Vitamin B12 and folic acid blood help maintain healthy homocysteine levels. High levels can be an indicator of cardiovascular disease. In addition, doctors may use the results of this test to help diagnose central nervous system disorders, anemia and malabsorption syndromes.
Vitamin B12 and folic acid blood testing help doctors diagnose central nervous system disorders, anemia, and malabsorption syndromes. B12 and folic acid also play an important role in energy level, muscle strength, and memory. Because B12 and folate are derived solely from dietary intake, such as egg yolks, beef, poultry, and fish, many people are deficient in these important vitamins.
Instructions
Fasting is not required for this test. Stay hydrated and take your medications as prescribed. Avoid B12 and folate containing supplements for 12 hours preceding the test. The MMA test can provide more information on B12 status as high levels of MMA are a more sensitive marker of vitamin B12 deficiency.
Note
This test is available to minor test recipients over 5 years of age with parental consent.
