How to test for herpes
If you think you may have been exposed to herpes or are experiencing symptoms, testing is the best way to understand your status.
Healthcare providers typically diagnose herpes by examining visible sores and, if needed, confirming with lab testing. Common testing methods include:
- Swab test: A sample is taken from a sore and analyzed in a lab
- Blood test: Detects antibodies to determine if you’ve been infected
- Clinical evaluation: A provider examines symptoms and affected areas
Test results are usually available within a few days to a week, depending on the method and lab.
The CDC recommends herpes testing if you have symptoms or a partner with herpes [3]. Some people may have asymptomatic herpes, but routine screening without symptoms is not generally recommended [3].
If you want to check for other common STIs, Everlywell offers convenient at-home options. You can test for chlamydia, gonorrhea, hepatitis C, HIV, syphilis, and trichomoniasis with STD testing for women or STD testing for men, with results delivered securely online.
When to get tested
If you’ve been exposed to herpes or are experiencing symptoms such as blisters, sores, itching, or a burning sensation around the mouth or genital area, it may be time to get tested.
Keep in mind that herpes has an incubation period of about 2 to 12 days. Waiting at least 12 days after a potential exposure can help improve test accuracy.
Understanding herpes
Herpes is a common viral infection caused by one of two herpes simplex viruses [1]: herpes simplex virus type 1 (HSV-1) or herpes simplex virus type 2 (HSV-2).
HSV-1 most often causes cold sores around the mouth (oral herpes), while HSV-2 more commonly affects the genital area (genital herpes). Like gonorrhea and chlamydia, genital herpes can spread through close personal contact, including sexual activity.
There are many different types of STDs (or STIs), and understanding how they spread can help you better protect your health.
Signs and symptoms
Herpes symptoms can vary depending on the type of virus and whether it’s an initial or recurring outbreak. Some people may not experience symptoms at all.
Oral herpes is caused by HSV-1 [2] and typically affects the mouth and surrounding areas. (Related: STDs in women)
- Cold sores or fever blisters around the lips or mouth
- Flu-like symptoms during the first outbreak
- Swollen lymph nodes and headaches
- Redness, itching, or swelling before sores appear
- Blisters that break open, scab, and heal over time
The virus can remain dormant and reactivate periodically. Initial outbreaks are typically more severe, while recurring episodes tend to be milder.
Genital herpes is most commonly caused by HSV-2 and affects the genital area [1]. Symptoms can range from mild to more noticeable.
- Itching, burning, or irritation in the genital area
- Blisters or sores that may open and scab over
- Pain during urination
- Flu-like symptoms such as fever or muscle aches
Genital herpes spreads through sexual contact and is highly contagious, especially during active outbreaks. The virus can become inactive and later reactivate. Suppressive antiviral therapy may help reduce the frequency and severity of outbreaks.
Next Steps
If you think you may have a herpes infection, testing is an important next step.
Getting tested can help you better understand your status and take steps to protect your health and your partners. While some people may not experience symptoms, herpes can still be transmitted, making awareness and early action important.
If you’re experiencing symptoms or want to explore treatment options, you can connect with a licensed provider online and discuss next steps based on your needs.
