A system for testing an individual for illicit or other substances is described. The system operates in tandem with a mobile device (smartphone) application, which employs a camera of the mobile device to capture and record the self-administered specimen collection process for verification and rule compliance. The system guides the user through the process via on-screen prompts on the mobile device, and includes tracking of the collected specimen from the moment of collection until it is sealed in a tamper-proof container to be mailed for external testing at a lab. A breathalyzer may also be used with the system to test for the presence of alcohol in the user's body, the use of which is also monitored and recorded via the on-board camera of the mobile device for verification.

Devices, systems, and methods for detecting molecules of interest within a collected sample are described herein. In certain embodiments, self-contained sample analysis systems are disclosed, which include a reusable reader component, a disposable cartridge component, and a disposable sample collection component. In some embodiments, the reader component communicates with a remote computing device for the digital transmission of test protocols and test results. In various disclosed embodiments, the systems, components, and methods are configured to identify the presence, absence, and/or quantity of particular nucleic acids, proteins, or other analytes of interest, for example, in order to test for the presence of one or more pathogens or contaminants in a sample.

Methods, systems, and apparatuses are disclosed for a tamper-resistant collection and retention a chemical sample. In one embodiment, the tamper-resistant system comprises a container operable to collect and retain a chemical sample, a tamper-resistant mechanism operable to disengage at a first chemical sample to allow for a collection of a chemical sample, wherein the tamper-resistant mechanism is operable to record one or more of: a date, a time, and a location, of the chemical sample during the collection of the chemical sample, and wherein the tamper-resistant mechanism is further operable to re-engage and lock after the collection of the chemical sample to resist subsequent chemical samples after the first chemical sampling.

A microfluidic device for the detection of drugs, explosives, chemical warfare, or other substances which is able to directly accept a swab into the device for testing. This device additionally contains on-board reagents to perform colorimetric testing for threshold determination directly in the device. These features are useful in a wide array of situations, such as at security checkpoints, environmental monitoring, clinical analysis, which require testing completely unknown substances and therefore must test for multiple different substances in one test. This is especially useful for police and other law enforcement officials who often must use field-deployable platforms making accurate field-testing critical for safety.

The method disclosed herein is utilized to educate and test students seeking field certification to be certified as a qualified observer for smoke opacity, including compliance with EPA method 9 certification. The method allows a user to train and test on their cell phone, electronic notebook, laptop, or other electronic device. The method allows immediate generation of test results, provides user feedback, incorporates whether the user is wearing glasses, incorporates the users orientation and distance to the smoke stack, and incorporates atmospheric conditions affecting opacity observation.

A kit for diagnosing a disease includes a micro device including a flow path through which a sample to be diagnosed flows, and one or more grooves at a bottom portion of the flow path, and an aperture having an opening corresponding with the flow path.

This system takes in raw cellular material collected using a provided swab, blood collection device, urine collection device, or other sample collection device and transforms that biological material into a digital result, identifying the presence, absence and/or quantity of nucleic acids, proteins, and/or other molecules of interest.

A device for collecting, shipping and analyzing a plurality of pathological specimens includes a plural number of collection vials for loading into testing vessel. Each vial can contain a reagent solution and a collector stick projecting from the inside of a stopper. The bottom of the vial can have a drain sealed by a frangible barrier. The vials can be inserted into chambers in the vessel that have a pintles oriented to break the barriers, allowing solution to flow onto one or more signaling elements such as a chromatographic strips. An insert drives the vials onto the pintles by simply screwing the vessel lid to its farthest position. The insert includes pins oriented to puncture sealed holes in the stoppers of each vial, facilitating the flow of solution from the vials. The analytical process can be performed in the absence of any contacting or manipulating of the vials and specimen collectors.
