1 Parameters Included

The Homocysteine Quantitative, Serum test measures the levels of homocysteine in the blood. Homocysteine is an amino acid that is produced during the metabolism of another amino acid, methionine. While homocysteine is normally present in the body, elevated levels (a condition known as hyperhomocysteinemia) can be a risk factor for various health conditions, particularly those related to the heart and blood vessels.

How is the Test Performed?

The test is done using a blood sample, usually drawn from a vein in your arm. The sample is then analyzed to determine the concentration of homocysteine in your blood.

Normal and Abnormal Results

• Normal range: The normal range for homocysteine can vary slightly depending on the laboratory, but it is typically in the range of 5 to 15 micromoles per liter (µmol/L).
• Elevated levels: Higher-than-normal levels of homocysteine are considered hyperhomocysteinemia and may be classified as:
  • Mild: 15 to 30 µmol/L
  • Moderate: 30 to 100 µmol/L
  • Severe: >100 µmol/L Elevated homocysteine levels may be associated with a variety of health conditions, particularly cardiovascular problems.
