Labs two months ago showed I was in the very low normal range, close to B12 deficient. I was also folate deficient. After two months of supplements and 4 weekly B12 injections, my labs now show I'm at the high end of normal range for B12 and folate. I had the labs one week after my last B12 shot and have continued taking it sublingually.
There's good reason to believe it could have been poor diet, but poor absorption is also in question as we continue to investigate chronic pouchitis versus a diagnosis change from UC to whatever crohns/colitis variant.
So I am keen to monitor my folate and B12 to see if I maintain it. My next B12 injection is in 3 weeks (going to monthly now). I am continuing folate and B12 by mouth and am better about getting veggies in the diet.
My question is when should I ask to have the labs done again? I'm thinking maybe right before the next B12 injection so there's 4 weeks since the last injection.
