Albumin Globulin Ratio Calculator A G Ratio

What Is the Albumin-to-Globulin Ratio?

The albumin-to-globulin (A/G) ratio compares two major blood protein groups. It helps evaluate liver function, kidney disease, and inflammatory conditions. Related tools: Albumin Creatinine Ratio Calculator and Corrected Calcium Calculator.

$$A/G\ ratio = \frac{Albumin}{Globulin}$$

When globulin is not reported directly, calculate it as total protein minus albumin. Normal range is typically 1.0 to 2.0.

What does a low A/G ratio mean?

A ratio below 1.0 may indicate increased globulin from chronic inflammation, liver disease, or multiple myeloma.

What does a high A/G ratio mean?

A ratio above 2.0 may reflect globulin deficiency or relatively elevated albumin, though it is less common clinically.

Can I use total protein instead of globulin?

Yes. Subtract albumin from total protein to estimate globulin when only those two values are available on your lab report.

What are normal lab values?

Typical adult reference ranges are albumin 3.5–5.0 g/dL, total protein 6.0–8.3 g/dL, and globulin 2.0–3.5 g/dL.

Should I diagnose based on A/G ratio alone?

No. The ratio is one piece of a broader clinical and laboratory evaluation interpreted by your healthcare provider.
