Problems solved by technology

[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. The freeze-dried products need to be re-dissolved, mixed, and warmed up during use, and the quality control materials are affected by many factors. , 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

Embodiment Construction

[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0017] In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0018] The invention provides a liquid quality control substance for dry chemical analysis of vaginal secretions. The liquid quality control substance for dry chemical analysis of vaginal secretions includes a negative quality control substance and a positive quality control substance. The negative quality control substance includes a pH value of 3.5- 5.0 buffer system 50~500mmol / L, preservative 0.01~0.5g / L,...

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 ...
