A comparison of a Sahli haemoglobinometer and an AO/Spencer haemometer.
Both the Sahli haemoglobinometer and the AO/Spencer haemometer can give reasonably accurate and precise results under controlled conditions. Both have disadvantages for use in rural areas, but in the absence of any better alternative they will continue to be widely used. A quality control programme to check both instruments and operators is needed until a simpler, more dependable method becomes available.
