The albumin/globulin (A/G) ratio compares the levels of albumin and globulin proteins in your blood. This ratio helps evaluate liver function, kidney function, and immune system health.
Category: Metabolic Panel
Also known as: a/g ratio, albumin/globulin ratio, ag ratio, albumin globulin ratio
Reference range: 1.1–2.5 ratio (Source: ABIM)
Standard unit: ratio
High values may indicate
A high A/G ratio is generally not clinically significant but may indicate underproduction of globulins, as seen in some genetic conditions or immune deficiencies.
Low values may indicate
A low A/G ratio may indicate liver disease, kidney disease, autoimmune conditions, or multiple myeloma.
