- Screening should begin at age 21 years (previously at the age of first sexual intercourse)
- Frequency of screening: every two years for women aged 21-29 years; for women aged 30 and older -- if results have been negative for intraepithelial lesions and malignancy for three times they may be screened at every three years
- More frequent screening may be done in high-risk groups including: HIV infection, immunosuppression, exposure to diethylstilbestrol in utero, previously treated for CIN2, CIN3 or cancer
- Discontinue screening: at either 65 or 70 years in women with three or more negative cytology test results in a row and no abnormal results in the past 10 years; immediately after total hysterectomy for benign indications and no prior history of high-grade CIN
- Both liquid-based and conventional methods for cervical cytology are acceptable for screening
