====Liquid-based thin prep====
A more recent study of the convention method reported very similar results:<ref name="pmid17942871">{{cite web |url=http://content.nejm.org/cgi/content/full/357/16/1579 |title=Human Papillomavirus DNA versus Papanicolaou Screening Tests for Cervical Cancer |accessdate=2007-10-18 |format= |work=}}</ref>
Liquid-based thin prep is more [[sensitivity (tests)|sensitive]] than the conventional Papanicolaou smear.

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]

Ability to detect ASCUS or worse.[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]

Human papillomavirus testing

Combined testing

If either the Papanicolaou smear or Human papillomavirus testing are abnormal:
