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.

AST/ALT ratio (De Ritis) > 2 suggests alcoholic liver disease. Alkaline Phosphatase ALP Enzyme from liver, bone, intestine, and placenta. Rises in biliary obstruction or bone turnover.
