Albumin-to-Globulin Ratio (A/G)
Albumin-to-globulin ratio = albumin / (total protein - albumin), both in g/dL; a lower value is less favorable and interpretation is context-dependent (typical range ~1.1-2.5).

Example
- Serum albumin
- 4.0 g/dL
- Total protein
- 7.0 g/dL
Result: Albumin-to-globulin ratio 1.33 (globulin 3 g/dL) — a lower value is less favorable; interpretation is context-dependent (typical range ~1.1-2.5).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- value
- A/G = albumin / (total protein - albumin). Typical range ~1.1-2.5; a low or reversed ratio (< ~1) flags inflammation, paraproteinemia, or protein loss. A lower A/G is less favorable.
What you enter
- Serum albumin
- Total protein
