Abstract
THE advances which have been made in the measurement of hæmoglobin concentration have been largely offset from the clinical point of view by the continued inaccuracy of the red cell count. Hæmoglobin concentration can be estimated by quite simple apparatus with results that have a coefficient of variation of less than 3 percent1, whereas the corresponding figure for red-cell counting is about 9 per cent2.
