Understanding the test
What does the Homocysteine test measure?
Also called Cardiac / Metabolic Amino Acid
A clinician may request homocysteine to investigate a possible B-vitamin problem or clarify related results. It is influenced by more than dietary intake.
When it may be requested
Investigating selected metabolic questions
Homocysteine can rise when folate or vitamin B12 metabolism is disrupted.
Interpreting a raised level
Kidney function, medicines and related vitamins can help the clinician decide on further testing.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
A fasting morning sample with plain water is requested. Report folate, B6 or B12 supplements and confirm their timing with the clinician before changing your usual routine.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
An elevation is not specific to a single deficiency and does not establish cardiovascular disease. Kidney function and more specific vitamin measurements may help explain it.
What can affect it
- An increase is not specific to one deficiency or a single disease.

Patient questions
Before you book
Does elevated homocysteine tell me which vitamin is deficient?
No. Folate, vitamin B12 and other factors affect it. Your clinician may request more specific measurements before recommending treatment.
Why must I fast for this test?
Food can affect the measurement. Follow the fasting instructions for this order so that your clinician can compare the result with a sample taken under similar conditions.
Is homocysteine routinely checked after an unexplained blood clot?
No. A raised result alone cannot explain why a clot occurred. Homocysteine is generally left out of routine thrombophilia panels. A clinician may request it for a specific reason, such as signs of the rare inherited condition homocystinuria or an investigation into vitamin deficiency.
