Albumin-to-Globulin Ratio Calculator

What is the Albumin-to-Globulin Ratio?

The Albumin-to-Globulin Ratio (A/G Ratio) is a calculated value that compares the levels of albumin and globulin in the blood. Albumin is a protein produced by the liver, while globulins include a group of proteins involved in immunity and other vital functions.

Why is the A/G Ratio Important?

The A/G Ratio provides important insights into overall health, especially liver function, immune system activity, and nutritional status. An abnormal ratio may indicate conditions such as liver disease, kidney disease, or immune disorders.

How is the A/G Ratio Calculated?

The ratio is calculated using the formula:

Globulin = Total Protein - Albumin
A/G Ratio = Albumin ÷ Globulin

If the inputs are in different units, they are first converted to ensure consistency:

Albumin (g/dL) = Albumin (g/L) ÷ 10
Total Protein (g/dL) = Total Protein (g/L) ÷ 10

Example Calculation

Inputs:
  Albumin: 42 g/L
  Total Protein: 70 g/L

Conversion:
  Albumin (g/dL) = 42 ÷ 10 = 4.20
  Total Protein (g/dL) = 70 ÷ 10 = 7.00

Calculation:
  Globulin = 7.00 - 4.20 = 2.80
  A/G Ratio = 4.20 ÷ 2.80 = 1.50
