Sounds like I should also request homocysteine testing. Thanks again!

If you are not using methylB12 already, and had that test routinely for B12, and it measured other B12 in the serum not being converted... you could still be low in ACTIVE B12.
An MMA and/or homocysteine test will be high when B12 is not being utilized by the body correctly... and is more definitive for those who have the MTHFR mutation. There are several types of MTHFR also ,, which is beyond me, I am sorry to say.
