A simple micromethod has been devised for estimating the fat and energy content of human milk based on the centrifugation of milk in a haematocrit centrifuge. The % of cream, or 'creamatocrit', is read from the haematocrit capillary tube and is linearly related to the fat and energy content. The technique, which is rapid and cheap, may be used in clinical practice, in research and in epidemiological studies [accuracy is plus or minus 10 and plus or minus 6% for fat and energy resp.].
