Homocysteine is an amino acid normally found in small amounts in the blood. However, high levels of homocysteine in the blood may promote plaque buildup in blood vessels that may, over time, lead to serious cardiovascular problems.
High levels of homocysteine in the blood may be associated with an increased risk of atherosclerosis and subsequent coronary artery disease.
Homocysteine levels can be elevated by other factors such as family history, age and gender. Homocysteine can be elevated by some medications and by chronic kidney disease.
Strong family history of heart disease, high cholesterol levels, Vitamin B12/ folic acid deficiency
Fasting for 12 hours is a must.
