Screening
In a randomized controlled trial, the addition of Human papillomavirus testing to screenng for cervical cancer "reduces the incidence of grade 2 or 3 cervical intraepithelial neoplasia or cancer detected by subsequent screening examinations."[1]
Papanicolaou smear
A systematic review of available studies found the follow results.[2]
| ASCUS or worse | High grade or worse | |||
|---|---|---|---|---|
| sensitivity | specificity | sensitivity | specificity | |
| Conventional method | 88% | 71% | 55% | 97% |
| Liquid-based thin prep | 88% | 71% | 57% | 97% |
A more recent study of the convention method reported very similar results:[1]
- sensitivity 55%
- specificity 94%
Human papillomavirus testing
- sensitivity 95%[1]
- specificity 97%[1]
Combined testing
If either the Papanicolaou smear or Human papillomavirus testing are abnormal:
- sensitivity 100%[1]
- specificity 93%[1]
