Embodiment 1

[0022] Example 1, sodium azide 0.1%, potassium chloride 0.9%, ethanol 4.5%, ethylene glycol 2.8%, benzalkonium chloride 0.3-1.2%, sodium dodecylsulfonate 4%, glacial acetic acid 5%, The balance is purified water, and the above-mentioned components can be evenly stirred and dissolved.

[0023] The cleaning solution prepared by the above embodiment reduces the cost of use during use, effectively decomposes and removes impurities such as red blood cells and mucus clumps in the sample, and extracts effective cells to be tested, so that liquid-based cytology experiments When the slides were read, the background was clear, and the exfoliated cells with diagnostic significance were completely and easily identifiable, evenly spread on the preparation area of ​​the glass slide with almost no accumulation.

Abstract

The invention provides a sample extracting liquid for liquid-based cytology experiments, which comprises sodium azide, potassium chloride, ethanol, ethylene glycol, benzalkonium chloride, sodium dodecyl sulfate, glacial acetic acid, and purified water. According to the extracting liquid, the cost of use is reduced, and impurities such as erythrocyte and mucus masses in a sample can be effectivelydecomposed and removed to obtain effective cells to be tested, and therefore, slide reading backgrounds in liquid-based cytology experiments are clear, and cast-off cells having diagnostic significance are complete in shape, easy to distinguish and uniform, and are paved on a section making region of a glass slide almost without stacking.

Description

technical field [0001] The invention relates to the technical field of biological preparations; in particular, it relates to a sample extract for liquid-based cytology experiments. Background technique [0002] Liquid-based thin-layer cell film production technology is an integral part of pathological diagnosis, and the quality of film production technology directly affects whether pathologists can make correct pathological diagnosis. [0003] The third-generation cytology production technology—liquid-based sedimentation production, entered the Chinese market at the end of 2001. Compared with the traditional Pap smear examination, it significantly improved the satisfaction of specimens and the detection rate of abnormal cells, and solved the problem. Traditional smears have high false negative rate, high rate of lost cells, poor smear quality, excessive mucus, blood or inflammatory cells and other technical problems, which have made a significant contribution to the diagnosi...
