how is globulin total tested?
Globulin proteins include enzymes, antibodies, and more than 500 other proteins. The ratio of albumin to globulin (A/G ratio) is calculated from values obtained by direct measurement of total protein and albumin. It represents the relative amounts of albumin and globulins.
This test measures the total amount of the various types of proteins in the liquid (serum or plasma) portion of the blood. Two classes of proteins are found in the blood, albumin and globulin. Albumin makes up about 60% of the total protein.
