Points to note after the Cervical Smear (Pap Smear) Test

Points to note after Cervical Smear (Pap Smear) Test


It is common and normal to have slight vaginal bleeding in the first two days after the cervical smear test. If bleeding persists or becomes more severe, please phone the Maternal and Child Health Centre (MCHC) for follow-up or seek medical advice from your family doctor.

Understanding the Cervical Smear result

  • A “negative” or “normal” result means that there are no abnormal cell changes detected in your cervical smear specimen, or detection of benign conditions which have no significant bearing on long-term health and do not require follow-up.*
  • A “positive” or “abnormal” result usually means that there are some changes in the cells of your cervix which may need further follow-up or investigation. It does not necessarily mean that you already have cancer.

Cervical screening is not 100% accurate

As with any other screening tests, the cervical screening test is not 100% accurate. Different researches have shown that there may be 5 to 20% inaccuracy.

The test may sometimes miss a real abnormality (false negative) or wrongly classify normal cells as abnormal (false positive). Possible causes are:

  1. The quality of the cell sample is affected due to:

    Before the test:

    • sexual intercourse;
    • use of pessaries or spermicides;
    • douching (shower and bath would not affect the quality);

    During the test:

    • vaginal discharge caused by a vaginal infection;
    • Menstrual blood.
  2. Sample handling errors.
  3. Abnormal cervical cells are situated at a site which is difficult to reach inside the cervical canal.
  • Although cervical screening does not have 100% accuracy, this is not a cause for worry, because cervical cancer normally takes 5 to 10 years to develop.
  • REGULAR cervical screening can prevent the development of 90% or more of the cervical cancers.
  • Even if the previous smear is normal, women should still continue with regular cervical screening.
