---|---|---|
| 18-45 years | 38.8% – 50% | 34.9% – 44.5% |
| 46-65 years | 37.5% – 49.4% | 34.9% – 44.5% |
| Above 65 years | 36.4% – 46.4% | 35.5% – 45.1% |
The above table represents the normal hematocrit levels for adults based on age and gender. It’s important to note that these ranges are approximate and can vary slightly depending on individual factors.

Hematocrit Levels in Children
Hematocrit levels in children can vary based on age and developmental stage. Here’s a table outlining the normal hematocrit levels for children:.
| Age Group | Male | Female |
|---|---|---|
| Newborn | 55% – 68% | 47% – 62% |
| 1-2 weeks | 47% – 65% | 41% – 56% |
| 1 month | 37% – 49% | 32% – 42% |
| 3 months | 30% – 36% | 29% – 38% |
| 6 months | 35% – 45% | 31% – 41% |
| 1 year | 34% – 40% | 32% – 38% |
It’s important to remember that these ranges are general guidelines, and individual variations may occur. Discussing your child’s hematocrit levels with a pediatrician is always recommended.
Factors Affecting Hematocrit Levels
Hematocrit levels can be influenced by various factors, including:.
- Anemia: Low levels of RBCs can lead to a decreased hematocrit level.
- Dehydration: When the body is dehydrated, the concentration of RBCs increases, leading to a higher hematocrit level.
- Age: Hematocrit levels tend to decrease with age.
- Sex: Typically, women have slightly lower hematocrit levels compared to men.
- Altitude: At higher altitudes, the body produces more RBCs to compensate for decreased oxygen levels, resulting in higher hematocrit levels.
- Medical conditions: Certain medical conditions, such as kidney disease and bone marrow disorders, can affect hematocrit levels.
Interpreting Hematocrit Levels
Interpreting hematocrit levels requires a comprehensive evaluation of an individual’s medical history, symptoms, and other laboratory tests. Abnormal hematocrit levels can be an indication of an underlying health condition.
If your hematocrit levels fall outside the normal range, your healthcare provider may recommend further investigations to determine the cause and appropriate treatment.
Conclusion
Hematocrit levels play an essential role in assessing an individual’s overall health and helping diagnose various medical conditions. The normal range of hematocrit levels varies depending on factors such as age, sex, and overall health.
It’s important to consult with your healthcare provider for a personalized interpretation of your hematocrit results. Regular health check-ups and maintaining a healthy lifestyle can contribute to maintaining optimal hematocrit levels.
