What this marker measures
The A/G ratio is calculated, not directly measured. It is most informative when read together with albumin, globulin, and total protein.
High or low: what it can mean
High A/G Ratio
A high A/G ratio is uncommon and may be seen with low globulin or relatively high albumin. It is interpreted alongside the rest of the protein panel and the broader clinical picture.

Low A/G Ratio
A low A/G ratio can be seen with chronic inflammation, certain liver conditions, or with elevated globulin from other causes. Diagnosis usually requires confirmation and clinical context.
