Processing method for detecting clinical cell specimen

Abstract

The invention relates to a method for treating clinical testing cell samples, which comprises coating a filter on a test tube or a centrifuge tube or a sediment tube, decanting preservative fluid which contains clinical cytological specimen cells into the test tube or the centrifuge tube or the sediment tube. Needless materials as needless large necrotic organizations, non-dissolved mucus, sludged blood, other large impurities, and the like are left inside the filter, and cells inside the filter liquid is made into a clear thin-layer cell smear. Beneficial effects of the invention are that the needless materials as the needless large necrotic organizations, the non-dissolved mucus, the sludged blood, the other large impurities, and the like can be separated out through the filter, and thereby disease conditions can be judged more precisely through made cell smear.

Description

technical field [0001] The invention relates to a processing method for clinical detection of cell samples. Background technique [0002] Cytodiagnostics, also known as cytopathology or clinical cytology, is to make cells into cell smears, develop color by cytochemistry or immunocytochemistry, based on cytology, guided by histopathology, in cell smears Observe various normal and pathological cells, comprehensively analyze their lesion properties, and achieve the purpose of diagnosing diseases or lesions. Cytological diagnostics can be used for the examination of various exfoliated cells in the female reproductive tract, esophagus, respiratory tract, ascites, urine, etc., and can also be used for cells obtained by fine needle aspiration of the breast, liver, etc. Simple, cost-effective pathological diagnosis method. [0003] The cytological smear technique is to directly smear the mucus containing exfoliated cells attached to the cervical cell collector on the glass slide, ...

AI Technical Summary

Problems solved by technology

[0004] However, the Pap smear has a high rate of misdiagnosis for several reasons

[0005] (1) Only 10% to 30% of the cells on the collection device can be transferred to the glass slide, and the rest of the cells are discarded, so the diseased cells may be missed and cannot fully reflect the disease;

[0006] (2) The smear cannot be dried and should be fixed with a fixative solution within 15 to 30 seconds, but it is difficult to do it in actual work, which is easy to produce the artificial illusion of cell deformation;

[0007] (3) Excessive mucus, red blood cells, white blood cells, etc. on the smear will cause difficulties in reading the film, easily cause reading fatigue, and make it difficult to find diseased cells;

[0008] (4) The exfoliated cells accumulate and overlap, so that the abnormal cells are covered, which will seriously affect the observation of the cells, and it is difficult to make an accurate judgment

[0010] However, liquid-based cytology technology often cannot completely decompose a large amount of mucus and necrotic and detached large tissues in cell specimens, so that these non-diagnostic substances seriously reduce the quality of slides
