Complete Blood Count (CBC)Reported in ×10³/µLWhite blood cell count (WBC)
The total number of white blood cells in a sample. It is the headline immune-cell count, read together with the differential.
What it measures
White blood cells circulate looking for infection, inflammation, and damaged tissue. The WBC adds every type together: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. A single total can rise because one type surged, so the differential underneath it tells you which cells moved.
Why it is on the panel
It is the starting point for “is the immune system responding?” A fever, a new medicine, physical stress, and many chronic conditions can all move this number. On a preventive panel it is also a baseline you can compare next time.
How to read it
Read the total, then the absolute counts for neutrophils and lymphocytes. A normal total can hide an abnormal mix, and an abnormal total is easier to understand once you know which cell type changed.
When it runs higher
A higher count is common with bacterial infection, inflammation, cigarette smoking, corticosteroids, and the physical stress of illness. Very high counts are uncommon on a screening panel and deserve a clinician’s look, especially if they persist.
When it runs lower
A lower count can follow a viral illness, some medicines, an autoimmune condition, or a problem with how the bone marrow is producing cells. How low it is, and which cell type is low, matters more than the total alone.
How to use this page
This page explains what the measurement is for. It is educational. Your Healiam report includes the reference interval for your age and sex, and a clinician reads that result with your history, medicines, and the rest of the panel. Talk with a clinician before changing diet, supplements, or treatment because of a number on a report.
