Abnormal Cells but HPV Negative — What It Means
This is one of the more reassuring combinations a cervical screening report can produce, even though it does not read that way at first glance. Almost all cervical cancer is driven by persistent high-risk HPV infection. If the virus is not detectable in your sample, the chance that the abnormal-looking cells represent significant precancer drops sharply — and there is a long list of ordinary, benign reasons for cells to look unusual under a microscope. Abnormal appearance is not the same as precancer. This page explains how the two results are read together, why cells change without HPV, the small number of reports that are still investigated regardless of the virus result, and what your next test should be.
- The virus result carries the weight — no high-risk HPV makes significant precancer far less likely
- Cells change for ordinary reasons — infection, inflammation, menopause, a coil, healing after a procedure
- Some reports are still looked at — high-grade or glandular cytology goes to colposcopy whatever the HPV says

Why This Combination Is Usually Good News
Two different tests can be run from the same brush sample. Cytology looks at the shape and appearance of the cells. The high-risk HPV test looks for the DNA of the virus that causes cervical precancer in the first place. When they disagree — cells that look unusual, virus that cannot be found — the virus result generally wins the argument, and for a straightforward reason: the disease pathway runs through the virus. Without persistent high-risk HPV, the biological engine that turns normal cervical cells into precancer and then into cancer is not running.
That is why screening programmes worldwide have moved to HPV-based testing as the primary test, with cytology used to sort out what to do about a positive result rather than the other way round. Our guide to how HPV leads to cervical cancer explains the mechanism, and the HPV test compared with a Pap smear sets out what each one can and cannot tell you.
- A negative high-risk HPV test is a strong negative. It is the single most useful piece of information on a screening report, and it stays informative for years rather than weeks.
- “Abnormal cells” is a wide phrase. It covers everything from a borderline judgement call on a handful of cells to a definite high-grade change, and those two ends of the range are managed completely differently.
- Most low-grade abnormalities with negative HPV are reactive. The cervix responds visibly to irritation, infection and hormones, and cytology reports what it sees.
- A negative result is not a discharge. You return to screening at the interval your doctor sets, which may be shorter than usual after an abnormal cytology report.
- It does not rule everything out. A small number of cytology reports are investigated regardless of the HPV result — those are set out below, honestly.
Why Cells Can Look Abnormal When There Is No HPV
Cytology reports appearance. Plenty of everyday things change how cervical cells appear without any precancerous process being involved.
Inflammation and Infection
Bacterial vaginosis, thrush, trichomonas and ordinary cervicitis all irritate the cervix. Inflamed cells enlarge, their nuclei change, and a cytologist correctly reports them as not normal. Treating the infection usually returns the picture to baseline.
Atrophic Change After the Menopause
Falling oestrogen thins the cervical and vaginal lining. The cells become smaller and more tightly packed, which can closely mimic abnormality on a slide. This is one of the commonest reasons for an abnormal-looking smear with a negative HPV result in older women.
Repair and Reactive Change
Cells regenerating after childbirth, after an infection, or after a previous cervical procedure look busy and immature under the microscope. This is healing, not disease, and it settles on its own.
Intrauterine Device in Place
A coil produces a recognisable set of cellular changes, including glandular cells that can look atypical. Cytologists are alert to it, but it is a frequent explanation for a borderline report in a woman with a device fitted.
Cervical Ectropion and Polyps
Softer glandular cells sitting on the outer cervix, or a benign polyp, shed cells that look different from the surrounding surface. Both are harmless and both are visible on examination.
Sampling and Slide Factors
Blood, lubricant, air-drying and a thin sample all degrade how cells appear. Where the sample is called unsatisfactory rather than abnormal, this is a comment about the slide, not about you.
ASCUS — the Honest “Not Sure”
Atypical squamous cells of undetermined significance is cytology admitting it cannot classify what it sees. Paired with a negative HPV test, this combination is generally managed by repeating the screen rather than by colposcopy.
Genuine Low-Grade Change
A true low-grade abnormality can be present as the tail end of an infection the body has already cleared. The change usually resolves by itself, which is why observation rather than treatment is standard for low-grade disease.
If you are trying to decode the terminology on the report itself — ASCUS, LSIL, HSIL, AGC — our full guide to an abnormal Pap smear result and what happens next takes each term in turn.
