The technologies described enable tracking statuses of and performance metrics for alcohol sensing devices, with respect to performing device integrity checks in order to ensure that testing of provided samples is performed properly. Systems described include alcohol testing devices including flow tubes, alcohol sensors, pumps, supplementary sensors, processors, and user interfaces. Methods described include steps for performing a set of integrity checks in coordination with receiving samples (e.g., breath samples, transdermal samples, etc.) from users.

Method and system for detecting and maintaining performance of an alcohol sensing device

A method for monitoring intoxication of a user, the method including: receiving a set of samples from a body region of a user; generating an intoxication metric based on the set of samples; and providing a notification to the user based on the intoxication metric. The method can additionally or alternatively include: modifying operation of the transdermal alcohol sensing device based on the intoxication metric; determining contextual data; maintaining a hydration level of the transdermal alcohol sensing device; and any other suitable processes. A system for monitoring intoxication of a user including a sensor and a housing. The system can additionally or alternatively include any or all of: an inlet, a fastener, an electronics subsystem, a user device, and/or any other suitable component.
