Vaginal secretion dry chemical analysis liquid quality control material and preparation method thereof

Abstract

The invention discloses a vaginal secretion dry chemical analysis liquid quality control material and a preparation method thereof. A corresponding buffer system is prepared first, and then, with the buffer system as a solvent, a plurality of raw materials of a negative quality control material and a positive quality control material are added and dissolved; when different components are added, the next component can be added after the previous component is completely dissolved; in order to ensure the enzyme activity, a liquid negative quality control material and a liquid positive quality control material are prepared in an environment of 4-15 DEG C, and the effect is better; after the preparation is completed, subpackaging and storage are carried out within 24 hours, and quality control can be carried out on 10 items such as coagulase, hydrogen peroxide, lactic acid, oxidase, glucuronidase, N-acetyl hexosaminidase, sialidase, leukocyte esterase, proline aminopeptidase and pH value at the same time, so that the stability is good, the period is long, the use is convenient and fast, complex step of redissolving before the freeze-dried product is used is omitted, and errors caused by redissolving are reduced; and the liquid quality control material has a good practical application value.

Description

technical field [0001] The invention relates to the technical field of clinical testing of vaginal secretions, in particular to a liquid quality control substance for dry chemical analysis of vaginal secretions and a preparation method thereof. Background technique [0002] The current quality control substances for dry chemical analysis of vaginal secretions are mainly freeze-dried products or single-item liquid quality control solutions. During the use of freeze-dried products, they need to be redissolved, mixed, and warmed up again. Many factors affect the quality control substances. , the operation is cumbersome; and the single-item liquid quality control solution has problems such as easy confusion due to the large number of items and cumbersome operation in the multi-item quality control, resulting in a decrease in practical value. Contents of the invention [0003] The object of the present invention is to provide a liquid quality control substance for dry chemical ...
