1. A handheld breath sensing system comprising:
a main housing;
a first mouthpiece located on the main housing and configured to allow a user to exhale into the first mouthpiece;
a lid pivotably mounted to the main housing and movable between an open position in which the first mouthpiece is exposed, allowing the user to immediately exhale into upon opening of the lid, and a closed position in which the first mouthpiece is covered;
a sampling chamber located within the main housing and in fluid communication with the first mouthpiece;
a sensor in fluid communication with the sampling chamber and configured to measure at least one property of a user's breath in the sampling chamber; and
a microprocessor electronically coupled to the sensor and configured to process electronic signals from the sensor such that at least one volatile organic compound in the user's breath can be quantified and a resulting biomarker measurement provided to the user,
wherein the system further comprises a second mouthpiece configured to be interchangeable with the first mouthpiece and wherein an inside portion of the lid is configured to alternately hold the first mouthpiece or the second mouthpiece when the first mouthpiece or the second mouthpiece is not in fluid communication with the sampling chamber allowing the user to exhale through it into the sampling chamber, and
wherein the main housing and the lid in its closed position provide a closed volume of less than 8.0 cubic inches in which the first mouthpiece, the second mouthpiece, the sampling chamber, the sensor and the microprocessor are housed.
