Serum total protein

Serum total protein, also known as total protein, is a clinical chemistry parameter representing the concentration of protein in serum.^[1] Serum contains many proteins including serum albumin, a variety of globulins, and many others. While it is possible to analyze these proteins individually, total protein is a relatively quick and inexpensive analysis that does not discriminate by protein type.

The traditional method for measuring total protein uses the biuret reagent, but other chemical methods such as dye-binding and refractometry are now available. The measurement is usually performed on automated analysers along with other laboratory tests.^{[citation needed]}
