This panel includes tests for blood levels of vitamin B12, folate and methylmalonic acid (MMA), which aid in the diagnosis of central nervous system disorders and help guide supplementation levels.
This panel contains the following tests:
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.
Primary food sources for B12 and folate include egg yolks, beef, poultry, and fish; which can leave people who do not consume these food sources, such as vegetarians, deficient in these important vitamins.
Methylmalonic Acid (MMA) is often associated with the early stages of B12 deficiency. MMA may be ordered along with a homocysteine test, when a vitamin B12 deficiency is suspected. An MMA test also may be ordered as a follow-up to an elevated homocysteine level.
Instructions
An 8 to 12 hour fast is required for this blood test. However, drink plenty of water and take your medications as prescribed. Avoid B12 and folate containing supplements for 12 hours preceding the test
