Homocysteine: what this test measures

This test measures the level of homocysteine in your blood. It is influenced by vitamin B12, folate, and vitamin B6 status, which are needed to metabolise homocysteine.

Homocysteine: why this value matters

Elevated homocysteine may be associated with cardiovascular disease, blood clots, and cognitive decline. It can also indicate B-vitamin deficiencies. Consult your healthcare provider for personalised guidance.

Homocysteine: how to prepare

  1. Preferably fasting

    Recommended

    Coming fasting gives a slightly cleaner value, but it is not required. If it suits you, eat nothing from 22:00 the evening before and drink only water.

  • Water is always fine. Drink as usual beforehand, it makes the draw easier.
  • Take your usual medication, unless your own doctor told you otherwise.

Homocysteine: when is testing worthwhile?

Testing may be recommended if you have a family history of cardiovascular disease, unexplained blood clots, or symptoms of B-vitamin deficiency.

Homocysteine: symptoms of a high or low value

Low Levels

Low homocysteine levels are generally considered favourable and are not associated with health concerns.

High Levels

High homocysteine itself may not cause noticeable symptoms but is associated with increased risk of cardiovascular events, blood clots, and cognitive issues over time.

Homocysteine: what to do about an abnormal value

Female

If Low

Low homocysteine is favourable and indicates low cardiovascular risk.

If High

Elevated homocysteine increases cardiovascular risk. Consider B vitamins (B12, B6, folate).

Homocysteine: lifestyle and this value

Ensure adequate intake of folate, vitamin B12, and vitamin B6 through foods such as leafy greens, legumes, eggs, and fortified cereals. Limiting alcohol and maintaining a balanced diet may help manage homocysteine levels.

Homocysteine: frequently asked questions

How can I lower my homocysteine?

Adequate intake of folate, B12, and B6 may help lower homocysteine. Discuss supplementation and dietary changes with your healthcare provider.

Is homocysteine a reliable heart disease marker?

Elevated homocysteine is considered an independent risk factor, though it is best evaluated alongside other cardiovascular markers. Consult your healthcare provider.

Can genetics affect homocysteine levels?

Yes, certain genetic variations (such as MTHFR) can affect how your body processes homocysteine. Your healthcare provider can advise on testing and management.
