This is a blood test in which homocysteine is measured. Elevated levels of homocysteine often indicate risk factors for heart disease and blood vessel disease. Other risk factors are hardening of the arteries or diseases of other vessels of the body. This test is often done when there has been an unexplained problem with hardening of the arteries or a strong family history of this at a very young age. A deficiency of vitamins B6, B12, or folate are also common causes of elevated levels of homocysteine.
PREPARATION FOR TEST
A 10-12 hour fasting period is required prior to the testing.
Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.
