Homocysteine is an amino acid (building block of protein) produced in the body. Normally, homocysteine levels are low, because homocysteine is typically broken down by vitamins B6, B12 and B9 (also known as folate).¹
High homocysteine levels can be associated with increased risk of several conditions, including cardiovascular disease, blood clots and other blood vessel disorders.²
This trusted homocysteine blood test measures the level of homocysteine in your blood. It should not be used for the diagnosis of a vitamin B9 or B12 deficiency.
