Total Protein
A total protein test measures the sum of all types of proteins in the blood.
Proteins are fundamental to the functioning of the body. The two main types of proteins found in the blood are albumin and globulins.
Measuring the total protein level as well as the ratio of albumin to globulin can help detect several kinds of health problems, including liver and kidney disease as well as nutritional deficiencies.
In many cases, total protein is included with other measurements using the same blood sample in a test like a liver panel or comprehensive metabolic panel. Whether tested alone or in a panel, total protein and the albumin-to-globulin ratio (A/G ratio) can be involved in the diagnosis, screening, and monitoring of a range of health conditions.
