1. A handheld, portable breath analyzer, comprising:
- a main body; and
a removable mouthpiece, wherein the removable mouthpiece removably attaches to the main body;
wherein the main body includes a sensor, a processor, a power source and an electrical circuit;
wherein the electrical circuit operably connects the power source to the sensor and connects the sensor to the processor;
wherein the sensor comprises a conductive material and hydrogen selective material in contact with the conductive material, wherein the hydrogen selective material has a resistivity that increases in response to increased concentration of hydrogen; and
wherein the processor detects resistivity of the sensor and uses the resistivity to calculate a concentration of hydrogen.

11. A breath test method for screening for a gastrointestinal disorder, comprising steps of:
-
(a) providing a portable, hand-held breath analyzer, wherein the portable, hand-held breath analyzer comprises; (i) a main body; and (ii) a removable mouthpiece, wherein the removable mouthpiece removably attaches the main body, wherein the main body includes a sensor, a processor, a power source and an electrical circuit, wherein the electrical circuit operably connects the power source to the sensor and connects the sensor to the processor;
wherein the sensor comprises a conductive material and hydrogen selective material in contact with the conductive material, wherein the hydrogen selective material has a resistivity that increases in response to increased concentration of hydrogen;(b) prompting a subject to exhale a breath sample into the removable mouthpiece; (c) allowing the processor to measure a resistivity of the sensor that occurs when the breath sample contacts the sensor; and (f) designating the subject as having an increased likelihood of having a gastrointestinal disorder if the measured resistivity is above and/or beneath a predetermined value. - View Dependent Claims (12, 13)
