B12 Status Panel
Item Catalog Number: LC100002
This panel contains the following tests:
- Vitamin B12 (cyanocobalamin)
- Urinary Methylmalonic Acid (MMA)
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.
Methylmalonic Acid (MMA) found in the urine 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.
Fasting is preferred when taking this panel. Take all medications as prescribed. Do not take your supplements the morning of the test.
