How our AI interprets it
Our AI lab test analyzer always cross-checks hemoglobin with MCV, MCH, ferritin, and reticulocyte counts before flagging anemia type.
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.
