Would someone be able to give me some feedback on the blood tests below. The notes from Blue Horizon did not comment on the ferritin but the remarks on B12 were borderline low and suggested 400 to 500 would be better. Are there any further tests I should take such as folate or to test for pernicious anaemia - what is the best way to raise my B12.
Ferritin 137.4 30 - 400 ug/L
Vitamin B12 244 142 - 725 pmol/L
