I have a history of high serum B12 & folate levels, like past the limit of the Labcorp ranges (my last B12 test came back as >1999). Yet at the same time my MMA came back as within range but elevated.
Obviously low B12 & folate tests are a more common problem, but way high makes me think there is something off and potentially worth further investigation.
Issue is I'm not quite sure quite how to break down the problem. I could get something like Doctors Data's folate metabolism test done to determine whether my folate values were being inflated by large amounts of unmetabolized folic acid.
When it comes to the B12... Generally speaking MMA is used to confirm an issue, but considering the results are somewhat contraindicating I'm not sure quite where to go with the next step.
My current preliminary hypothesis is, that in a broader sense, something is minimizing my utilization of B12 & Folate and thereby causing elevated levels. The question is is there an issue with the B12 causing a folate issue, vice versus or something that is preventing the utilization of both.
Any suggestions on where to start breaking down the problem?
