Thank you Mrs D-

I have a large HMO in the DC area and it's like pulling teeth to get anywhere with testing, etc. My primary cage Dr. did test for B12 1 1/2 years ago and the results were in the low 600's (while taking supplementation). She said at the last visit that "we already tested and it was good." From what I have read, there are several more tests that can be done to uncover a vit B12 deficiency. Will all the test outcomes be affected by 3-4 years of b12, folate, mulitb supplementation?

Thank you


ps-being new to this forum, I can't figure out how to find where my post went! Just found my posting and your response by chance. Have gone through the FAQ but my lack of knowledge about forum talk I guess was way below normal FAQ's! Have tried the "search" function but still working on tracking threads-
