Why The Test Is Performed Total protein is a rough measure of serum protein . Protein measurements can reflect nutritional state, kidney disease , liver disease , and many other conditions. If total protein is abnormal, further tests must be performed to identify which protein fraction, and then which specific protein, is abnormal.
Proteins are important constituents of all cells and tissues.
Proteins are made from amino acids . A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the tourniquet is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding . Cotton or a bandage may be applied to the puncture site if there is any continued bleeding.
