Chemical compound

Bromsulfthalein (also known as bromsulphthalein, bromosulfophthalein, and BSP) is a phthalein dye used in liver function tests. Determining the rate of removal of the dye from the blood stream gives a measure of liver function. The mechanism by which the liver detoxifies BSP is to attach it to glutathione which is the body’s master antioxidant.
