Cell processing kit and using method therefor

Abstract

The invention provides a cell processing reagent box for cell detection and its usage method, the reagent box including the specimens preserved fluid, the separating and cleaning fluid, the packet diluted base liquid, and also the cell reserved liquid. Using the reagent box to process the cells, the operation is simple and fast, no need special equipments, low-cost, and good cells processing effect, which will help enhance the accuracy rate of detection, and can be widely applied to the clinic and laboratory.

Description

technical field [0001] The invention relates to a cell processing kit and its use method, in particular to a cell sample processing kit for clinical testing and its use method. technical background [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 uterus is an important organ unique to women. It is divided into two parts: th...

AI Technical Summary

Problems solved by technology

[0011] ②Low sensitivity: Due to the limited sensitivity of traditional Pap smear testing, the effective rate of detecting cervical cancer is only 51%

[0012] ③High false positives and poor repeatability: poor repeatability of the test results in instability, prone to false positives, which will not only burden the patient with unnecessary costs for further examination, but also cause mental harm to the patient

[0014] The main reason is errors caused by specimen handling flaws inherent in the method itself

[0015] (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;

[0016] (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;

[0017] (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;

[0018] (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

[0032] However, at present, these technologies are all completed by machines, which have the disadvantages of complicated machine operation and high price, which will undoubtedly increase the medical cost and patient burden.
