Albumin+Globulin+AG Ratio

This test calculates the ratio between albumin and globulin proteins in the blood to evaluate liver function, kidney function, and nutritional status.

It helps diagnose liver and kidney disease, immune disorders, and certain cancers. It may also be part of a general health evaluation.

A blood sample is collected and analyzed to determine total protein, albumin, and globulin levels. The ratio is then calculated.

An abnormal A/G ratio could indicate liver disease, autoimmune conditions, or protein loss. The specific interpretation depends on other lab values.

Fasting may be required in some cases. Follow your doctor’s instructions.
