In my Clinical Review of macrocytosis errors appeared in the published version that I would like readers to be aware of (GP 16 November).
The maintenance dose of hydroxocobalamin for treatment of pernicious anaemia should be 1,000 microgram IM at three-month intervals for life (not 1,000mg as published).
The serum levels of vitamin B12 in the flow chart were wrongly printed in femtolitres (fl) when they should be pg/ml.
The photomicrograph of peripheral blood was not mine, bears no relation to pernicious anaemia and should not have been included in the article
