HPV Test

What Is the HPV Test?

The HPV test is a screening test performed to detect the high-risk types of the HPV virus — short for Human Papilloma Virus — particularly those that can lead to cervical cancer. HPV is one of the most common sexually transmitted infections and often causes no symptoms. However, some high-risk HPV types can, over many years, cause changes in cervical cells that may progress to cancer.

By detecting these risky virus types at an early stage, the HPV test makes it possible to take precautions before cancer develops.

For What Purposes Is the HPV Test Performed?

The HPV test is performed for the following purposes:

• To determine the risk of cervical cancer at an early stage
• To detect precancerous cellular changes
• To evaluate abnormal smear test results
• To carry out routine screening in women over 30

In most women, HPV infection is cleared by the immune system within 1–2 years. However, if the virus becomes persistent, it can lead to cellular changes. Regular testing is therefore important.

How Is the HPV Test Performed?

The HPV test is performed during a gynecological examination. A cell sample is taken from the cervix with the help of a small brush. The procedure generally takes 1–2 minutes and is painless for most women.

The collected sample is examined in the laboratory for high-risk HPV DNA.

What Does the HPV Test Show?

The HPV test shows the following:

• The presence of high-risk HPV types
• Infection carrying a cancer risk
• Conditions requiring follow-up

The HPV test detects the presence of the virus, not cellular changes. To evaluate cellular changes, a smear test is performed. In some situations, these two tests can be applied together.

Why Is the HPV Test of Critical Importance?

While the smear test detects cellular changes, the HPV test detects the main cause of these changes (the virus).

• Early Warning System: High-risk HPV infections generally begin years before any abnormality appears in the smear test. The HPV test catches the virus in this silent period, allowing the patient to be placed under closer follow-up.
• High Sensitivity: It has higher sensitivity than the smear test in determining cancer risk, which allows screening intervals to be extended.
• Typing: The test can also determine which type of HPV virus is present (especially Type 16 and 18, which carry a high cancer risk).

Which Diseases Does the HPV Test Indicate?

1. Cervical Cancer: Detection of high-risk HPV types (especially Type 16 and 18) in the HPV test indicates an increased risk of developing cervical cancer.

However, it is important to know this: being HPV positive does not directly mean that you have cancer.

The test determines the likelihood of cancer development at an early stage, allowing the necessary follow-up and precautions to be taken.

2. Precancerous Cellular Changes: If HPV infection remains in the body for a long time, it can cause abnormal changes in cervical cells. These changes may be:

• Low grade (low risk)
• High grade (precancerous)

When the HPV test is performed together with the smear test, these cellular changes can be evaluated more clearly. In this way, treatment can be planned before cancer develops.

3. High-Risk HPV Infection: There are more than 200 types of HPV. Some of them are low risk (leading to genital warts), while others are high risk and associated with cancer.

The HPV test specifically detects the following:

• High-risk HPV types
• The presence of persistent infection
• Long-term cancer risk

The immune system clears most HPV infections within 1–2 years. However, if the infection becomes persistent, regular follow-up is required.

How Is the HPV Test Applied? (Sample Collection and Laboratory Process)

The HPV test is performed by examining, in the laboratory, a cell sample taken from the cervix during a gynecological examination. The procedure is brief and generally painless.

Taking a Cell Sample from the Cervix:

• The patient lies in the gynecological examination position.
• A speculum is placed in the vagina to make the cervix visible.
• A cell sample is taken from the cervix with the help of a small brush.
• The procedure takes approximately 1–2 minutes.

Most women feel only a slight pressure. Mild spotting may rarely occur after the procedure.

Laboratory Process and Result Time: The collected cell sample is placed in special tubes and sent to the laboratory. In the laboratory:

• The presence of HPV DNA is investigated.
• High-risk HPV types (especially 16 and 18) are analyzed.

Results are generally available within 3–7 business days. In some centers, this period may extend to 1–2 weeks.

When Should the HPV Test Be Performed?

The HPV test is an important screening test performed for the early detection of high-risk HPV types. When the test should be performed depends on age, sex, and individual risk factors.

For Routine Screening:

• Screening is generally started between the ages of 25–30 (this may vary by country and guideline).
• The HPV DNA test is particularly recommended for women aged 30 and over.
• It can be performed together with the smear test or on its own.
• If results are normal, the test may not need to be repeated for up to 5 years.
• If three consecutive normal results have been obtained in regular follow-ups, subsequent screenings can be planned every 5 years.

