摘要：Breath test methods and apparatus for increasing accuracy and reducing thetime taken to achieve diagnostically useful results. In order to determine when an
increase in isotopic ratio of the exhaled breath is clinically significant, methods aredescribed for the use of a variable and multiple threshold level; for reducing the timetaken to determine an accurate baseline level; and for avoiding the effects of oral activitywhen making measurements. To increase measurement accuracy, methods are described,using the results of the breath tests themselves, of continuous and automatic self-calibration to correct for drifts in the gas spectrometer absorption curves. A method forincreasing the spectral stability of cold cathode discharge infra-red light sources for usein breath test instrumentation is described. Calibration checking devices and methods ofmandating their use at regular time intervals are described, to ensure maintenance of theaccuracy of breath tests.
