Normally there is a certain amount of protein in the blood, but there is no protein in the urine. Changes in the total amount of protein in the blood and the appearance of protein in the urine indicate abnormalities in the body.

Protein plays an important role in many activities of the body such as building blocks of many organs, hormones and enzymes, creating colloidal pressure, contributing to maintaining pH balance, protecting the body. A total protein quantitative test will help detect abnormal levels of protein in the body that can be the cause of some diseases.

Protein is made up of 20 amino acids that are essential for the body to build cells and tissues, for body growth, development and health protection. Protein is also a structural component of most parts of the body, creating enzymes and hormones.
