Several reports have been published commending the use of 14C-labelled triglyceride breath tests in the assessment of fat malabsorption. We report further studies using gyceryl [14C]tripalmitate. Corrections for age, weight or metabolic rate failed to improve the test's ability to discriminate between malabsorbers and control subjects. A correction for respiratory quotient improved the linear correlation observed between the breath test results and daily faecal fat excretion. The significance of these findings is discussed and a number of problems identified which, at present, are preventing the introduction of breath tests for fat malabsorption into routine clinical practice.
已有多篇报告赞扬使用¹⁴C标记的甘油三酯呼气试验评估脂肪吸收不良。我们报告了使用甘油[¹⁴C]三棕榈酸酯的进一步研究。对年龄、体重或代谢率进行校正并不能提高该试验区分吸收不良者和对照受试者的能力。对呼吸商进行校正改善了呼气试验结果与每日粪便脂肪排泄之间的线性相关性。本文讨论了这些发现的意义，并指出了一些目前阻碍将脂肪吸收不良呼气试验引入常规临床实践的问题。
