The difference between cervical scraping and cervical TCT

Cervical scraping and cervical TCT are two different cervical cancer screening methods. The main difference lies in detection technology and accuracy.

1. Detection technology

Cervical scraping is a traditional cytological examination method by scraping cells from the surface of the cervix for Pap staining and then observing them under a microscope. Cervical TCT uses liquid-based thin-layer cytology technology. The cells are dispersed in a special preservation solution to form a thin-layer sample, which can reduce the interference of blood and mucus and improve the cell detection rate.

2. Differences in accuracy

The cell detection rate of cervical TCT is significantly higher than that of traditional scraping, and more abnormal cervical lesions can be found. The detection rate of cervical precancerous lesions by cervical TCT can reach more than 90%, while the detection rate of traditional scraping is about 60%. TCT technology can effectively reduce false negative results.

3. Inspection process

During cervical scraping examination, the doctor needs to use a scraper to directly scrape off cervical exfoliated cells, which may cause slight discomfort and bleeding. Cervical TCT uses a special brush to collect cells inside and outside the cervical canal. The sampling is more complete, the operation is relatively gentle, and the subject feels less discomfort.

4. Price difference

The cost of cervical TCT examination is usually 2-3 times higher than that of traditional scraping. This is because TCT requires special specimen preservation solution, precision production equipment and professional detection technology. However, considering the high accuracy of TCT, its cost performance is relatively higher.

5. Applicable groups

Women over the age of 25 who have a history of sexual intercourse are suitable for both examinations. Cervical TCT is especially recommended for people with high-risk factors for cervical lesions, such as a history of HPV infection, previous abnormal cytology, or those with low immune function.

No matter which examination method you choose, it is recommended that women of appropriate age undergo regular cervical cancer screening. Women under the age of 30 can undergo cervical cytology examination every three years, and it is recommended that women over the age of 30 undergo combined HPV testing. Maintaining good living habits, paying attention to perineal hygiene, and getting the HPV vaccine can help prevent cervical lesions. If abnormal results are found during screening, you should promptly go to a gynecologist for further examination.
