Albumin-to-globulin ratio
—
Laboratory protein ratio; no diagnostic category is assigned
Normalized albumin: — g/dL · globulin: — g/dL · total protein: — g/dL
About
The albumin-to-globulin (A/G) ratio compares serum albumin with the measured or calculated non-albumin protein fraction. It is laboratory arithmetic, not a stand-alone diagnosis.
Formula
Interpretation
What the result represents: A unitless comparison of albumin with globulin.
Input units: Albumin and globulin or total protein may each be entered in g/dL or g/L; each is explicitly converted to g/dL.
Worked example: Albumin 4.0 g/dL and globulin 2.5 g/dL gives 1.60. Albumin 4.0 and total protein 6.5 gives the same result.
Applicable population: Laboratory reference use when serum protein measurements from a compatible panel are available.
Interpretation limitations: Reference intervals depend on laboratory method and population. Interpret the ratio with the absolute albumin, globulin, and total protein values; it does not by itself identify liver disease, kidney disease, nutrition status, inflammation, or immunoglobulin disorders.
