What this test measures
A high-risk HPV genotyping test uses PCR or hybrid-capture technology to detect DNA from oncogenic (cancer-causing) HPV strains in cervical cells collected by a clinician. Most modern assays identify 14 high-risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68) and specifically separate-report HPV 16 and HPV 18 — together responsible for about 70% of cervical cancers. The remaining 12 high-risk types are reported as a pooled positive / negative.
The sample is collected as part of a routine pelvic exam — the clinician inserts a speculum and uses a brush to collect cells from the transformation zone of the cervix. The sample is placed into a liquid-based cytology vial, which doubles up for HPV DNA testing and Pap smear interpretation. Sometimes the test is done as a stand-alone HPV-only test or as a co-test with Pap cytology.
Why it matters
Cervical cancer is one of the most common cancers in Indian women — roughly 75,000 deaths each year. It is almost entirely caused by persistent high-risk HPV infection, and is one of the most preventable cancers when detected at the pre-cancer (CIN 1–3) stage. WHO has launched a global cervical cancer elimination initiative targeting HPV vaccination + screening + treatment of pre-cancers.
HPV testing is now the preferred primary screening test internationally (WHO, ACS) because it is more sensitive than Pap cytology and detects pre-cancers earlier. A negative HR-HPV at 30+ is reassuring enough that screening intervals can stretch to 5 years. A positive test triggers reflex Pap or colposcopy depending on the genotype and patient age.
How to prepare
Schedule the test for a time when you are not menstruating — ideally 10–14 days after the start of your last period. Avoid vaginal intercourse, vaginal medications, douching, spermicides and tampons for 48 hours before the test. The sample is collected by your gynaecologist during a routine pelvic exam (3–5 minutes). Mild spotting after the sample is normal. Mention any history of cervical procedures (LEEP, conisation), HPV vaccination, and previous abnormal Pap results.
Markers & reference ranges
Reference ranges below are typical adult values. Your lab's reported range may differ slightly based on the assay platform and patient demographics — always read your report against the range printed on it.
| Marker | Normal range | If low | If high |
|---|---|---|---|
| HPV 16 DNA (—)[1][2] | Not detected | Not detected — HPV 16 absent. | Detected — highest oncogenic risk. HPV 16 alone causes ~50% of cervical cancers. Persistent infection → colposcopy regardless of Pap result. |
| HPV 18 DNA (—) | Not detected | Not detected. | Detected — second-highest oncogenic risk. HPV 18 causes ~20% of cervical cancers, particularly adenocarcinoma. Persistent infection → colposcopy. |
| Other 12 high-risk types (pooled) (—) | Not detected | Not detected. | Detected — moderate oncogenic risk. Most clear within 1–2 years without treatment. Persistent positivity at 12 months → colposcopy. Reflex Pap cytology is often done to triage. |
HPV test results and next steps (general guidance)
| Result | Risk | Typical next step |
|---|---|---|
| All HR-HPV negative | Very low | Repeat screening in 3–5 years (per local guideline) |
| HPV 16 positive | High | Colposcopy regardless of Pap |
| HPV 18 positive | High | Colposcopy regardless of Pap |
| Other 12 HR-HPV positive | Moderate | Reflex Pap cytology; colposcopy if Pap abnormal or persists at 12m |
| HR-HPV positive + abnormal Pap | High | Colposcopy |
Frequently asked questions
Is HPV testing different from a Pap smear?
Yes. A Pap smear looks at cervical cells for abnormalities under the microscope (cytology). An HPV test detects the virus DNA. HPV testing is more sensitive for detecting pre-cancers; Pap is more specific. Modern guidelines often use HPV as the primary test, with Pap as a triage / co-test.
I am vaccinated against HPV — do I still need this test?
Yes. HPV vaccines protect against the most important high-risk types but not all of them. Cervical screening (Pap or HPV) is still recommended on the same schedule as for unvaccinated women.
When should I start cervical cancer screening?
WHO recommends HPV-based screening starting at age 30 (earlier in HIV-positive women). ACS recommends starting at 25. Indian guidelines vary; ICMR recommends starting at 30 with HPV or visual inspection methods.
How often should I do an HPV test?
A negative HR-HPV test allows a 3–5 year interval (depending on age and guideline). After a positive result, follow-up intervals depend on genotype, Pap findings, and colposcopy biopsy results.
I tested positive for HPV — does that mean I have cancer?
No. Most HPV infections clear on their own within 1–2 years without treatment. Persistent infection (especially with HPV 16 / 18) raises the risk of pre-cancerous changes (CIN). The test is a warning to watch carefully, not a cancer diagnosis.
How long does the report take?
Most NABL labs deliver HPV PCR results in 5–7 days.
Can the test be done at home?
Cervical sample collection requires a speculum exam by a clinician. Zelnoo can arrange the consultation at partner clinics in Mumbai and Thane.
