Clinical Significance

Protein, Total and Albumin - The major proteins seen in the serum are albumin and globulin-the latter being primarily alpha 1 and alpha 2 globulin, beta globulin and gamma globulin. Albumin accounts for more than 50% of the total serum proteins. The albumin to globulin (A/G) ratio has been used as an index of disease state, however, it is not a specific marker for disease because it does not indicate which specific proteins are altered. The normal A/G ratio is 0.8-2.0. The A/G ratio can be decreased in response to a low albumin or to elevated globulins. Total globulins may be increased in some chronic inflammatory ...
