I've been advised that this is the best board to seek help interpreting some B12 lab results. I understand that this doesn't constitute medical advice, I would simply really appreciating hearing others' experiences.
My newest Active B12 lab results are 110pmol/L within the range of 25.1-165.0pmol/L.
My previous result from my GP was 575ng/L within the range of 200-700ng/L
I'm not sure how to interpret these two readings; there seems to be 2 different measurement systems. Can they be directly compared, and if so, is there a noticeable difference in the levels?
Thank you for you time
