The cost of electronic colposcopy is around 200 yuan for second-class hospitals; third-class hospitals are of a higher level and may cost more, and the charges of hospitals in different regions may also vary, with first-tier cities such as the north, Shanghai and Guangzhou having a high level of economy, and the cost will be relatively high. Currently, local hospitals have different brands of colposcopes and different instruments for examination, thus the cost will also be different. Some older colposcopes are simpler and cost less; some newer colposcopes are more advanced, with more items to check, and cost more. Colposcopy can simply check vaginitis and cervicitis; others need to do biopsy under colposcopy, and can also do acetic acid white test, the more items to be checked, the higher the cost will be.
