Albumin/Globulin Ratio (A/G)
The albumin-to-globulin ratio compares liver-made albumin with immune and transport globulins and is calculated from the total protein and albumin measurements. Low ratios can indicate chronic inflammation, autoimmune disease, liver disease, or multiple myeloma, while high ratios suggest low antibody production. It helps direct further workup such as serum protein electrophoresis.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for Albumin/Globulin Ratio (A/G). How we verify ranges.
- No stated targetNo separate optimal establishedLow ratios track inflammation or protein loss
- Lab reference interval1.1-2.5What a lab report flags against. A lab interval is not an optimal target.

Why Albumin/Globulin Ratio (A/G) matters
Compares albumin (made by liver) to globulins (immune proteins). Abnormal ratios may indicate liver disease, kidney disease, immune disorders, or chronic inflammation. Helps narrow down the cause of protein abnormalities.
