hi I have just received my latest blood results today all seems ok. and it says no further action, but I,m a little confused with some of the results,
serum ferritin- Normal-No 32 ug/l 11.00-307.00 ugl
serum vit b12-(SJ17021 ) - No 166 ng/l 145.00-910.00 ng/l Action
does this mean I am deficient in B12 as I have been so tired for weeks or am I interpreting these figures wrong I would be greatful for your advise thanks
