A/G Ratio

Serum proteins are primarily albumin (50-60%, produced by the liver), but also include globulins, and other proteins. 

Serum proteins:

  • Maintain water balance in the blood through osmotic pressure
  • Transport blood components and nutritional elements
  • Help the immune system
  • Help with coagulation

Although albumin is made exclusively in the liver, globulins are produced in many sites throughout the body. Thus, whether total protein is normal, elevated, or low, a decrease in the A/G ratio often indicates the presence of impaired liver function.
