A breath test analyzer, which analyzes exhaled breaths of a patient for isotope labeled products generated in the patient's body after ingestion by the patient of an isotope labeled substance, where the presence of these isotope labeled products provide an indication of a medical condition in the patient. The analyzer uses a very sensitive infra-red spectrophotometer, which enables it to continuously collect and analyze multiple samples of the patient's breath, and process the outputs in real time, while the patient is still connected to the analyzer, such that a definitive result is obtained within a short time, such as the order of a few minutes. The breath test analyzer is sufficiently small that it can be easily accomodated in the office of a physician. The breath test analyzer can be utilized for a number of diagnostic breath tests, according to the isotope labeled substance ingested by the patient and the gases detected in the patient's breath.
A method of breath testing in which samples collected from exhaled breaths of a subject are analyzed by means of an analyzer, for a product of an isotopically labeled substance ingested by said subject, and comprising the steps of:
A method of breath testing comprising the steps of:
A breath test analyzer which substantially continually collects samples of a subject's exhaled breath for analysis for a product of an isotope labeled substance ingested by said subject, and determines that said test has a clinically significant outcome in accordance with the results of the ongoing analyses of said samples.
A breath test analyzer which analyses a first sample collected from at least a first exhaled breath of a subject and a second sample collected from at least a second exhaled breath of said subject for a product of an isotope labeled substance ingested by said subject, while the subject is coupled to the breath test analyzer.
