Total serum globulin consists of individual globulin fractions called alpha 1, alpha 2, beta and gamma fractions. Thus the total globulin level is greatly affected by increases or decreases in one or more of these fractions. They are produced in the liver, the retoculoendothelial system, and other tissues. The function of globulins is to transport substances in the blood. They also make up the antibody system, clotting proteins and complement.
- As inflammatory, degenerative, or infectious processes are associated with an increased production of antibodies, measuring the total serum globulin is a useful way to assess these processes.
- Total globulin, along with subjective indicators, can also help to confirm an underlying digestive problem of an inflammatory or infectious nature.
- Protein electrophoresis is a method widely used to identify the specific globulin that is responsible for the total serum globulin increase or decrease.
- No specific preparation is required.
