What Is This Test?

The Differential Leucocyte Count shows the percentage (and absolute numbers) of each type of white blood cell — neutrophils, lymphocytes, monocytes, eosinophils and basophils.

Why this test is performed?

The pattern helps your doctor tell what kind of problem is likely — e.g., bacterial infection (high neutrophils), viral infection (high lymphocytes) or allergy/worms (high eosinophils).

Who should take this test?

Tiredness, weakness, pale skin, fever, frequent infections, easy bruising or bleeding; routine health check-ups.

Test Preparation

No fasting needed.
