Clinical Notes

A total protein test measures the sum of all types of proteins in the blood. Proteins are fundamental to the functioning of the body. Too much or too little protein can reflect conditions including liver or kidney disease, infection, inflammation, malnutrition, and cancer. In many cases, the total protein measurement and A/G ratio are included as part of broader tests, such as the liver panel or comprehensive metabolic panel, that offer further information about possible health conditions.
