| Principle | Biuret Method using blue cupric complex color for total protein. Albumin is measured by a BCG dye method. Globulin is calculated based on the measured total protein and albumin. Globulin is calculated when total protein and albumin are requested. The calculation is: Total protein minus albumin equals globulin. |

| Interpretation | Total protein variation depends on changes in the major components, albumin and globulins. Albumin is rarely elevated. Causes of decreased levels include: 1. Increased losses: burns, protein losing enteropathies and nephrosis; 2. Decreased synthesis: severe hepatitis or cirrhosis or malnutrition. Globulins are decreased in cachexia, severe combined immunodeficiency states or congenital deficiency states, immunosuppression by chemotherapy or malignancy. Globulins are increased in cirrhosis, chronic inflammatory states, sarcoidosis, collagen vascular diseases and monoclonal gammopathies. |
