Indicator Explainer
Beta-2-Glycoprotein 1
Beta-2-glycoprotein 1 (345 aa, ~38 kDa) is encoded by the human APOH gene. This protein is involved in binding to phospholipids, glycosaminoglycans and other negatively charged substances.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
