The purpose of scraping examination is to check whether there are precancerous cells in the cervix and whether there is a possibility of cancer, and the result will be available in 5 working days. It is recommended that women should choose 3-7 days after menstruation, because there is relatively less vaginal discharge during this period, so more cells can be scraped off. At present, clinical cervical smear has basically been replaced by TCT, which uses a small brush to take specimens deeper into the cervical canal, so that more cells can be shed and the area brushed will be deeper. It is recommended that women do TCT laboratory tests and also HPV laboratory tests for a comprehensive analysis of the two.