When a Negative HPV Test Is Not the End of the Conversation
Being straight with you matters more here than being comforting. There are four situations in which an abnormal cytology report is investigated even though high-risk HPV was not detected.
1. High-grade change reported on cytology (HSIL)
If the cytologist has read the cells as high-grade, that report is acted on regardless of the virus result. A negative HPV test alongside high-grade cytology is uncommon and usually means one of the two results needs re-examining — so both the slide and the cervix get looked at properly, with colposcopy and a directed biopsy.
2. Glandular abnormality (AGC or atypical glandular cells)
Glandular cells come from inside the cervical canal or from the lining of the uterus, and an abnormality among them is investigated on its own merits. Some cervical adenocarcinomas are not driven by HPV at all, and an atypical glandular report can also reflect a problem in the endometrium rather than the cervix, which an HPV test says nothing about.
3. Symptoms that do not fit a benign explanation
A screening test is not a diagnostic test. Bleeding after sex, bleeding after the menopause, or a persistent unusual discharge is examined on its own account, and a negative HPV result does not cancel that. If any of those apply to you, read our guide to abnormal vaginal bleeding and get the cervix looked at.
4. A previously treated cervix or reduced immunity
Women being followed up after treatment for precancer, and women whose immune system is suppressed by HIV or by medication, are managed on their own protocols. Thresholds are lower and intervals are shorter for both groups, so a borderline report is more likely to lead to a closer look.
The honest limits of the test. An HPV result reflects the sample that reached the laboratory. If the sample was thin, taken during heavy bleeding, or missed the transformation zone, the result is less informative than the report makes it sound. Laboratory panels also target the high-risk types responsible for the overwhelming majority of disease, not every papillomavirus that exists. None of this makes a negative result unreliable — it makes the case for keeping the next scheduled test rather than treating one negative as permanent.

A Report Is Not an Answer Until Someone Explains It
Cytology, HPV testing and colposcopy are all available in-house at CION, with same-week appointments across Hyderabad and a woman doctor available on request.
What Happens Next
For most women reading this page, the answer is a repeat test at a defined interval and nothing else. The steps below describe how that decision gets made.
Step 1 — The two results are read together, not separately
Your doctor should look at the exact cytology wording and the HPV result side by side. Borderline or low-grade cytology with a negative high-risk HPV test sits in the low-risk group. High-grade or glandular cytology does not, whatever the HPV result says. This is the single most important part of the consultation, and it is the reason a report emailed without a conversation is unsatisfying.
Step 2 — Treat anything obvious and reversible
If an infection is present, it is treated. If the cervix is atrophic after the menopause, local oestrogen is sometimes used before repeating the sample so the cells are easier to interpret. Removing the irritant frequently removes the abnormal appearance, and a repeat smear then reads normally.
Step 3 — Repeat the screen, at an interval you are told
Low-risk combinations are generally managed with a repeat co-test rather than immediate colposcopy, because most reactive changes resolve. What matters is that you are given a date and a reason, not a vague instruction to come back sometime. Ask for it in writing.
Step 4 — Colposcopy where the report warrants it
High-grade cytology, glandular abnormality, symptoms, or persistent abnormality on repeat testing all lead to colposcopy — the cervix examined under magnification with a biopsy from anything that looks abnormal. Most women who have a colposcopy do not have cancer. In the uncommon event that a biopsy confirms invasive disease, the pathway is set out on our cervical cancer treatment in Hyderabad page, and every case at CION goes to a multidisciplinary tumour board before treatment is proposed, in line with NCCN, FIGO and ESMO guidance.
Your Cytology Wording, With HPV Negative
How each cytology report is generally read when the high-risk HPV test comes back negative. Your own management depends on your age, your history and your symptoms, and is set by your doctor rather than by a table.
| What the cytology says | How it is read with HPV negative | Usual next step |
|---|---|---|
| Reactive or inflammatory change | A benign response to irritation or infection, not a precancerous finding | Treat any infection; return to routine screening |
| Atrophic change | Thinning of the tissue after the menopause, mimicking abnormality | Local oestrogen is sometimes used, then the sample is repeated |
| ASCUS (borderline squamous cells) | Low risk. The commonest borderline report, and reassuring with negative HPV | Repeat co-test at the interval your doctor specifies |
| LSIL (low-grade change) | Usually the trace of an infection the body has already dealt with | Repeat testing; colposcopy if it persists |
| HSIL (high-grade change) | Acted on regardless of the virus result; the discordance itself is reviewed | Colposcopy with directed biopsy, without delay |
| AGC (atypical glandular cells) | Investigated on its own merits — the cervical canal and the endometrium both matter here | Colposcopy with endocervical sampling; endometrial assessment where indicated |
| Unsatisfactory or inadequate sample | A comment on the slide, not a finding about you | Repeat the sample after a short interval |
Whatever the wording, the interval to your next test should be a date you have been given, not a decision left to memory — see the cervical cancer overview for how screening fits into the wider picture.
