Indicator Explainer
Albumin
A family of globular proteins found in many plant and animal tissues that tend to bind a wide variety of ligands. Albumin is the main protein in blood plasma. Low serum levels occur in conditions associated with malnutrition, inflammation and liver and kidney diseases.
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.
