How to read a Complete Blood Count (CBC) report
June 2, 2026 · 5 min read
A Complete Blood Count, or CBC, is one of the most commonly ordered lab tests — and one of the most confusing to read at a glance, because a single report can list a dozen or more values. Here's what the core groups actually mean.
Red blood cells
Haemoglobin and Haematocritboth reflect how much oxygen-carrying capacity your blood has. Low values are commonly associated with anaemia; the specific cause needs a clinician's interpretation, not a single number. RBC Count, MCV, MCH, and MCHC describe the size and haemoglobin content of individual red cells, and are often used together to narrow down what type of anaemia might be present.
White blood cells
WBC Count(or Total Leukocyte Count) is the headline number for your immune system's cell population. The White Cell Differential breaks this down further — neutrophils, lymphocytes, monocytes, eosinophils, and basophils — each associated with different immune functions.
Platelets
Platelet Count reflects your blood's clotting capacity. Related values like MPV (mean platelet volume) describe platelet size, which can add context to an abnormal count.
Why tracking matters
A single CBC is a snapshot. The same value can mean different things depending on whether it's trending up, down, or holding steady compared to your own history — which is exactly what Enaro is built to show you automatically, report after report.
