HPV Testing Results Explained: What Your Results Mean
HPV test results explained: what negative, positive, genotype 16/18, and Aptima positive results mean, and what steps to take after each outcome.
Getting your HPV test results back can feel disorienting. The report uses clinical language, the categories don’t always map to what you expected, and the internet is full of alarming information that doesn’t quite fit your situation. Human papillomavirus is the most common sexually transmitted infection in the United States, affecting tens of millions of people at any given time, yet most people receive their results with little explanation of what the terms actually mean.
The good news: most HPV infections clear on their own. The important part is understanding what your specific result tells you, because “HPV positive” covers a wide range of outcomes, and “HPV negative” doesn’t mean you can skip future screening. Knowing the difference between a low-risk and high-risk strain, between genotype 16/18 and other high-risk types, between a colposcopy referral and a routine repeat test, puts you in a position to act with clarity rather than react with fear.
This post walks through each result category, what the clinical terms mean in plain language, and what questions to ask your provider next.

What Is HPV Testing and How Does It Work?
HPV testing looks for high-risk strains of human papillomavirus in cervical cells. There are more than 200 known HPV types. About 14 are classified as high-risk, meaning they have the potential to cause cellular changes that, if left unmonitored over years, can progress to cervical cancer. Low-risk types may cause genital warts but don’t carry the same cancer risk.
Two main testing platforms are used in clinical practice. DNA-based testing detects viral DNA directly. RNA-based testing, commonly called HPV Aptima, detects E6/E7 mRNA, the viral proteins responsible for driving abnormal cell changes. The mRNA test is considered more specific: it’s more likely to flag an infection actively expressing the genes linked to cancer progression, rather than a transient infection already clearing. According to the National Institutes of Health, primary HPV testing may outperform Pap smears alone in detecting high-grade cervical precancer, which is why co-testing and HPV-first screening protocols have become standard in many clinical guidelines.
“HPV is so common that nearly all sexually active people get it at some point in their lives. In most cases, HPV goes away on its own and does not cause any health problems.”
Co-testing, where a Pap smear and HPV test run simultaneously, remains common. But knowing which test platform your provider used matters when interpreting results. Ask whether your result came from a DNA or mRNA assay. It affects how your provider will manage an abnormal finding.
How to Read HPV Test Results
Your HPV test result will typically fall into one of three categories: negative (not detected), positive for high-risk HPV without further genotyping, or positive with genotyping that identifies whether HPV 16 or 18 is present. Each carries a different clinical response, and your Pap result at the same visit often drives the decision about what comes next.
Here’s a breakdown of the most common result categories and what each one means clinically:
- Negative / Not Detected: No high-risk HPV strains were found. If your Pap was also normal, routine screening in 3 to 5 years is standard depending on your age and history.
- High-Risk HPV Positive, Not 16/18: A high-risk strain other than 16 or 18 was detected. Management depends heavily on your Pap result at the same visit.
- HPV 16 Positive: The highest-risk genotype. Colposcopy is typically recommended regardless of Pap result.
- HPV 18 Positive: Second highest risk. Also usually leads to a colposcopy referral.
- HPV Aptima Positive: E6/E7 mRNA was detected, indicating an infection actively expressing cancer-related proteins. Next steps depend on genotype and concurrent Pap findings.
- ASC-US with Positive HPV: Mild Pap cell changes alongside a positive HPV result. Usually prompts colposcopy.
Jenna Hardy, who covers evidence-based HPV and cervical screening on this site, emphasizes that the most common source of patient confusion is receiving a positive HPV result alongside a normal Pap. It feels contradictory. It’s actually a defined, manageable clinical scenario with a clear monitoring protocol behind it.
What Does “HPV Not 16/18 Detected” Mean?
This result means a high-risk HPV type was found, but it was not genotype 16 or 18. Still a finding worth following, but it carries a lower immediate risk of cancer progression than a 16 or 18 positive result.
Clinically, what happens next depends almost entirely on your Pap result from the same visit. If your Pap was normal and you’re 30 or older, your provider will likely recommend a repeat co-test in one year. If two consecutive annual tests confirm the same finding without clearance, colposcopy may then be warranted. If your Pap showed any cell abnormalities, including ASC-US, LSIL, or higher, the threshold for colposcopy referral is lower.
This category of result should not be dismissed. But it also shouldn’t cause alarm. The body clears most high-risk HPV infections within one to two years without any intervention. Regular monitoring is how providers catch the minority of cases that don’t clear.
HPV Positive But 16 and 18 Negative: What Happens Next?
If your result shows HPV positive but with 16 and 18 specifically negative, you have one of the 12 other high-risk genotypes, which carry meaningful but comparatively lower cancer risk. Your management path follows the same logic as above: your Pap result drives the next clinical decision.
