HPV DNA Test: What Canadians Need to Know (2025)

An HPV DNA test is one of the most effective tools for detecting the human papillomavirus — the most common sexually transmitted infection worldwide. This test identifies the exact strain of HPV you carry and determines whether it raises your risk of cervical cancer or other genital cancers.

How the HPV DNA Test Works in Canada

For Canadians, HPV screening for cervical cancer is becoming a cornerstone of routine sexual health care. Several provinces are now shifting from traditional Pap smears to HPV genotyping as the primary screening method. Understanding how this test works, who should get it, and what the results mean can empower you to make informed decisions about your health.

HPV DNA Test and Related HPV Types: Characteristics and Management in Canada

HPV Type Category	Associated Health Risks	Detection via HPV DNA Test	Recommended Management
High-Risk Types 16 & 18	Responsible for approximately 70% of cervical cancers; also linked to oropharyngeal, anal, and genital cancers	Specifically identified by genotyping; flagged as high priority on HPV DNA test results	Immediate colposcopy referral recommended regardless of cytology result; close follow-up with gynecologist
Other High-Risk Types (31, 33, 45, 52, 58)	Associated with cervical, vulvar, vaginal, and anal cancers; lower individual risk than types 16/18 but collectively significant	Detected as a pooled high-risk group on most HPV DNA test panels used in Canadian labs	Colposcopy if concurrent abnormal cytology (LSIL or higher); repeat co-testing in 12 months if cytology normal
Low-Risk Types 6 & 11	Cause approximately 90% of genital warts (condylomata acuminata); rarely associated with cancer	Not routinely targeted by cervical HPV DNA test; detected only on extended panels or separate genital swabs	Treatment of visible warts with topical therapies (imiquimod, podophyllotoxin) or procedural removal; no cancer surveillance required
Persistent High-Risk HPV (any type, 12+ months)	Significantly elevated risk of high-grade cervical intraepithelial neoplasia (CIN 2/3) and progression to invasive cervical cancer	Identified through repeat HPV DNA test showing same high-risk type at follow-up interval	Colposcopy and biopsy; potential treatment with LEEP or cold-knife conization depending on histology findings
Negative HPV DNA Test Result	Very low short-term risk of cervical cancer; high negative predictive value (>99%) for CIN 3 or worse	No high-risk HPV DNA detected; most reassuring result for cervical cancer screening purposes	Routine screening interval extended to 5 years per Canadian cervical cancer screening guidelines for ages 25–69

HPV stands for human papillomavirus. It is a group of related viruses spread through sexual contact, including vaginal, oral, and anal sex. Most people who are sexually active will carry some form of HPV at some point in their lives.

An HPV DNA test uses a method called polymerase chain reaction (PCR). PCR detects the genetic material of the virus in a cell sample. This tells your doctor exactly which type of HPV is present — and how risky it is.

Why HPV Genotyping Matters

Not all HPV strains carry the same risk. There are over 100 types of HPV, and they fall into two broad groups: low-risk and high-risk.

Low-Risk HPV Strains

Low-risk strains include HPV types 6, 11, 42, 43, and 44. These types usually cause genital warts. However, they rarely lead to cancer. Genital warts appear as small bumps or clusters around the genitals or anus.

High-Risk HPV Strains

High-risk strains include HPV types 16, 18, 31, 33, and 36. These strains are strongly linked to cervical cancer. They can also raise the risk of penile, anal, and other genital cancers. Identifying these strains early is a key reason to get an HPV DNA test.

According to the World Health Organization (WHO), HPV types 16 and 18 alone cause around 70% of cervical cancers worldwide.

Who Should Get an HPV DNA Test in Canada?

Canadian health guidelines recommend routine HPV testing for women and people with a cervix. Sexually active individuals with multiple partners should also speak with their doctor about regular STI screening.

Recommended Age and Frequency

Current guidance suggests the following schedule for cervical cancer screening that includes an HPV DNA test:

• Ages 25 to 49: Get tested every 3 years.
• Ages 50 to 64: Get tested every 5 years.

These intervals may vary slightly depending on your province or territory. Your family doctor or walk-in clinic can confirm which guidelines apply in your area.

Other Groups Who May Benefit

Your doctor may recommend an HPV DNA test even if you have no visible warts or symptoms. The virus can be present without any signs at all. Furthermore, the test can detect high-risk strains that a physical exam alone cannot identify.

Men who are sexually active, especially those with multiple partners, should also talk to their healthcare provider about STI screening options.

How the HPV DNA Test Works

The test is straightforward and quick. A healthcare provider collects a small sample of cells, usually from the cervix during a pelvic exam. The sample is sent to a lab for PCR analysis.

Preparing for the Test

To get the most accurate results, follow these steps before your appointment:

• Avoid vaginal creams or deodorant sprays for at least 48 hours before the test.
• Avoid sexual activity for 24 to 48 hours before the test.
• Empty your bladder just before the exam.

Always follow the specific instructions your doctor gives you. These steps help avoid interference with the sample.

What Happens in the Lab

Lab technicians use PCR technology to look for HPV genetic material in your sample. This method is highly sensitive. Therefore, it can detect even small amounts of the virus. Results usually return within a few days to two weeks, depending on the lab.

HPV DNA Test vs. Pap Smear: What Is the Difference?

You may have heard of the Pap smear (also called a Pap test or Papanicolaou test). Both tests play a role in cervical cancer screening, but they work differently.

A Pap smear looks at cervical cells under a microscope. It checks for abnormal cell changes that could lead to cancer. An HPV DNA test, on the other hand, looks for the virus itself — not just cell changes.

These two tests work well together. If a Pap smear shows abnormal cells, your doctor may order an HPV DNA test to find out whether HPV is causing those changes. In some provinces, both tests are done at the same appointment.

Learn more about how these tests compare at the Mayo Clinic’s cervical cancer screening resource.

How Does HPV Spread?

HPV spreads through skin-to-skin sexual contact. This includes vaginal, anal, and oral sex. You do not need to have penetrative sex to contract HPV. Even genital touching can spread the virus.

In rare cases, a pregnant person can pass HPV to their baby during a vaginal birth. However, this is uncommon. Most babies born to HPV-positive parents do not develop complications.

HPV is so widespread that most sexually active people will carry it at some point. Many people clear the infection on their own without treatment. However, some strains persist and can cause serious health problems over time.

Can HPV Be Prevented?

Yes. The HPV vaccine offers strong protection against the most dangerous strains, including types 16 and 18. In Canada, HPV vaccination is part of publicly funded school-based programmes in every province and territory.

The vaccine works best before a person becomes sexually active. However, it still offers benefits for older teens and adults. Talk to your family doctor about whether the HPV vaccine is right for you or your child.

Using condoms consistently also reduces the risk of HPV transmission. However, condoms do not cover all areas where HPV can spread, so they do not offer complete protection.

When to See a Doctor

You should speak with your family doctor or visit a walk-in clinic if any of the following apply to you:

• You are between 25 and 64 and have not had an HPV DNA test or Pap smear recently.
• You notice unusual growths, bumps, or warts in your genital area.
• You have had a recent sexual partner who tested positive for HPV.
• You have received an abnormal Pap smear result.
• You have multiple sexual partners and want to review your STI screening options.

In Canada, most routine screening visits are covered by provincial health plans. You do not need a referral to discuss STI testing with your family doctor or at a walk-in clinic. Early detection is always the best approach.
