Creamatocrit: Simple clinical technique for estimating fat concentration and energy value of human milk

Abstract

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 percentage 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. © 1978, British Medical Journal Publishing Group. All rights reserved.
