Evaluation of malabsorption test using14c triglyceride

A FURTHER evaluation of the14C fat absorption test is reported.14C blood levels have been measured during the test and give good separation between normal controls and the patients with malabsorption. However, patient to patient variation within each group was greater than when the14CO2 was measured in the breath. The lower14CO2excretion and14C blood levels found in obese subjects have been further investigated and the results are discussed. It is concluded that this test may replace the routine estimation of faecal fat on a three-day collection in the investigation of a patient with suspected malabsorption. We wish to thank Dr. D. A. D. Montgomery for his helpful criticism. We would also like to thank Mr. S. J. Todd for technical assistance in the14C estimations.
