Genital warts are diagnosed through a visual exam by a healthcare provider, not a lab test you can order online or do at home. You can get checked at a primary care office, a sexual health clinic, an OB-GYN, a dermatologist, or a urologist. Most visits take only a few minutes, and a provider can usually tell you on the spot whether what you’re seeing is a genital wart.
Where You Can Go
Several types of clinics and providers can diagnose genital warts. Your best option depends on your insurance, budget, and how quickly you want to be seen.
- Primary care doctor. Your regular doctor can diagnose genital warts during a standard office visit. This is often the fastest route if you already have a provider.
- Sexual health or STI clinics. Publicly funded clinics (like those run by local health departments or Planned Parenthood) specialize in STI screening and treatment. Many offer sliding-scale fees or free visits, and they’re set up to handle these exams efficiently and confidentially.
- OB-GYN. For women, a gynecologist can diagnose warts during a routine pelvic exam or a dedicated visit. This is especially important if warts appear on or near the cervix.
- Urologist. Men with warts in harder-to-see areas, like inside the urethra, may be referred to a urologist for a closer look.
- Dermatologist. A skin specialist can help when the appearance of a bump is unusual or when growths haven’t responded to initial treatment.
- Urgent care. Some urgent care centers can do a visual assessment, though they may refer you elsewhere for treatment or biopsy.
There Is No Blood Test or At-Home Test for Genital Warts
This is one of the most common points of confusion. HPV tests do exist, but they screen for the high-risk strains of HPV linked to cancer, not the low-risk strains that cause visible warts. The CDC explicitly states that HPV tests should not be used for diagnosing genital warts or as a general STI screening tool. There is no blood test, urine test, or swab that detects the wart-causing strains of HPV.
At-home HPV self-collection kits have recently gained FDA approval, but these are designed for cervical cancer screening in women. They detect high-risk HPV types and have nothing to do with genital wart diagnosis. If you have a bump you’re worried about, you need someone to look at it in person.
What Happens During the Exam
Diagnosis is almost always visual. A provider will examine the area in good lighting and can typically identify genital warts by their appearance: small, flesh-colored or grayish bumps that may be flat, raised, or have a cauliflower-like texture. The whole process often takes just a few minutes.
In some cases, providers use an acetic acid (vinegar) test. They apply a dilute vinegar solution to the skin for three to five minutes, which turns wart tissue white and makes it easier to see. This technique works well for raised, fleshy warts but is less reliable for flat or subtle lesions, and it doesn’t reliably detect areas of subclinical HPV infection that aren’t yet visible.
A biopsy, where a small piece of tissue is removed and sent to a lab, is not routine. It’s reserved for situations where the bump looks unusual (pigmented, bleeding, ulcerated, or firmly attached to deeper tissue), when standard treatment isn’t working, or when a provider needs to rule out precancerous changes. Women with warts on the cervix will typically have a biopsy before treatment begins to check for more serious cell changes.
How Long Results Take
If your provider diagnoses warts visually, you’ll know during the appointment itself. No waiting required.
If a biopsy is needed, routine tissue samples often come back within one to two days of reaching the lab. Results can take longer if special staining techniques are required or if a pathologist requests a second opinion on an ambiguous sample. In those cases, expect results within one to three weeks. Your provider’s office should give you a specific timeframe when the sample is taken.
Cost and Confidentiality
With insurance, a genital wart exam is typically covered as a standard office visit. Without insurance, public sexual health clinics are your most affordable option. Many city and county health departments offer free or low-cost STI services regardless of your ability to pay. Planned Parenthood locations also use income-based sliding scales.
If you’re a minor, most states allow you to consent to STI testing and treatment without parental involvement. About half of U.S. states have explicit confidentiality protections that prevent disclosure to a parent or guardian. However, insurance billing can sometimes reveal visits through explanation-of-benefits statements sent to the policyholder. If privacy is a concern, paying out of pocket at a public clinic avoids creating an insurance record entirely.
How to Prepare for Your Visit
No special preparation is needed. You don’t need to shave, avoid certain products, or time the visit around your menstrual cycle. Just show up as you normally are. If you’ve been applying any over-the-counter creams or treatments to the area, mention that to your provider since some products can temporarily change the appearance of the skin.
It helps to note when you first noticed the bump, whether it has changed in size or number, and whether you have any symptoms like itching. If you’ve had genital warts before or have been treated for HPV-related issues in the past, share that history. This information helps your provider decide whether a visual diagnosis is sufficient or whether further evaluation is warranted.
