Albumin by Ray Sahelian, M.D. Serum Albumin

Albumin is the term for a group of proteins making up close to 60% of the protein in blood plasma. Albumin proteins are important in regulating blood volume by maintaining the osmotic pressure of the blood compartment. Albumin proteins are important for transporting fatty acids, thyroid hormones, some steroid hormones, and other substances in the bloodstream.

Albumin and stroke
