Total Protein(TP) Determination Reagent is an in vitro diagnostic quantitative test kit. This test is used for diagnosis liver or kidney disease. Proteins are one of the building blocks of every cell. They also play an important role in many biological processes. They are essential for growth and development, nutrient and hormone transport, and immune function. Normally, albumin makes up for slightly more than half of the proteins in the blood (serum, the liquid part of the blood), and the remainder of the protein count are the globulins.
