A / G
The ratio of albumin to globulin — useful in evaluating protein status.
What is it
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
A low A/G ratio has been associated with chronic inflammation and certain disease states in research literature.
Reference range
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
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

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