Accurate measurement of breath-borne analyte(s) is disclosed, in which such a measurement can be compared to a background level of the analyte(s) in an ambient air sample. Methods, systems, and devices can include use of this background level for the purposes of detection and/or measurement of an analyte (e.g., THC) in breath samples of for law enforcement, health, and safety applications.

Ambient contamination in breath analyte detection and measurement

Methods, systems and techniques for the accurate measurement breath-borne biomarkers are disclosed. Such methods, systems and techniques may be used for the purposes of detection and/or measurement in breath samples of biomarkers.

Biomarker detection from breath samples

An example breath collection and sampling device disclosed herein comprises a cartridge housing having a breath capture module, and a rotary valve operatively coupling a mouthpiece with the breath capture module. The rotary valve can have an open position where breath of a user can pass through the rotary valve, across capture sites of the breath capture module, and into a vacuum port, and a closed position for sealing the breath capture module from fluid passing through the rotary valve, while allowing the breath capture module to be exposed to a reagent for subsequent analysis of contents within the captured breath.

Rotary valve assemblies and methods of use for breath sample cartridge systems

Systems and techniques for detecting a target substance, such as THC, in a breath constituent sample are provided.

System and method for target substance identification

Methods, systems and techniques for the accurate measurement of breath-borne biomarkers are disclosed. Such methods, systems and techniques may be used for the purposes of detection and/or measurement in breath samples of biomarkers, e.g., biomarkers relating to a disease or a physiological condition.

Noninvasive point of care biomarker detection from breath samples

Systems and techniques for collecting and analyzing breath samples to detect one or more target analytes are disclosed.

Analyte detection from breath samples

Methods and devices for sampling, processing and identifying use of a substance or substances of abuse are provided. Systems and kits for sampling, processing and identifying acute use of a substance of abuse is also provided.

Device and method for detecting multiple target substances of abuse

Method and apparatus for detecting target substances using detection routines

Method and apparatus for detecting target substances using gradient determination

Method and apparatus for determining sample processes for detecting analysis substances

Systems, techniques and compositions can detect and measure a target substance, such as THC, in a constituent sample from exhaled human breath.

Detection and measurement of target substance in exhaled breath

Methods and devices for sampling, processing and identifying acute use of a substance or substances of abuse are provided. Systems and kits for sampling, processing and identifying acute use of a substance of abuse is also provided.
