Hematocrit Calculator

Calculate hematocrit (packed cell volume) from red blood cell count and hemoglobin concentration. Useful for assessing blood disorders and anemia.

Input Parameters

Calculation Results

Calculation Formula

Hematocrit (%) = (Red Blood Cell Count × Hemoglobin Concentration) / 35

Where:
- Red Blood Cell Count: Number of red blood cells per microliter of blood
- Hemoglobin Concentration: Amount of hemoglobin in grams per deciliter of blood
- 35: Conversion factor (based on typical average)

Hematocrit Calculator Usage Guide

Learn how to use the Hematocrit Calculator and understand its clinical significance

How to Use This Calculator

  1. Enter the Red Blood Cell Count (RBC) per µL in the first input field.
  2. Enter the Hemoglobin Concentration (g/dL) in the second input field.
  3. Click the "Calculate" button to compute the hematocrit percentage.
  4. The calculator will also provide an interpretation of whether the result is normal, low, or high.

Understanding Hematocrit

Hematocrit (also called packed cell volume or PCV) is the proportion of blood that is composed of red blood cells. It is expressed as a percentage of the total blood volume.

Normal Hematocrit Ranges

  • Males: 40-54% (typically 42-50%)
  • Females: 36-48% (typically 38-44%)

Clinical Significance

Hematocrit levels can indicate various health conditions:

  • Low hematocrit (Anemia): May be caused by iron deficiency, vitamin deficiencies, chronic diseases, or blood loss.
  • High hematocrit (Polycythemia): May be caused by dehydration, lung disease, or certain cancers.
