Women who have regular gynecological checkups know that there is a test called TCT test, which uses a liquid-based thin-layer cell detection system to detect cervical cells and perform cytological classification and diagnosis. What is the importance of TCT? What is TCT test? TCT test is called “liquid-based thin-layer cytology test”, which is a leading international cervical cancer prevention cytology examination technology. Adopting the core technology of high precision filtration membrane and microcomputer automation control system, the cell film made by this method has the incomparable advantages of traditional smear. It is one of the most advanced cervical cancer cytology examination techniques in the world, which significantly improves the satisfaction of specimens and the detection rate of abnormal cervical cells compared with the traditional Pap smear examination. TCT is simply a cancer screening test. It is the most advanced cervical cancer cytology examination technology in the world, which adopts the core technology of high precision filtration membrane and microcomputer automation control system, and the cell film made by its method has the advantages that traditional smear cannot compare. Its principle is to use advanced liquid-based cell preservation technology and computer-controlled filtration technology to make smears from cells collected on the sampler to diagnose mycobacterial infections, bacterial infections, human papilloma virus infections and herpes virus infections, etc. It is the most advanced technology for cervical cancer screening in women. II. Introduction to cervical smear (TCT) A cervical smear is a small sample of cells taken from the cervix, placed on a glass slide and then studied under a microscope for abnormalities. Thanks to the introduction of this test, the mortality rate of cervical cancer has been reduced by at least 70%. With a simple pap smear, doctors can detect tiny, very early changes in the cells of the cervix, which allows deadly cancers to be sniped even before they actually occur. Pap smear is currently the easiest and most effective diagnostic method for widespread detection of cervical cancer. Cervical smear is very simple and the whole procedure takes only 3 to 6 minutes. This diagnostic method does not cause cervical injury and does not cause pain. Third, what is the importance of doing TCT examination TCT gynecological examination can detect mycobacterial, trichomonas and herpes virus infections which are multi-infectious diseases. The next step for doctors to do is usually to treat the microbial infections accordingly to relieve the symptoms. Currently, cervical cancer is still an important killer of women’s health. Its incidence rate is the second highest among female malignant tumors, after breast cancer. According to 2000 statistics, there are about 500,000 new cases of cervical cancer worldwide each year, and there are about 130,000 new cases in China, accounting for about a quarter of the new cases in the world. About 20,000-30,000 people die from cervical cancer every year, and the trend is increasing and getting younger. Once women have symptoms such as abnormal leucorrhea, lumbosacral pain or lower abdominal cramps, it may mean that your cervical health is on the “red light”. TCT is the most advanced cervical cancer detection technology in the world. Women who are 18 years old or older and have had sexual intercourse should undergo TCT every 1-2 years, even if you have stopped having sex or are no longer menstruating.
