Abstract

In 35 patients maintained solely on liquid formula diets, chromic oxide has been evaluated as an internal standard for balance studies that require stool collections. In 28 patients the excretion of chromic oxide was ideal: steady states were attained in which mean daily output was 90% (or more) of mean daily intake. In these patients corrections for fecal flow could validly be applied.
