Description
A Homocysteine Blood Test measures the amount of homocysteine in your blood, an amino acid produced when your body processes protein. Normally, homocysteine is converted into other useful substances with the help of vitamins B6, B9 (folate), and B12. Elevated levels can signal health concerns that may require attention.
Why It's Done
- Check vitamin levels: High homocysteine may indicate a deficiency in B6, B9, or B12.
- Assess genetic risk: Detect rare inherited conditions like homocystinuria, which can affect bones, vision, and blood clotting.
- Evaluate heart health: Elevated homocysteine can damage blood vessels and increase the risk of heart attack, stroke, or blood clots.
- Monitor kidney health: Impaired kidney function can also raise homocysteine levels.
Who Should Consider This Test
- Individuals with a personal or family history of heart disease or stroke
- Patients with unexplained blood clots or recurrent thromboembolic events
- Those suspected of vitamin B deficiencies
- Individuals with a history of kidney disease
Test Details
- Specimen: Blood sample
- Fasting: Not required
- Results: Typically, normal levels range from 5–15 µmol/L. Elevated levels may indicate vitamin deficiency, genetic conditions, or increased cardiovascular risk.
This simple blood test can provide valuable insights into nutritional status, inherited disorders, and heart health, helping you and your healthcare provider take proactive steps to prevent complications.
