Homocysteine Test

This profile measures homocysteine, a natural by-product of processing protein in your body. Normally, it is broken down with the help of vitamins B12, folate (B9), and B6. If levels rise, this can signal vitamin deficiencies, kidney or thyroid problems, or other underlying health issues.

There are no symptoms of raised homocysteine — only a blood test can reveal it. High levels have been linked with an increased risk of:

• Heart disease
• Stroke
• Memory decline and dementia
• Osteoporosis and fractures
• Pregnancy complications
• And many other associations continue to emerge

Because raised homocysteine is most often due to low vitamin B12 or folate, it is best interpreted alongside tests for these vitamins. If your vitamin levels are low, further checks may be needed to understand why (for example, digestive causes, medication effects, or diet), and a clinician can guide safe treatment with supplements if required.

While you cannot always control homocysteine levels directly, you can:

• Ensure healthy levels of vitamins B12, folate, and B6 by eating a diet rich in these vitamins
• Maintain an active lifestyle
• Avoid smoking and limit alcohol and coffee intake
• Work with your healthcare provider on further tests and tailored advice

This profile is especially valuable if you have a personal or family history of heart disease, stroke, or vitamin deficiencies. However, anyone may benefit from understanding their homocysteine status to better guide their long-term health.
