Homocysteine

Homocysteine is an amino acid produced during protein metabolism. Elevated blood homocysteine, called hyperhomocysteinemia, is an independent risk factor for cardiovascular disease, stroke, and blood clots. High levels may indicate deficiencies in vitamins B12, B6, or folate, kidney disease, or genetic factors affecting homocysteine metabolism. This test helps identify cardiovascular risk and vitamin deficiencies. Lowering homocysteine through B-vitamin supplementation or dietary changes may reduce heart disease and stroke risk.
