Homocysteine blood test: what your result means
Homocysteine measures an amino acid linked to methylation pathways and vascular health. It can be influenced by B-vitamin status.

What does high homocysteine mean?
Higher values may suggest reduced vitamin cofactor availability or increased vascular stress. What counts as high depends on the reference range printed on your lab report, because ranges differ between laboratories.
What does low homocysteine mean?
Lower values are usually not concerning in isolation. What counts as low depends on the reference range printed on your lab report, because ranges differ between laboratories.
Homocysteine units and conversion
Mediki shows homocysteine in µmol/L. Labs may report it in other units; Mediki converts them automatically so results from different labs line up on one chart.
| Unit on your report | Convert to µmol/L | Convert back |
|---|---|---|
| mg/dL, mg/100mL, mg% | 1 mg/dL = 73.98 µmol/L | 1 µmol/L = 0.01352 mg/dL |
| mg/L, µg/mL | 1 mg/L = 7.397 µmol/L | 1 µmol/L = 0.1352 mg/L |

Why track homocysteine over time?
A single homocysteine result is a snapshot. Comparing it with your earlier tests shows whether a value is stable, slowly drifting, or responding to a change in treatment or lifestyle, which is often more useful than one number on its own.
