For the second time in 3 years my B6 level is more than double the the ref range. My B2 is low. My B3 is low. My B1 is low. My B12 is on the low side. And my D is low..My WBC count is low as well. I have seen an Oncologist for this issue and have been told she has no idea what the problem is. PLEASE tell me what type of physician I should be seeing for this (these) issues. Thank you!
