Problems solved by technology

[0005] However, in the actual testing process, when testing the urine samples of suspected drug addicts, if the drug addicts evade the inspection by diluting their own urine samples or changing the package, the accuracy of the test results will be affected.
Although the existing methamphetamine rapid detection card (colloidal gold method) can achieve rapid detection, it cannot effectively avoid the missed detection caused by the dilution of urine samples by suspected drug users and the falsification of packages.

Abstract

The invention relates to the technical field of biological detection, in particular to a methylamphetamine detection card for preventing urine samples from being counterfeited as well as a preparation method and application of the methylamphetamine detection card. The methylamphetamine detection card comprises a temperature sensing area, a methylamphetamine detection area and a urine property detection area, wherein the temperature sensing area is used for detecting the temperature of urine, the methylamphetamine detection area is used for detecting the content of methylamphetamine, and the urine property detection area is used for detecting the physicochemical properties of the urine; the detection card can be used for simultaneously detecting the content of methylamphetamine in a urine sample and detecting whether the urine sample is diluted or not, and has higher specificity and sensitivity on the detection of the counterfeiting of the urine sample and the detection of the content of methylamphetamine; the detection card can effectively prevent leak detection caused by the counterfeiting of the urine sample due to dilution and the like, improves the accuracy of methylamphetamine detection, and has important application value in methylamphetamine detection.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a methamphetamine detection card for preventing urine sample fraud and its preparation method and application. Background technique [0002] Methamphetamine (methamphetamine, methamphetamine, methamphetamine) is a new type of drug, and it is the most widely abused drug in the world in the 21st century. Due to the strong toxicity of methamphetamine, long-term inhalation will reduce human immunity, cause damage to body organs, and cause death in severe cases. In addition, smoking methamphetamine can cause strong stimulation to the central nervous system of the human body, and large doses can lead to mental disorders in the human body, manifested as emotional impulsiveness, paranoia, and delusions, which can easily lead to violent behavior. [0003] The detection methods of methamphetamine mainly include chromatography, enzyme-linked immunosorbent assay (ELISA) method,...
