A device and method for sampling and testing the breath of human beings to detect maladies in the esophagus, stomach or gastrointestinal tract by the automatic analysis of the chemical contents of the sampled breath includes a container and a microprocessor-controlled valve for allowing a select portion of the breath to enter and be stored in the container upon exhaling through an inlet to the container so as to avoid storing air which is first exhaled. A normally open pressure switch or sensor activated by the pressure of the initial flow of the breath into an inlet tube from the mouth provides a start signal for controlling an electronic timer or microprocessor, which thereafter controls the sampling operation. The apparatus also includes passageways to several collection chambers, to permit multiple samples of the same or different body fluids to be collected and analyzed with a self-contained sensor or a remote analysis system.
