Patient Friendly Summary

A raised WBC count usually means your body is actively fighting something. The differential count (neutrophils, lymphocytes, etc.) gives your doctor more clues about the likely cause.

What this test means

White blood cells are your immune system's soldiers. Their count rises and falls with infections, inflammation, stress, and some medicines.

Why it is done

It is done for fever, suspected infections, unexplained body pain, and to monitor treatments that can affect immunity.

Understanding your value

If your value is high

A high count can be seen in bacterial infections, inflammation, stress, or after steroid medicines.

If your value is low

A low count can be seen in viral infections (including dengue), some vitamin deficiencies, or as a medicine side effect.

About the normal range

Adult ranges are commonly around 4,000–11,000 cells/µL, but lab ranges vary — use the range on your report.

When to consult a doctor

See a doctor if the count is flagged abnormal with fever, or promptly if you have high fever with severe weakness or repeated vomiting.
