Haemoglobin values in business executives.

Many series have been published on the values of haemoglobin in healthy men; these usually place the mean value at about 14 to 15 g./100 ml. in agreement with the commonly used figure of 14-6 g./100 ml. = 100 per cent. (Miale 1962; Pryce, 1960; Britton, 1963). Variations in different industries and occupations have not however been studied in depth (Williams, 1966: lead workers; Kilpatrick, 1961; Kilpatrick and Hardisty, 1961: coal miners and other workers). The data we present on 2,000 business executives is of interest in setting normal levels, because there is no other information on comparable higher income professional groups in Great Britain.