Four Things This Result Does Not Mean
Reports get over-read in both directions. These are the misreadings we hear most often in clinic.
- It does not mean you have been unfaithful, or that anyone has. HPV is extremely common, often acquired years earlier, and frequently clears on its own. A negative result today says nothing whatsoever about anybody’s behaviour, and a positive one would not either.
- It does not mean you can stop screening. A negative HPV test is powerful but not permanent. New exposure is possible, and the interval to your next test exists for that reason. Women previously treated for precancer stay on their own longer schedule regardless.
- It does not mean symptoms can be ignored. Screening is for women without symptoms. Bleeding after sex, bleeding after the menopause or a persistent unusual discharge needs the cervix looked at, whatever the last report said.
- It does not mean the abnormal cells were a mistake. The cytologist reported what was on the slide. Something did change the appearance of those cells — usually inflammation, hormones or healing — and identifying which of those it was is a useful conversation, not a wasted one.
If you would value a second read of a report that has worried you, a free second opinion at CION covers exactly that: the cytology wording, the HPV result, an examination if it is warranted, and a written plan for what happens next.

Can I still have cervical cancer if my HPV test is negative?
It is very unlikely, and that is why the test is used. The World Health Organization puts the proportion of cervical cancers linked to high-risk HPV at around 99%, so removing the virus from the picture removes almost all of the risk. It is not an absolute guarantee: a small number of cervical adenocarcinomas are HPV-independent, and any test reflects the quality of the sample that reached the laboratory. That is why a negative HPV result does not override a high-grade or glandular cytology report, and does not override symptoms such as bleeding after sex or after the menopause. Those are examined on their own account.
What does ASCUS with a negative HPV test mean?
ASCUS means the cytologist saw squamous cells that did not look entirely normal but could not classify them as a definite abnormality — an honest "not sure" rather than a finding. It is the most common borderline report there is. Paired with a negative high-risk HPV test, it sits in the low-risk group, because the change is very unlikely to be precancerous without the virus that drives precancer. Standard management is a repeat screening test at an interval your doctor specifies rather than immediate colposcopy. Ask for that date in writing, and mention any symptoms, because symptoms are assessed separately from screening results.
Why did my smear show abnormal cells if I do not have HPV?
Because cytology reports how cells look, and many ordinary things change their appearance. Inflammation and infection make cells enlarge and their nuclei alter. Thinning of the tissue after the menopause packs cells together in a way that can closely mimic abnormality. Cells regenerating after childbirth, after an infection or after a cervical procedure look immature and busy. An intrauterine device produces its own recognisable changes. Blood, lubricant or a thin sample degrade the slide. None of these involve a precancerous process, and most settle on their own or once the underlying irritation is treated.
Do I still need a colposcopy if my HPV test came back negative?
Usually not, but it depends on what the cytology said. Borderline and low-grade reports with a negative high-risk HPV test are generally managed by repeating the screening test rather than by colposcopy. High-grade cytology is different: it is acted on regardless of the virus result, and the discordance between the two results is itself reviewed. Atypical glandular cells are also investigated on their own merits, because glandular abnormality can involve the cervical canal or the lining of the uterus. Symptoms, previous treatment for precancer, and a suppressed immune system all lower the threshold for looking.
When should my next test be if my smear was abnormal but HPV negative?
Sooner than a routine screening interval in most cases, but the exact timing depends on what the cytology said, your age, whether an infection was found and treated, and whether you have been treated for precancer in the past. What you should not accept is a vague instruction to come back sometime. Ask your doctor for a specific date and the reason behind it, and have it written down. At CION every screening review ends with the next test date recorded, so a plan that runs over months or years does not depend on anyone remembering it.
