B-12 Question for MrsD
MrsD: I just returned from my internist with a B-12 level at 379 pg/mL. I read your reply to Mark’s (Panorama) thread “IVIG Update” on 12-6-14 regarding his B-12 level of 429 as being too low with 400 (550 for Japan) being the new low. My results say that I need to be greater than 180. I can Google with the best of them and came up with ranges of 200-900; 170-250; 239-931. Can you please tell me your source for the “new acceptable low is now 400pg/ml. In Japan it is 550”? Based on your reply to Mark, I questioned my internist and he agreed to give me a B-12 shot and I bought B-12 supplements, however it’s not methylcobalamin as you suggest, but cyanocobalamin. Please tell me where you got your information?
Best regards.
Jim
