White Blood Cell Count
What It Is
WBC count measures the total number of white blood cells, the primary cells of the immune system.
Why It Matters
White blood cell count is a fundamental marker of immune function and helps detect infections, inflammation, and blood disorders.
If Levels Are High
Elevated WBC may indicate infection, inflammation, stress, or leukaemia.
If Levels Are Low
Low WBC increases infection risk and may indicate bone marrow problems or autoimmune conditions.
Preparation
No special preparation required.
How Often to Test
Annually as part of a full blood count.
