HPV Test: How to Read It, Types 16 and 18, and a Positive Result

Your report shows "HPV" — and the first thought is: is this cancer? Stay calm. Human papillomavirus (HPV) is a very common infection: most sexually active people are infected at some point, and in 90% of cases the body clears the virus on its own within 1–2 years. The HPV test is not there to scare you but to catch in time the types that, with long-term persistence, raise the risk of cervical cancer. Here is what the test shows and how to read the result. More on the virus, its types and prevention is in HPV: cancer risk.

What HPV Is and Why the Test Is Done

HPV is a group of more than 200 virus types. Some cause warts and papillomas (low oncogenic risk), while about 14 types are classed as high-risk — with years of persistence they can cause precancer and cervical cancer, and less often other sites. The aim of the HPV test is to detect exactly these high-risk types so the cervix can be monitored if needed. Finding HPV is not a cancer diagnosis — it is a signal to follow up.

HPV Types: High-Risk (16, 18) and Low-Risk

The high-risk types are 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68. Of these, types 16 and 18 are the most dangerous: they account for about 70% of cervical cancers, so modern tests report them separately (genotyping). Low-risk types (6, 11) cause anogenital warts but not cancer. So the result matters not just as "HPV detected" but which types specifically.

HPV Test and Cytology (Pap Smear): Reading Them Together

The HPV test (PCR) shows whether the virus is present, while cytology (Pap smear) shows whether cervical cell changes have already appeared. Current guidelines make the HPV test the preferred screening method from age 30, often together with cytology (co-testing). The combination of "which virus + are there cell changes" is more accurate than either alone and determines the follow-up plan.

What a Positive HPV Result Means

A positive result means you carry the virus — but NOT cancer and not a sentence. The next steps depend on the type and cytology:

• High-risk HPV + normal cytology → usually monitoring and a repeat in 6–12 months (the virus often clears on its own).
• HPV 16/18 or abnormal cytology → the gynaecologist refers you for colposcopy to examine the cervix in detail. HPV is often tested alongside other infections — HIV, hepatitis B and hepatitis C; the decision on further work-up is made by the doctor.

Normal and Negative Result

Normal means no high-risk HPV detected. A negative result indicates low risk for the coming years — which is why HPV-based screening intervals are longer than with cytology alone. Note: a single negative test does not cancel future routine screening.

Prevention: Vaccination and Screening

The main prevention of cervical cancer is HPV vaccination (most effective before sexual debut) and regular screening. Condoms reduce but do not eliminate transmission. Not smoking also lowers the risk of viral persistence.

When to See a Doctor

See a gynaecologist for a positive high-risk HPV result (especially 16/18), abnormal cytology, or bleeding between periods or after contact. Do not interpret the result alone: the plan (monitoring, colposcopy) is set by the doctor based on the virus type, cytology and history. In most cases HPV clears on its own, and regular screening reliably prevents cancer.
