Are false positive HPV tests common?

It's up to 30 percent of people [who] are falsely positive." These false positive cases can lead to unnecessary, higher risk follow-up procedures, like biopsies.

Can Pap smear false-positive HPV?

That's why false-positive results occur occasionally in Pap smears, but they're extremely rare in HPV tests. To ensure accurate results, the American College of Obstetricians and Gynecologists says to avoid douching, intercourse and any vaginal medications for two days before your screening.

Should I worry if my HPV test is positive?

A positive test result doesn't mean a cancer diagnosis is inevitable—it simply means you're at a higher risk. We take positive HPV results and cellular abnormalities very seriously and conduct extensive testing and regular monitoring to make sure the virus doesn't result in more serious issues.

How accurate is a HPV test?

The absolute accuracy varied by clinical setting. In the context of screening, HPV testing on self-samples detected, on average, 76% (95% CI 69-82) of CIN2 or worse and 84% (72-92) of CIN3 or worse. The pooled absolute specificity to exclude CIN2 or worse was 86% (83-89) and 87% (84-90) to exclude CIN3 or worse.

How common is a false-positive abnormal pap?

It's up to 30 percent of people [who] are falsely positive." Women who have a positive Pap smear generally get a colposcopy, which is an even closer examination of the cervix, vagina and vulva for signs of disease. A false positive could mean going through a biopsy during a colposcopy.

What would cause a false positive HPV test?

Sometimes these false positive Paps can be explained by a recent vaginal infection, or trauma to the cervix due to douching, tampons, or intercourse; sometimes the false positives just represent an inherent limitation of the test.

Can colposcopy results be wrong?

About 6 in 10 colposcopy results are abnormal. This means the tests done during colposcopy or biopsy have confirmed you have cell changes. Possible abnormal results include: cervical intraepithelial neoplasia (CIN)

Do I need a colposcopy if I have HPV?

If you test positive for HPV 16/18, you will need to have a colposcopy. If you test positive for HPV (but did not have genotyping performed or had genotyping and tested negative for 16/18), you will likely have a colposcopy.

How sensitive is HPV test?

The estimated sensitivity of HPV DNA testing was higher than that of conventional Pap smear (68.1% vs 40.2%). The estimated specificity of Pap testing was 91.6% compared with 90.6% for HPV DNA testing.

Can you test positive for HPV then negative then positive again?

An HPV test will come back as a positive test result or a negative test result: Negative HPV test result: High-risk HPV was not found. You should have the test again in 5 years. You may need to come back sooner if you had abnormal results in the past.

How often are colposcopy results normal?

Colposcopy results

About 4 out of 10 women who have a colposcopy have a normal result. A normal result means your cervix appears healthy and you have a low risk of developing cervical cancer before your next screening test.

What should I do if I test positive for HPV?

If you got a positive HPV test and your Pap test was abnormal, your doctor will probably follow up with a colposcopy. Try to see a physician who specializes in this procedure. During a colposcopy, your doctor will look more closely at the cervix, vagina or vulva with a special microscope called a colposcope.

How accurate are colposcopy?

In the literature, the reported accuracy of colposcopy-directed biopsy is in the range of 60–95% for HSIL and 26–31% for invasive carcinoma [22,23,24,25]. This has raised concerns about the possibility that HSIL lesions may be missed, leading to invasive cervical cancer.

Can a yeast infection cause a positive HPV test?

In some cases , a yeast infection may not cause any symptoms, so a person may not know they have it. In this case, the Pap smear result may come back as ASC-US. If this happens, the NCI states that the doctor may perform an HPV test if they did not do this previously to determine if the abnormal result is due to HPV.

What does a normal Pap but positive HPV mean?

A positive HPV test means you do have an HPV type that may be linked to cervical cancer. This does not mean you have cervical cancer now. But it could be a warning. The specific HPV type may be identified to determine the next step.

How often should I get a Pap smear if I have HPV?

every 5 years with high-risk HPV testing alone. every 5 years with Pap and high-risk HPV cotesting. every 3 years with a Pap test alone.

How long does it take for HPV to show up after exposure?

A: The median time for HPV infection to grow into a genital wart is 3-6 months. This is called the incubation period. The incubation period ranges from 1-8 months but in some cases growth can be detected as early as 2 weeks after contact while in other cases growths are not detected until over a year after contact.

How long does it take for HPV to cause abnormal cells?

HPV-related cancers often take years to develop after getting an HPV infection. Cervical cancer usually develops over 10 or more years. There can be a long interval between being infected with HPV, the development of abnormal cells on the cervix and the development of cervical cancer.

Can you clear HPV after 30?

There is no cure for HPV, but 70% to 90% of infections are cleared by the immune system and become undetectable. HPV peaks in young women around age of sexual debut and declines in the late 20s and 30s. But women's risk for HPV is not over yet: There is sometimes a second peak around the age of menopause.

Can you have a positive HPV test and a normal Pap?

Some women for whom we test for HPV will have a normal pap smear, but have a positive high risk HPV result. This is particularly confusing because they may have never had an abnormal pap smear, and they may never even develop one.

Can HPV go away after 5 years?

Depending on the type of HPV that you have, the virus can linger in your body for years. In most cases, your body can produce antibodies against the virus and clear the virus within one to two years. Most strains of HPV go away permanently without treatment.

What can cause an abnormal Pap smears besides HPV?

Most abnormal Pap tests are caused by HPV infections. Other types of infection—such as those caused by bacteria, yeast, or protozoa (Trichomonas)—sometimes lead to minor changes on a Pap test called atypical squamous cells.

Is CGIN worse than CIN?

CGIN is usually classified as low grade (mild) or high grade (severe). High grade CGIN is the equivalent of CIN3. CGIN can be multi-focal – this means that more than one area is affected at one time, with normal tissue lying between them.

Why do I need a second colposcopy?

If cell changes come back, they are usually found after your follow-up appointment. If your cervical screening (smear test) done during this appointment finds high-risk HPV, you will usually have further tests at colposcopy again.

Can Pap smears be wrong?

A Pap smear is a safe way to screen for cervical cancer. However, a Pap smear isn't foolproof. It's possible to receive false-negative results — meaning that the test indicates no abnormality, even though you do have abnormal cells. A false-negative result doesn't mean that a mistake was made.
