Homocysteine Test
This test measures the level of homocysteine in your blood, which is important because high levels can increase your risk for heart disease. It's often used together with a methylmalonic acid (MMA) test to check for vitamin B12 (cobalamin) and folic acid deficiencies. These deficiencies can lead to anemia and are also checked when someone has macrocytosis, a condition where red blood cells are larger than normal.
What patients is this test right for?This test may be recommended if you are at risk for heart disease or have symptoms that suggest a vitamin B12 or folic acid deficiency.
Symptoms of Vitamin B12 or Folic Acid Deficiency:• Tiredness
• Weakness
• Pale or yellowish skin
• Heart palpitations
• Shortness of breath
• Loss of appetite
• Weight loss
• Confusion or memory problems
What type of sample is required for this test?1 mL serum.
A blood draw is needed.
Test Resources:For more information, consult your healthcare provider.
Additional test information
An elevated concentration of homocysteine is an independent risk factor for cardiovascular disease. When used in conjunction with methylmalonic acid (MMA), these tests are useful to diagnose and monitor vitamin B12 (cobalamin) and folic acid deficiency and are often useful in evaluating macrocytosis (an elevated MCV, an erythrocytic index).
Collection and processing
- Sample type: Serum
- Fasting: No
- Estimated laboratory processing: Results should be available in 2 – 5 business days after the sample is collected
How Sunridge uses laboratory information
Sunridge considers the medical question, symptoms, history, medications, prior results, and whether the finding could change care before recommending testing. A laboratory result is not interpreted in isolation and does not establish a diagnosis by itself.
Before requesting this test
Availability, collection requirements, eligibility, and processing estimates can change. Sunridge reviews each request and, when appropriate, creates the order through Fullscript. Follow the current instructions supplied with the approved order.
