Homocysteine Test

$79

Discover your homocysteine level with a simple blood test

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.

What's Tested

Homocysteine

Homocysteine is an amino acid produced in the body through metabolism. Normally, the body breaks down homocysteine with the help of vitamins B6, B12 and B9 (also known as folate). An elevated homocysteine level could suggest a vitamin deficiency and may be associated with increased cardiovascular risk.

❮ ❯

Worried about your heart health?

When homocysteine is not broken down properly, it can damage the lining of your arteries and make the blood clot more easily, increasing your risk of cardiovascular disease. Understanding your homocysteine level can help you assess whether you have a higher risk of a heart attack, stroke, coronary artery disease (CAD) and more.²

Better understand your cardiovascular risk

Homocysteine can be considered an independent risk factor for cardiovascular disease. If you have already been diagnosed with heart disease or have risk factors, an elevated homocysteine level may indicate another risk factor for heart and blood vessel disease.¹

Monitor your homocysteine levels over time

For people who have cardiovascular disease or are at risk of developing it, testing can help you track changes in homocysteine levels so that you can keep tabs on your heart health and have informed discussions with your healthcare provider.²

FAQ

Anyone interested in assessing or monitoring cardiovascular risk factors including those with symptoms such as dizziness, fatigue, weakness or heart palpitations may want to consider a homocysteine test. An elevated homocysteine level could indicate a vitamin deficiency and may be associated with a higher risk of cardiovascular disease. Periodic testing can also track changes in homocysteine levels.
High homocysteine levels can be caused by several factors including: vitamin deficiencies, genetic factors, medical conditions such as kidney or thyroid disease, certain medications, and lifestyle factors including smoking and excessive alcohol consumption. Homocysteine levels also tend to increase with age.

If you have questions about your homocysteine level, it is best to discuss them with your healthcare provider for personalized guidance and further evaluation.
If you have a high homocysteine level, which is also sometimes referred to as hyperhomocysteinemia, your healthcare provider may recommend that you take supplements of vitamin B6, vitamin B12 and folic acid (the human-made form of folate, also known as vitamin B9). It is important to consult with your provider to determine if supplementation is appropriate, and at what dosage, as too much vitamin B6, vitamin B12 and folic acid can have negative effects.
