Is there a urine test for vitamin deficiency?

Is there a urine test for vitamin deficiency?

Yes, there is a urine test. The test measures the amount of a substance called methylmalonic acid (MMA) in your urine. MMA is typically made in tiny amounts when you digest protein. Your body makes large amounts of MMA if you have a decrease in the amount of vitamin B12.
