Toxicant qualitative and semi-quantitative detection kit and toxicant qualitative and semi-quantitative method

Abstract

The invention provides a toxicant qualitative and semi-quantitative detection kit and a toxicant qualitative and semi-quantitative method. A 5ml detection liquid centrifugal tube, a 5ml blank centrifugal tube, a reaction colourimetric card and a qualitative detection strip are arranged in the kit; the 5ml detection liquid centrifugal tube contains 3ml detection liquid; and the reaction colourimetric card is that detection liquid is added when in different paraquat concentrations. The toxicant qualitative method comprises the steps of: (1), adding a sample to be detected into the detection liquid, wherein the mass ratio of the sample to be detected to the detection liquid is 1:4 to 4:1; (2), if the colour of the mixed solution in the step (1) is changed, representing that the sample to be detected contains paraquat; and (3), when immersing the immersing end of the qualitative detection strip in the sample to be detected, instantly changing the colour in a reaction tank, and representingthat the sample to be detected contains paraquat. According to the toxicant qualitative and semi-quantitative detection kit and the toxicant qualitative and semi-quantitative method in the invention,by utilization of the principle that sodium hydrosulfite and paraquat perform colour changing reaction in an alkaline condition, the qualitative detection strip and the qualitative and semi-quantitative detection kit are prepared; a novel diagnosis method can be provided for clinically excluding paraquat poisoning; and the kit effectively serves in clinic, and has very high social value.

Description

technical field [0001] The invention relates to the field of rapid medical detection reagents and test paper research and development, in particular to a poison qualitative and semi-quantitative detection kit and a poison qualitative method using the kit, which is applied to clinical rapid poison detection. Background technique [0002] At present, the detection of toxic substances in the country is limited to the detection of pesticide residues in public security and agronomy. In medicine, only a few hospitals can carry out toxic detection, and there are currently no rapid toxic detection kits for toxic substances in hospitals nationwide. The efficiency of clinical poisoning judgment Low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a qualitative and semi-quantitative detection kit for poisons and a qualitative and semi-quantitative method for poisons, and to prepare qualitative detection strips and semi-quan...
