Overview of Homocysteine
What is Homocysteine?
This test is ordered to determine if you have a vitamin B12 or folate deficiency; to determine if you are at increased risk of heart attack or stroke; as a part of newborn screening to help diagnose a rare inherited disorder called homocystinuria.
The sample type collected for Homocysteine is: Blood
Preparation for Homocysteine
- Do not eat or drink anything other than water for 8-12 hours before the test.
Why Get Tested for Homocysteine?

- To determine your risk of heart disease like heart attack or stroke
- When an infant or child has signs or symptoms of homoystinuria
What Results of Homocysteine mean?
- Increased levels of homocysteine may be seen in vitamin B12 or folate deficiency. It should be confirmed by other tests for Vitamin B12 or folate
- Latest studies also suggest that raised homocysteine levels may be associated with increased risk of cardiovascular disease like heart attack or stroke
- In newborn testing, greatly increased concentrations of homocysteine in urine or blood means that it is quite likely the infant is suffering from homocystinuria
