Total Protein + Albumin:Globulin (A/G)

There are two major proteins in the blood. Albumin helps keep blood from leaking out of blood vessels and moves other important substances throughout the body, while globulins help fight infection and move nutrients throughout the body. The A/G ratio compares the amount of albumin in your blood to the amount of globulin. This test helps diagnose kidney disease, liver disease, or nutritional problems.
