1. What is Differential WBC Calculation?

Differential WBC calculation determines the percentage of each type of white blood cell in a blood sample. This helps in diagnosing various medical conditions and monitoring immune system function.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Cell\ Type\ Count \) — Number of specific white blood cells counted
• \( Total\ WBC \) — Total number of white blood cells counted

Explanation: This formula calculates the proportion of a specific white blood cell type relative to the total white blood cell count, expressed as a percentage.

3. Importance of Differential WBC Calculation

Details: Differential WBC counts are essential for diagnosing infections, inflammatory conditions, allergies, and various blood disorders. They provide valuable information about the body's immune response.

4. Using the Calculator

Tips: Enter the cell type count and total WBC count as whole numbers. Ensure values are valid (cell count ≥ 0, total WBC > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are the main types of white blood cells?
A: The main types include neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with different functions in the immune system.

Q2: What are normal percentage ranges for WBC types?
A: Normal ranges vary but typically: neutrophils 40-60%, lymphocytes 20-40%, monocytes 2-8%, eosinophils 1-4%, basophils 0.5-1%.

Q3: When is differential WBC testing performed?
A: It's performed when infection, inflammation, allergy, or blood disorders are suspected, or as part of routine complete blood count (CBC) testing.

Q4: Can this calculator be used for all WBC types?
A: Yes, the same formula applies to calculate the percentage of any specific white blood cell type relative to the total WBC count.

Q5: How accurate is manual differential counting?
A: Manual counting has some variability; automated cell counters provide more consistent results, but manual review is often used for verification.
