HPV Test & HPV DNA Test: Procedure, Results, Cost & Cervical Cancer Screening

Overview

Cervical cancer is a type of malignancy that starts in the cervix, which is the narrow part of the uterus.1,32,000 new cases of cervical cancer are diagnosed every year in India. In fact, it is the third most common type of cancer affecting Indian women, accounting for nearly 18.3% of all female cancer cases in our country.

Most cases of cervical cancer are preventable. This is possible with the help of HPV vaccination, regular cervical cancer screening, including HPV tests and HPV DNA tests, and timely medical intervention.

Cervical cancer screening can help to detect the early traces of cancer. HPV test can help detect high-risk human papillomavirus that can cause changes in the cervical cells and increase the chances of cervical cancer. HPV DNA test, on the other hand, is a molecular test that can help to detect the traces of any genetic material associated with high-risk HPV.

Are you planning to undergo HPV screening as well?

It is quite natural to have questions about the procedure, how to prepare, the test results, and the costs involved. This blog will help you answer all the questions related to the procedure so that you can make an informed medical decision.

What Is An HPV DNA Test?

A human papillomavirus test is a simple screening test that helps to trace any high-risk types of viruses in the sample of cells collected from the cervix. This is the lower part of the uterus where it connects with the vagina.

Human papillomavirus is a very common group of viruses, and in many cases, the infection goes away on its own without causing any major health problem.

HPV DNA test is a screening test for cervical cancer. It helps to detect the DNA traces of high-risk human papillomavirus from a collected cervical cell sample.

Some tests may also help to identify the type of HPV, while others can help to figure out whether one or more high-risk types have been found.

Why Is HPV DNA Testing Important?

HPV DNA testing is important because it can help to identify high-risk strains of HPV even before there is any visible cellular damage or precancerous changes. It can support early intervention, reduce the likelihood of missed high-risk infections and help doctors determine whether additional tests or follow-up are necessary.

World Health Organisation guidelines for screening and treatment of cervical pre-cancer lesions for cervical cancer prevention recommend DNA-based HPV testing as a first-choice screening method.

What Is The Difference Between An HPV Test And A Pap Test?

Both HPV tests and a Pap test are screening tests for cervical cancer. Both use different techniques and are used to look for different things.

HPV test is used to detect any traces of high-risk HPV infection, whereas a Pap test is done to look for any cellular abnormalities that may indicate cancer.

Feature HPV test / HPV DNA test Pap test
What it detects High-risk HPV infection traces Abnormal/unusual changes in cervical cells
Sample The cell sample is collected from the cervix The cell sample is collected from the cervix
Main purpose This helps to identify high-risk human papilloma virus that can lead to cervical cancer This helps to identify any Malignant or precancerous changes in the cell sample
Result It helps to detect the presence or absence of HPV as well as to identify certain high-risk types It helps to identify normal or unusual cellular changes
Role in screening This is used as a primary screening test as per WHO This can be used as a primary screening test as well as during follow-ups
Follow-up Depends on HPV type, screening history and other findings Depends on the type and severity of cellular changes

Your doctor can even recommend an HPV and Pap smear test together. This is commonly known as co-testing.

Who Should Consider HPV Screening?

According to the WHO guidelines, an HPV screening test is recommended for people with a cervix, belonging to specific age groups or risk categories.

Population Group Recommended Age Screening Interval Primary Test Type
Ages 21–29 Age 21 After every 3 years Pap smear
Ages 30–65 Age 30 After every 5 years HPV test alone or co-test with Pap
Age 65+ N/A No need if the tests are normal None (if previously negative)
HIV-Positive / Immunocompromised Age 25 After every 3 to 5 years (Can be more frequent if doctor advises) HPV or co-testing per doctor guidance

A personalised screening and surveillance plan may also be recommended for people with a history of abnormal cervical screening test results in the past, as well as those with conditions that affect the immune system.

You may wish to discuss HPV screening with your gynaecologist if:

  • You are going for a routine cervical cancer screening.
  • You have never gone for cervical cancer screening before.
  • You have undergone a Pap or HPV test in the past, but the results were not normal.
  • Your previous Pap or HPV tests indicated precancerous lesions
  • You're suffering from a condition that affects the immune system.

HPV Test Procedure: What Happens During the Test?

The HPV test is a simple procedure and can take about a couple of minutes. It involves the collection of cell samples from the cervix for laboratory analysis.

