I was hoping someone here might have experienced something similar to me. I am a 24 year old female. I asked my doctor to test my B vitamin levels and homocysteine because I thought I might have a B12 deficiency (due to symptoms like zero energy). my levels came back as serum B12 1314pg (ref 200-1100pg) serum folates 20.4ng (ref >5.4ng) homocysteine 7.4umol (ref <10.4umol) I don’t supplement with B vitamins, so why are my levels so high? And having such high levels, why isn’t my homocysteine lower? I couldn’t get the doc to run a methylmalonic acid test, and I am going to get tested for genetic mutations via 23andme ASAP. do these numbers look suspicious to you, or am I being a hypochondriac? I am wondering if I should try to get tested for holotranscobalamin to see if my body is actually using the B Vitamins it purports to have.
