Problems solved by technology

In the TCT examination, doctors usually use a special cervical cell sampling brush to collect cells. During the collection process, the collected mucus and leucorrhea often affect the diagnostic doctor's interpretation of impurities due to the different lesions of individual patients. Physician reading and diagnosis caused great interference

Abstract

The invention provides cell extraction solution and an application thereof, and belongs to the technical field of agents. The cell extraction solution comprises, by weight, 29-35 parts of glycerol, 0.005-0.015 part of potassium chloride, 0.01-0.03 part of monopotassium phosphate, 0.1-0.2 part of sodium hydrogen phosphate, 0.5-1 part of sodium chloride, 0.4-0.8 part of ethylene diamine tetraaceticacid, 0.05-0.15 part of phenoxyethanol and 63-69 parts of water. By the aid of the cell extraction solution, mucus and leucorrhea in a sample can be removed, squamous cells can be extracted, so that impurities and the squamous cells are separated, a doctor conveniently reads pieces and diagnoses, and the efficiency and the accuracy rate of a doctor in liquid-based cytological diagnosis.

Description

technical field [0001] The invention relates to the technical field of medicaments, in particular to a cell extract and its application. Background technique [0002] Cervical cancer, also known as cervical cancer, is a malignant tumor that occurs in the lining epithelium and glandular epithelium of the cervix. Cervical cancer is a common gynecological malignancy, and its incidence rate ranks second among female malignancies in recent years. [0003] At present, the commonly used cervical cancer screening is liquid-based cytology test (TCT test), which uses a liquid-based thin-layer cytology detection system to detect cervical cancer cells and perform cytological classification and diagnosis. In the TCT examination, doctors usually use a special cervical cell sampling brush to collect cells. During the collection process, the collected mucus and leucorrhea will affect the diagnosis doctor's interpretation of impurities due to the different lesions of individual patients. P...
