Hematocrit (Hct) is a blood test that measures the percentage of red blood cells (RBCs) in the total blood volume. It is an essential indicator of blood health, helping diagnose conditions like anemia, dehydration, and polycythemia.
A Hematocrit Calculator simplifies the calculation using known values such as Hemoglobin.
Formula:
The hematocrit can be calculated using the following formula:
Hematocrit (Hct) % = (Hemoglobin × 3)
Where:
- Hemoglobin = Hemoglobin level

🧮 Hematocrit (Hct) Calculator
📐 Formula:
Hematocrit (Hct) % = Hemoglobin × 3
How to Use the Hematocrit Calculator
- Input the Hemoglobin Level (in g/dl, e.g., 12.5–16.9 for adults).
- Calculate Hct using the formula:
- Compare with normal ranges (see below).
Normal Hematocrit Values & Interpretation
| Group | Normal Hct Range (%) |
|---|---|
| Adult Men | 38.8–50.0% |
| Adult Women | 34.9–44.5% |
| Children (1–15 yrs) | 30–42% |
| Newborns | 45–61% |
Interpretation
- Low Hct (Anemia): May indicate blood loss, iron deficiency, or chronic disease.
- High Hct (Polycythemia): Could suggest dehydration, lung disease, or bone marrow disorders.
Conclusion
A Hematocrit Calculator provides a quick way to estimate blood composition. By inputting RBC count and MCV, users can assess potential blood disorders and consult a healthcare provider if results are abnormal.
