ABSTRACT:
Methods and apparatus are disclosed for determining the presence of a catabolic state in an organism (or collection of organisms) by measuring changes in isotopic ratios in biological materials obtained from them. Preferably, .sup.13 C/.sup.12 C ratios are monitored for isotopically unenriched animals, such as by testing changes in the ratio in blood or breath.
