What are the Grades of Leukopenia?

Leukopenia means low white blood cell (WBC) count, which weakens your immunity. But did you know it's graded by severity?

Grade 1: Mild Leukopenia

WBC count: 3000–4000/mm³

Often has no symptoms and may be picked up during routine blood tests.

Grade 2: Moderate Leukopenia

WBC count: 2000–2999/mm³

May lead to frequent infections, fatigue, and slower wound healing.

Grade 3: Severe Leukopenia

WBC count: 1000–1999/mm³

High risk of infections; urgent intervention is usually needed.

Grade 4: Very Severe Leukopenia

WBC count: <1000/mm³

A life-threatening condition with a critically weakened immune system.

Why Grades Matter?

The lower the grade, the higher your risk of infections, inflammation, and complications. Early diagnosis is key.
