Albumin/Globulin Ratio

Albumin/Globulin ratio (A/G ratio) test determines the levels of albumin proteins in comparison to globulin proteins present in the blood serum. Albumins are made in the liver and carry medicine and hormones throughout the body. Globulins are made by the liver and white blood cells, which act as transporters and fight infections. Blood usually contains slightly more albumin than globulin. A/G ratio between 1.1 and 2.5 is considered normal. A low A/G ratio indicates an autoimmune disease, liver inflammation or tumor in bone marrow. A high A/G ratio signifies liver, kidney and intestine disease or leukemia.

The test helps in diagnosing liver and kidney problems or nutritional deficiency. Symptoms like fatigue, loss of appetite, weight loss, swelling in limbs, jaundice or blood in urine indicate abnormality.
