Albumin : Globulin Ratio

A / G

The ratio of albumin to globulin — useful in evaluating protein status.

What is it

Albumin : Globulin Ratio — in plain English.

The albumin-to-globulin ratio is calculated from the standard protein panel. It has been studied in research on chronic disease and inflammation.

Why it's measured

What A / G can reveal.

A low A/G ratio has been associated with chronic inflammation and certain disease states in research literature.

Reference range

Where most laboratories draw the standard line.

Standard laboratory reference

1.0 – 2.5 ratio

Reference ranges vary by laboratory. Your individual reference range will appear on your test report and should be interpreted by your physician in the context of your overall health profile.

What results may indicate

Higher vs. lower A / G — at a high level.

Elevated

May be seen with certain genetic conditions.

Lower

Has been associated with chronic inflammation and chronic disease in research literature.

These associations are general. They are not a personal diagnosis or prediction. Discuss your individual results with your physician in the context of your full health profile.
