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.

When it's measured

When A / G is typically run.

Calculated from standard protein panel.

Related markers

Why is Albumin : Globulin Ratio measured?

It's one of the markers used to build a fuller picture of your health. On its own it tells you very little, so it's most informative when reviewed alongside related markers.

How is Albumin : Globulin Ratio tested?

It's measured from a standard blood draw at Quest or LabCorp. Albumin : Globulin Ratio is one of the markers included in the OPTML Apex Panel, where your results are read across systems and reviewed by a U.S.-licensed physician.

What should I do with my Albumin : Globulin Ratio result?

Reference ranges vary by laboratory, and a single value rarely tells the whole story. Review your result with a physician in the context of your other markers, symptoms, and history.
