Abstract: The present disclosure relates to devices and methods for determining a target analyte in a sample (e.g., a bodily fluid sample such as sweat, blood, urine, lavage, plasma, saliva, tears) using an analysis device (e.g., a bodily fluid analysis device). The device may include a lateral flow assay in some embodiments. Certain embodiments involve determining a concentration of a target analyte in a sample by generating a volumetric calculation of the sample and/or by use of a non-target analyte. The devices and methods can be used for obtaining and processing a sample to determine the presence and/or concentration of such analytes. In some cases, the methods and/or devices can be used to determine impairment (e.g., drug impairment) in a subject.

Abstract: The invention provides methods and products, such as kits, useful for determining the apoptotic state of cells in an organism, comprising detecting the presence or abundance of at least one caspase affinity labeling agent in the cells of an animal into which at least one caspase affinity labeling agent has been introduced, wherein the presence or abundance of the caspase affinity labeling agent correlates with the apoptotic state of the cells.
