A test strip for urinalysis is provided, the test strip including a reagent pad for detecting a concentration of a selected analyte, the reagent pad attached to the test strip and comprising a substrate and an analyte detection system retained thereon, the analyte detection system including a plurality of components necessary for detection of the selected analyte, wherein at least one of the plurality of components is a variable component, the variable component immobilized on the substrate at a plurality of amounts on the reagent pad.

A portable detection kit for identifying the presence of cannabinoids is provided and includes a colorimetric dye, a catalytic reagent, a solvent, a surfactant, and a delivery device containing a solvent or solvent mixture including the solvent. The delivery device is configured to deliver a portion of the solvent or solvent mixture to a target residue to form a sample residue. The colorimetric dye is configured to undergo a chemical reaction when the sample residue contains a cannabinoid. The chemical reaction is configured to produce a visible color change that corresponds to a predetermined cannabinoid of a plurality of cannabinoids.

The present invention provides an apparatus for detecting the presence or absence of an analyte in liquid sample, including: a collection chamber, including an opening for collecting a liquid sample; a testing element for testing the analyte in liquid sample; and a cover for covering the opening of the collection chamber; wherein the apparatus further includes a prompting device for prompting if the cover is covered to a specified location, and the prompting device shall at least includes a first element and a second element, the first element is in contact with the second element, wherein one element vibrates to produce a sound. In some preferred ways, the second element produces friction with the first element, to cause one of the elements to generate vibrations. The apparatus in the present invention can allow the prompting sound to be clear and loud.

Embodiments of the disclosure provide a method of managing information related to a cannabis product across a distributed validated system. The method includes enabling an authorized user to create a plurality of data containing genetic profile of a seed, plant growth conditions of a crop, and manufacturing information used for production of the cannabis product, and measurements of quality and quantity of desired components and undesired components in the cannabis product. The method includes associating the plurality of data to a record which is identified by a unique identifier. The method includes storing the record into a memory for access by one or more of a plurality of authorized users using the unique identifier. The method includes analyzing the cannabis product to determine the quality and quantity of desired components and undesired components in the cannabis product. The method includes determining concentration of cannabinoids in the cannabis product.

Systems, devices, and methods for detecting cannabinoids in liquid or gaseous samples. In one aspect, the present invention uses a sensor element and two electrical circuit elements. When the sensor element is in contact with a sample containing cannabinoid, interactions between the sensor element and the cannabinoid changes or affects the sensor element's electrochemical properties. Using the two electrical circuit elements, this change can be detected. An analog signal relating to the changed electrochemical properties can be measured using the two electrical circuit elements. In one implementation, there is provided an organic field effect transistor (OFET) whose signal changes when in contact with a cannabinoid containing sample.

A method and system in accordance with the subject invention establishes industry norms for every step in the production, cultivation, harvest, and packaging process for a regulated industry to follow with respect to a regulated product. An embodiment relates to the regulated product cannabis where product is accurately recorded into the system is legal while any product that is not recorded into the system is illegal.

The invention provides a method and a structure for balancing cannabinoid metabolites within a patient. Using a stool sample, a panel of cannabinoid metabolite levels is established and compared to ideal ranges thereof. Metabolites outside of the ideal range are treated with a cannabis product or alternatively with traditional medicines.
