Abstract:
Vitamin B(12) assays and inspection of peripheral blood films performed on 1,004 consecutive new patients over the age of 50 admitted to mental hospital led to the discovery of pernicious anaemia in only two cases. It is concluded that routine vitamin B(12) assays are justified only when fully-automated techniques have become available.
