PAP Smear

An in office medical screening procedure used to collect cells from the cervix for examination under a microscope. Pap smears are performed to detect abnormal changes in cervical cells that may indicate cervical cancer or precancerous conditions. This preventive measure aims to identify abnormalities early, allowing for prompt intervention and treatment.

Key Features:

  • Indications:
    • Pap smears are recommended as part of routine cervical cancer screening for individuals with a cervix, typically starting at age 21 and continuing at regular intervals as determined by guidelines and individual risk factors.
    • They are also used for follow-up testing in individuals with abnormal cervical cancer screening results or other risk factors.
  • Purpose:
    • The primary goal of a Pap smear is to detect abnormal changes in cervical cells, such as dysplasia or neoplasia, which may indicate the presence of cervical cancer or precancerous lesions.
    • Early detection and treatment of these abnormalities can prevent the progression to invasive cervical cancer.
  • Accuracy:
    • Pap smears have a high sensitivity for detecting cervical abnormalities but may have limitations, including false-positive and false-negative results.
    • To improve accuracy, Pap smears are often combined with human papillomavirus (HPV) testing, which can identify high-risk HPV types associated with cervical cancer.
  • Frequency:
    • The frequency of Pap smears varies depending on factors such as age, prior screening history, and individual risk factors.
    • Most guidelines recommend screening every three to five years for individuals with normal results and no significant risk factors.
  • Follow-up:
    • Individuals with abnormal Pap smear results may require further evaluation, including colposcopy (examination of the cervix with a magnifying instrument) and biopsy, to determine the extent of the abnormalities and guide management.
