Cervical liquid-based cytology is a diagnostic technique that detects cervical cells and classifies them cytologically using a liquid-based thin-layer cell detection system, which is a more advanced cytology technique for cervical cancer screening internationally. Married women should have cervical liquid-based cytology at least 1-2 times a year. The cervical liquid-based cytology reagent preservation solution can treat blood and mucus in the specimen, and the liquid-based cytology smear has a clear background and a clear cellular hierarchy, thus improving the quality of detection of cervical cell samples. Because conventional Pap smears are affected by blood, mucus, inflammation, etc., the background of the sample is often blurred and there are detection errors. In clinical trials, the number of liquid-based test cervical cell samples significantly improves the detection rate of cancerous cells and correspondingly reduces the number of Pap tests that need to be repeated, thus reducing unnecessary patient concerns caused by being retested. The reduction in routine Pap smear errors will inevitably raise the detection of pre-cancerous lesions to a new level and allow for early and more effective treatment of those patients with early cancerous lesions.
