The most common protein in the blood is albumin, which prevents fluid from leaking and carrying substances through the body.Īlmost all of the other proteins in the blood are globulins, formed by the immune system and by the liver. Proteins are vital to the functioning of virtually all parts of the body.

It can also be part of panel tests to check liver and kidney health when taking medications that can affect these organs.Ī total protein test measures the combined sum of all the different blood proteins in the liquid portion of blood (plasma or serum). Total protein may be measured in repeat tests at regular intervals if you have known liver or kidney problems. Monitoring is testing used to follow your condition over time or in response to treatment.Panel tests, including total protein, for example, may be part of routine checkups for people who have a higher risk of developing liver or kidney disease to hopefully detect problems at an earlier stage. Screening involves tests that look for health problems before they have caused any symptoms.Diagnosis happens after you have symptoms and includes tests that work to determine what is causing those symptoms.This testing can be utilized as part of diagnosis, screening, and/or monitoring: The A/G ratio can also be used to look for signs of an underlying health issue. In addition to the total protein level, testing can determine the ratio between types of proteins known as albumin and globulins. 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. Too much or too little protein can reflect conditions including liver or kidney disease, infection, inflammation, malnutrition, and cancer. The purpose of a total protein test is to check the levels of proteins in the blood.
