Human papillomavirus DNA detection


What is this test?

This test detects DNA gene sequences of a type of virus called human papilloma virus (HPV) in cervical cells. It is used to detect potentially cancerous forms of this virus.

Why do I need this test?

Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:

  • Atypical squamous cells
  • Screening for malignant neoplasm of cervix

How should I get ready for the test?

Written consent will be required for endocervical sampling. Review the consent form with the healthcare worker and ask any questions that you have before signing the consent form.

Tell the healthcare worker if you have a medical condition or are using a medication or supplement that causes excessive bleeding. If possible, schedule the procedure one week after your menstrual period. Do not douche or have sexual intercourse for 24 hours before the procedure.

You may be asked to urinate prior to your endocervical sampling. This will make it easier for the healthcare worker to see your cervical canal during the procedure and may make the procedure more comfortable for you.

How is the test done?

For an endocervical sampling, you will be asked to lie on your back with your legs spread and feet placed in stirrups. A speculum will be inserted into your vagina. This tool is used to gently spread apart your vagina. A small brush is inserted into the endocervical canal and rotated. This is done to collect cells. Once a sufficient sample is collected, the brush is removed. The sample off the brush is then sent for testing.

How will the test feel?

The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the procedure. Inform the person doing the procedure if you feel that you cannot continue with the procedure.

You may feel mild discomfort, cramping, or pain during an endocervical sampling.

What should I do after the test?

After endocervical sampling, you may experience some light spotting (mild, occasional bleeding from the vagina). Generally, there are no activity restrictions after this procedure.


You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
