HPV Test
Screening for HPV is an integral part of the annual preventive gynecological exam. Since the virus does not cause symptoms in most cases, early detection through specialized tests is the only reliable way to protect against the complications it can cause.
What is the HPV virus?
HPV (Human Papillomavirus) is the human papillomavirus and is currently the most common sexually transmitted infection worldwide. It is so widespread that it is estimated that every sexually active person has up to an 80% chance of becoming infected with some type of the virus at some point in their life.
The virus infects the skin and mucous membranes of the genital organs, the oral cavity, and the pharynx. In most cases, it causes no symptoms, and the immune system clears it on its own within 1 to 2 years. Only when the virus remains in the cells of the cervix for a longer period of time is there a risk of lesions developing.
The virus is transmitted primarily through sexual contact, and in most cases, the infected person is unaware that they carry it or that they are transmitting it to their partner.
Symptoms - Why Regular Checkups Are Essential
One of the most distinctive features of HPV is that in the vast majority of cases, it causes no symptoms. This means that a woman may carry the virus for years without knowing it and without experiencing any discomfort that would prompt her to see a gynecologist.
This is why HPV is often called a “silent virus” and why regular preventive screening is the only reliable way to detect it. The same applies to the precancerous lesions that the virus can cause on the cervix. These, too, develop without pain or other obvious symptoms and are detected exclusively through preventive gynecological screening.
The absence of symptoms does not rule out infection. Annual gynecological checkups remain the only reliable form of protection.
HPV Strains - High-Risk and Low-Risk
HPV comprises more than 100 different types, which are classified into two broad categories based on their carcinogenic risk:
Low-Risk Types
Low-risk types (mainly HPV 6 and HPV 11) cause benign lesions and are not associated with cancer. In most cases, the immune system effectively fights them off.
High-Risk Types
High-risk types (primarily HPV 16 and HPV 18, but also types 31, 33, 45, 52, and 58) are those that, under certain conditions, can cause precancerous lesions and cervical cancer. The lesions they cause are not visible during a routine clinical examination and can only be detected through specialized tests.
How often does HPV lead to cancer?
The presence of high-risk HPV does not automatically mean cancer. In young women, the infection is cleared by the immune system in up to 90% of cases within 2 to 3 years. Only in the percentage of women in whom the virus remains active for a longer period of time is there an increased risk of developing precancerous lesions. If detected early, these lesions are, in most cases, fully treatable.
How the Inspection Is Conducted
HPV screening involves three basic tests that are often combined to provide a more comprehensive diagnostic picture:
Pap Test
The Pap test examines cells from the cervix and can detect cellular changes caused by HPV. It does not directly detect the virus itself, but rather its cytological effects.
An abnormal Pap test result is usually the reason for further specialized HPV testing.
HPV DNA Test
The HPV DNA Test directly detects the virus’s genetic material in cervical cells, even when the Pap test appears normal. Using the PCR method, the exact type of virus is identified, distinguishing high-risk from low-risk strains.
It is currently the most reliable tool for the early detection of HPV.
Colposcopy
If any of the above tests yield a suspicious result, the gynecologist recommends a colposcopy. This method involves a detailed examination of the cervix using a special colposcope, and if suspicious lesions are identified, biopsies are taken for a definitive histological diagnosis.
Important: It is recommended that the HPV DNA Test and the Pap Test be performed simultaneously (co-testing), as their combination offers significantly higher diagnostic accuracy than either test alone.
What Does a Positive HPV Test Result Mean?
A positive result on an HPV test often causes concern. However, it is important to clearly understand what a positive result does and does not mean clinically.
A positive result does not mean that cancer is present, nor does it mean that progression to cancer is inevitable. It means that the virus was detected in the cells of the cervix, which happens to a significant percentage of women at some point in their lives. The next diagnostic step depends on the type of virus detected. In the case of a low-risk strain, more frequent monitoring is usually recommended, while the detection of a high-risk strain such as HPV 16 or HPV 18 leads to a recommendation for colposcopy to assess any cervical lesions.
HPV and Pregnancy
An HPV diagnosis does not imply difficulty conceiving or complications during pregnancy. If therapeutic intervention on the cervix is deemed necessary, the gynecologist takes the patient’s reproductive wishes into account before making any decision.
Cervical cancer is a rare consequence of HPV infection and, in most cases, is completely preventable through regular screening.
Frequently Asked Questions (FAQ)
Yes, and this is the case in the vast majority of situations. The immune system usually clears the virus within 1 to 2 years. In young women, the rate of spontaneous clearance of the infection reaches up to 90%. A positive result does not automatically mean treatment is necessary—but it does require follow-up by a specialist gynecologist.
The detection of high-risk strains such as HPV 16 or HPV 18 necessitates closer monitoring. Cervical cancer develops slowly, usually over many years, and is always preceded by precancerous lesions that can be detected and treated early with appropriate monitoring.
Condoms significantly reduce the risk of transmission but do not provide complete protection, as the virus may be present in areas not covered by the condom. For this reason, regular preventive testing remains essential regardless of condom use.
The detection of HPV traces in a Pap test is a common clinical finding. The gynecologist will evaluate the result and will likely recommend an HPV DNA test to determine the type of virus and, if deemed necessary, a colposcopy for a more detailed assessment of the cervix. The finding should not be ignored; however, it does not automatically indicate a serious condition.
An HPV infection in itself does not affect fertility and does not prevent pregnancy. If cervical lesions requiring treatment are detected, the gynecologist develops an appropriate treatment plan, always taking the patient’s reproductive wishes into account.
