Why This Test

Homocysteine testing promises cardiovascular insights—but the evidence for treatment is more complicated than the headlines suggest. Popular in functional medicine circles, homocysteine is linked to MTHFR gene variants and B-vitamin status. While elevated levels are associated with cardiovascular risk, the value of treatment remains debated.

Common Questions

Yes, fasting for 8-12 hours ensures accurate homocysteine measurement.

MTHFR is a gene involved in folate metabolism. Common variants can affect how you process B-vitamins and may influence homocysteine levels.

Homocysteine is the functional marker - it shows whether your B-vitamin metabolism is working well, regardless of which genetic variants you carry.

Results are typically available in 3-5 business days via your dashboard.
