Embodiment Construction

[0034] Specific embodiments of the present invention will be described in detail below.

[0035] The preparation method of the ketamine urine detection kit quality control test plate comprises the following steps:

[0036] (1) Take negative urine and keep it for later use;

[0037] (2) Ketamine threshold detection urine preparation

[0038] (21) Weigh an appropriate amount of ketamine standard product in a 10ml volumetric flask, prepare a 1mg / ml stock solution with methanol, and then store the stock solution at minus 20°C;

[0039] (22) Take 100 μl of the stock solution obtained in step (21), add 9900 μl of negative urine from step (1) to it for dilution, and prepare an intermediate solution;

[0040] (23) Dilute the intermediate solution obtained in step (22) with negative urine into different concentrations of urine to be tested, and store all the urine to be tested at minus 20°C, wherein:

[0041] The urine to be tested with different concentrations includes the first ur...

Abstract

The invention, which belongs to the field of drug detection, particularly relates to a preparation method of a quality control test tray for a ketamine urine examination test kit. The preparation method comprises the following steps: (1), taking negative urine for standby application; (2), preparing ketamine threshold detection urine; (3), preparing anti-interference test urine; (4), freezing anddrying the prepared urine; and (5), packaging frozen and dried samples obtained in the step (4) into mutually spaced space of a quality control test tray respectively to obtain a quality control testtray for a ketamine urine examination test kit. The preparation method has the following beneficial effects: firstly, the method is simple; and secondly, the prepared quality control test tray is easyto store, transport or carry, so that the efficiency of evaluating the test liquid test kit is greatly improved.

Description

technical field [0001] The invention belongs to the field of drug detection, and in particular relates to a preparation method of a quality control test disk of a ketamine urine detection kit. Background technique [0002] Ketamine, a dissociative anesthetic, whose full name is 2-o-chlorophenyl-2-methylaminocyclohexanone, is a derivative of phencyclidine (PCP). Because its physical shape is usually white powder, and the first letter of its English name is K, it is commonly known as "K" powder. It is generally used as an anesthetic in clinical medicine. [0003] On June 9, 2001, the State Drug Administration of China included ketamine in the second category of psychotropic drugs for management. [0004] After taking ketamine, when encountering fast-paced music, it will twist strongly like a conditioned reflex, resulting in a state of separation of consciousness and sensation, leading to neurotoxic reactions and schizophrenia symptoms, manifested as hallucinations, motor dys...
