A survey of haematological values in Sydney.

A survey of haematological values in Sydney was conducted in conjunction with the Sydney Coronary Heart Disease Prevention Programme. The sample consisted of 4374 'self-referred' Sydney inhabitants between 11-90 yr of age. Comparison of the haemoglobin concentrations with those obtained in 2 previous Australian surveys suggested that the haemoglobin values in Australia have not varied in the last 25 yr.
