Serum Homocysteine

A Serum Homocysteine test determines the levels of homocysteine, a naturally occurring amino acid in your blood. Elevated homocysteine can damage the lining of arteries, encouraging blood clotting. This may raise your risk for coronary artery disease, heart attacks, blood clots, and strokes. High levels of homocysteine are also associated with low levels of vitamins B6, B12, and folate, as well as renal disease