If the Smear Result Is Abnormal:

• When a cellular change is detected
• The HPV test is performed to clarify the cause

If There Are HPV Symptoms or Suspicion:

• Presence of genital warts
• HPV detected in a partner
• After unprotected or risky sexual contact

In Those with a Weakened Immune System:

• Testing may be recommended at an earlier age
• And at more frequent intervals

Are the HPV Test and the Smear Test the Same?

No, the HPV test and the smear test are not the same, but they are two important screening methods that complement each other.

• HPV test: Investigates the presence of the high-risk HPV virus that can lead to cervical cancer. In other words, it detects the DNA of the virus.
• Smear test (Pap smear): Shows whether there are abnormal changes in cervical cells.

In summary: the HPV test shows the virus, while the smear test shows the cellular change.

In women aged 30 and over, the two tests are generally performed together (co-testing). This method helps evaluate cervical cancer risk in a more reliable way.

What Do HPV Test Results Mean?

The HPV test result shows whether virus types that could lead to cancer are present in the cervix. Results are generally evaluated as follows:

HPV Positive: An HPV positive result shows that the HPV virus is present in the body.

However, this does not directly mean that you have cancer.

Most HPV infections are cleared by the immune system within 1–2 years. However, high-risk types require regular follow-up.

High-Risk HPV: High-risk HPV types (especially types 16 and 18) are associated with cervical cancer.

When these types are detected:

• Cellular change is evaluated with a smear test.
• If necessary, further investigations such as colposcopy are performed.
• Regular follow-up is planned.

Thanks to early detection, intervention is possible before cancer develops.

Low-Risk HPV: Low-risk HPV types are generally not associated with cancer. They can more often lead to genital warts.

In this case, generally:

• The cancer risk is low.
• Clinical follow-up is sufficient.

Cellular Changes Such as ASC-US, LSIL, HSIL: These terms are usually obtained from the smear test result rather than the HPV test; however, they gain importance when evaluated together with HPV positivity:

• ASC-US: Undetermined, mild cellular change
• LSIL: Low-grade cellular change
• HSIL: High-grade change, considered precancerous

If HSIL is detected together with HPV positivity, a more detailed examination is required.

What Should Be Considered After the HPV Test?

After the HPV test, no special restrictions are generally required. The procedure is a simple sample collection, and daily life can be resumed immediately. However, the follow-up plan based on the results is important.

Follow-Up for Those with a Positive Result: An HPV positive result requires regular check-ups, especially when high-risk types are detected.

• Your doctor may use a smear test to evaluate whether there is a cellular change.
• If necessary, colposcopy may be recommended.
• Most HPV infections clear on their own within 1–2 years.

What matters is not to panic, but to adhere to the regular follow-up program.

Informing the Sexual Partner: HPV is a sexually transmitted virus. Therefore:

• Informing the partner is recommended.
• There is no routine HPV screening test for men, but an evaluation can be made if symptoms are present.
• Condom use reduces the risk of transmission but does not eliminate it completely.

HPV is a very common infection, and most people may encounter the virus at some point in their lives.

Time for Repeat Testing: The repeat testing interval depends on the result:

• If HPV negative, routine screening is generally recommended after 5 years.
• If HPV positive but the smear is normal, a repeat test can be planned after 1 year.
• If there is an abnormal cellular change, closer follow-up may be required.

The follow-up interval must be determined according to the doctor’s recommendation.

Can the HPV Test Be Done During Pregnancy?

Yes, the HPV test can be done during pregnancy and is generally safe.

Is It Safe?: The HPV test is performed by taking a superficial cell sample from the cervix. The procedure does not harm the baby and does not increase the risk of miscarriage.

Is There Any Risk?: In most cases there is no risk. Mild spotting may rarely occur.

If there has been an abnormal result previously, the follow-up plan during pregnancy is arranged specifically by the doctor.

Is the HPV Test Reliable?

The HPV test is a quite reliable screening method for determining the risk of cervical cancer.

Accuracy Rate: HPV DNA tests have high sensitivity and are strong in detecting high-risk HPV types. For this reason, they are recommended in addition to the smear test for women over 30.

Is There a Possibility of Error?: Although rare, a false negative or false positive result may occur for reasons such as:

• Insufficient sample collection
• Laboratory error
• Very early-stage infection

For this reason, it is important to have regular screening and to proceed under a doctor’s supervision.
