Homocysteine (Hcy) is a thiol-containing amino acid produced by the intracellular demethylation of methionine. Total homocysteine (tHcy) represents the sum of all forms of Hcy (including forms of oxidized, pro-tein bound and free).

Elevated level of tHcy has emerged as an important risk factor in the as-sessment of cardiovascular disease. Excess Hcy in the bloodstream may cause injuries to arterial vessels due to its irritant nature, and result in in-flammation and plaque formation, which may eventually cause blockage of blood flow to the heart.