Many providers now use the ASCCP 2019 risk-stratified guidelines rather than a simple result-specific algorithm. Under those guidelines, your provider calculates your immediate risk of cervical precancer based on your current results AND your prior screening history. A woman with a prior normal co-test who now has a new high-risk HPV positive (not 16/18) result may simply be monitored with a repeat test in 12 months. Someone with a history of prior abnormal results faces a lower colposcopy threshold, even with the same current result.
This is exactly the kind of nuance worth discussing with your provider directly, rather than interpreting from a results portal alone. For research-based information on HPV and cervical health screening guidelines, Lesbian STD covers each step of the cervical screening pathway in plain clinical language.
Can HPV Tests Detect Cancer?
HPV tests don’t detect cancer directly. They detect the presence of viral strains known to cause cancer. The virus itself isn’t cancer. But persistent infection with a high-risk type causes cervical cell changes that, if unmonitored, can progress to precancerous lesions and, over the course of years to decades, to cervical cancer.
The distinction matters because it explains why a positive result doesn’t mean you have cancer, and why the follow-up testing system exists. It typically takes 10 to 20 years for high-risk HPV infection to progress from initial exposure to invasive cervical cancer, which is precisely why regular screening is so effective. The Pap smear is what directly evaluates cervical cells for abnormal changes. A positive HPV test triggers closer surveillance of those cells, giving providers a wide window to intervene at the precancerous stage, when treatment is simpler and outcomes are significantly better.
What Is the Most Concerning Pap Result?
The most concerning Pap result is a high-grade squamous intraepithelial lesion (HSIL) or atypical glandular cells (AGC). HSIL indicates significant cellular changes with a meaningful probability of progression to cancer without treatment. AGC is flagged because glandular cell abnormalities can indicate pathology in the endocervix or endometrium rather than just the outer cervix surface.
HSIL combined with a positive HPV test, especially HPV 16, is the scenario that warrants the fastest clinical response. Colposcopy is typically scheduled within weeks, and biopsy-confirmed CIN 2 or CIN 3 lesions are usually treated with LEEP (loop electrosurgical excision procedure) or cone biopsy.
“High-grade squamous intraepithelial lesion (HSIL) means there are significant cell changes on the cervix. This result requires follow-up with colposcopy to look for precancerous or cancerous cells.”
For context, less severe results like ASC-US or LSIL are concerning enough to monitor but don’t carry the same urgency. Knowing where your result sits on this spectrum helps you understand your provider’s timeline. More detailed guidance on cervical health and STI screening for women is available through Lesbian STD’s clinical education resources.
Warning Signs That Warrant Prompt Follow-Up
Most HPV infections, even mild Pap abnormalities, produce no symptoms at all. That’s what makes regular screening so essential. But if you have a recent abnormal result and experience any of the following, contact your provider rather than waiting for your scheduled follow-up appointment:
- Unusual vaginal bleeding, especially between periods or after sex
- Pelvic pain that doesn’t resolve with normal cycle changes
- Watery, foul-smelling, or blood-tinged vaginal discharge
- New or worsening pain during sex
- Visible lesions or unusual growths in the genital area
- Any spotting after menopause, regardless of amount
None of these is specific to HPV alone. But in the context of a recent abnormal cervical result, any one of them should prompt earlier evaluation. Don’t wait for the repeat test date if your symptoms have changed.

What to Expect: A Realistic Post-Result Timeline
Timelines vary by result severity. Here’s a general framework for what the monitoring process looks like in practice, based on standard screening guidelines:
- Negative HPV + Normal Pap (ages 30 to 65): Routine co-testing in 5 years. No action needed in the interim.
- High-Risk HPV Positive (Not 16/18) + Normal Pap: Repeat co-test in 12 months. If still positive at one year, colposcopy referral follows.
- HPV 16 or 18 Positive: Colposcopy typically recommended within weeks, regardless of Pap result.
- ASC-US + HPV Positive: Colposcopy recommended. If ASC-US with HPV negative, repeat testing in one year.
- LSIL: Colposcopy for most non-pregnant adults. Closer monitoring with 1 to 2 year repeat testing in certain low-risk categories.
- HSIL: Prompt colposcopy. Biopsy-confirmed CIN 2 or CIN 3 is typically treated within weeks to a few months of confirmed diagnosis.
The system is designed to catch problems early, and most women who enter the monitoring pathway never progress to cancer. Treatment of precancerous cervical lesions is highly effective, with success rates above 90% for CIN 2/3 when treated appropriately. Early detection reduces complications, which is precisely why the screening cadence matters.
Pro tip: Keep a personal record of your Pap and HPV results over time, including the test platform used (DNA vs. mRNA). This history helps your provider apply risk-stratified guidelines more accurately, especially if you change providers or move between clinics.
Understanding your HPV test result is not about managing fear. It’s about having the right information to make the next move with clarity. A positive result, even for a high-risk type, is a signal that the screening system worked. The path from here is follow-up, monitoring, and if needed, treatment of an early finding rather than a late one. Board-certified providers and public health professionals designed these protocols to give women a real window to intervene well before cancer develops, and that window only stays open when screening continues on schedule.
