Why homocysteine is tested<\/h2>\n

Homocysteine is an amino acid produced in the body from methionine. Under normal conditions, it is quickly metabolised with the help of vitamins B12, B6 and folic acid. When these are deficient or metabolism is impaired by a genetic condition, homocysteine accumulates in the blood and damages the lining of blood vessels. Elevated levels are associated with a higher risk of atherosclerosis, heart attack, ischaemic stroke and venous thrombosis.<\/p>\n

In practice, the test has two main uses: as a sensitive marker of vitamin B12 and folate deficiency (a normal fasting result largely rules out B12 deficiency), and as an additional indicator of cardiovascular risk in people whose disease is not explained by conventional risk factors.<\/p>\n
