Reading these numbers in context
Reference ranges describe the central 95 % of a healthy reference population — 5 % of perfectly healthy people fall outside any given range by definition. A single mildly abnormal value is rarely meaningful on its own. blood-test.life always interprets values together with related biomarkers before flagging.

Hemoglobin
HGB
Oxygen-carrying protein in red blood cells. Low hemoglobin is the defining marker of anemia.
Hematocrit
HCT
Percentage of blood volume occupied by red blood cells. Moves in parallel with hemoglobin.
White Blood Cell Count
WBC
Total count of infection-fighting white cells. Subtypes (neutrophils, lymphocytes) carry far more diagnostic weight.
Platelets
PLT
Cell fragments responsible for blood clotting. Critical for bleeding-risk assessment.
