title: Radioisotope determination of fat absorption.
abstract: A diagnostic method is presented for the quantitative  determination of fat absorption. The method utilizes breath analysis of radioactive 14CO2 and involves the measurement of both the fat and fatty acid absorption curves, whereby the fat absorption curve is directly compared to the fatty acid absorption curve for a particular patient. The test results are standardized by fitting all measurements to a gamma-density function.