Step 1: Consultation with the doctor

The first step of the process is to consult your doctor, who will ask about your medical history. This information helps your doctor to understand whether you Just need the routine screening or a more elaborate evaluation

Step 2: Positioning for the examination

In order to collect the sample, you will be required to lie down on the examination table with your knees bent. Doctors use a speculum to open the vagina and access the cervix for collection of the sample. You might feel slight discomfort, but there is no pain.

Step 3: Collection of the sample

Once the doctor has a clear view, they use a small brush to collect a sample of tissues and cells from the cervix. The sample is then carefully stored and sent to the laboratory.

Step 4: Laboratory testing

In the laboratory, the technicians use various molecular methods and techniques to detect any high-risk HPV genetic material. More detailed techniques may be used to detect the type of HPV.

Step 5: Receiving your results

Once your doctor has the results, they will explain the findings and help you understand what your next step should be, whether you need further evaluation or follow-up, or if you need any repeat testing.

Important

It is important to note that the time taken to receive the results may vary depending upon the laboratory, the hospital, the testing facilities, and the type of tests. There is no standard time for this.

How To Prepare For An HPV Test

Here are a few things that you need to keep in mind while preparing for an HPV test.

  • Inform your doctor if you are taking any medication or using any ointments, especially in the vaginal area. This is important, as you might need to stop taking these before the test.
  • If possible, make sure that you are not menstruating when your test is scheduled. Discuss this with your healthcare professional.
  • Let your doctor know if you are pregnant or even if you suspect that you might have conceived.
  • If you have had an HPV test or Pap smear test in the past, share the details with your doctor.
  • If you have had a pelvic examination in the past and have experienced difficulty in tolerating it, let your healthcare professional know.

HPV Test Results: What Do Positive and Negative Results Mean?

1. Negative HPV test result

If your HPV test is negative, it means that there were no high-risk HPV types detected in your sample. A negative HPV test does not completely eliminate the future risks of cervical cancer. It does suggest that your risk of developing it is quite low.

2. Positive HPV test result

If your HPV test is positive, it means that doctors have found one or more high-risk HPV types in your sample. While this does not necessarily mean that you have cervical cancer, it does put you at a high risk. It calls for the need for immediate medical intervention.

Following a positive HPV test result your doctor may recommend:

  • Additional assessment of the cervical cells.
  • A Pap test or another appropriate triage test.
  • Repeat HPV testing after a specified interval.
  • Colposcopy, which allows the cervix to be examined more closely.
  • A cervical biopsy if clinically indicated.

3. HPV 16 or HPV 18 detected

Both HPV 16 and HPV 18 are high-risk types and major contributors to cervical cancer cases. If either of the two has been detected, you need to immediately consult a doctor and take necessary measures.

4. Unsatisfactory or invalid result

If the test results are unsatisfactory or invalid, the sample may be collected again and analysed. Unsatisfactory results do not necessarily indicate cervical cancer.

An unsatisfactory result does not automatically mean that an abnormality or cancer is present.

HPV Test Cost In India

Cost of an HPV test in India lies anywhere between 1,000 and 5,500 and varies depending on the hospital, diagnostic laboratory, testing method, as well as several other factors. These include:

  • Type of test:  A high-risk HPV DNA test, an HPV test with genotyping and combined HPV/Pap testing may have different prices.
  • Laboratory method: The technology and test panel used can affect the charge.
  • Consultation fees: A gynaecology consultation may be billed separately.
  • Additional investigations: A Pap test, colposcopy or biopsy may increase the overall cost if required.
  • Location and facility: Prices may differ between hospitals, standalone laboratories and cities.

How much does an HPV DNA test cost?

The cost of an HPV DNA test in India is almost the same as that of an HPV test, and it is somewhere around ₹1,000 to ₹5,500. The best way to find out is to confirm it with the hospital before booking. You can also ask about sample collection, consultation, and any other important information to make the whole process hassle-free.

By now, you must have understood the importance of cervical cancer screening and how HPV tests and HPV DNA tests help in identifying the early signs of cancer. This not only helps in the early detection and prevention but also in the effective management of cervical cancer, thereby helping to improve the survival rates and overall quality of life.

If you are due for screening or have concerns about previous results, consult a qualified healthcare professional to determine the most appropriate next step.
