The herpes viral culture of lesion test, also known as the herpes simplex virus culture, is a laboratory test that’s used to determine if a skin sore contains the herpes simplex virus (HSV).
In this article, we’ll cover how the test works, why it’s given, and more.
HSV infections are
HSV-1 is the main cause of conditions like cold sores and fever blisters. This virus

Once a person is infected with HSV, there’s no cure. Outbreaks of HSV may occur frequently or only once in a person’s life.
Skin or genital sores that’ve been infected with HSV are often diagnosed in a clinical setting through a physical exam.
Even though your doctor can often identify and diagnose a herpes skin lesion without laboratory testing, there are cases when diagnosis may be difficult to confirm. When this occurs, your doctor may order a herpes viral culture lesion test.
There are situations in which the virus poses a significant
If you have health complications, like a compromised immune system, the detection of HSV is vital. Since HSV can be life-threatening in these conditions, a correct diagnosis is needed to ensure that treatment is provided in a timely manner.
To perform a
The test is typically performed in a clinical setting by a qualified healthcare professional. They’ll need to scrape the sore to collect fluid and cells from the skin.
You may experience some discomfort during the procedure. For skin lesions, you may feel a scraping sensation. If your lesion is located in your throat or eye, a sterilized swab must be used for sample collection. This may result in some discomfort.
Your sample will be placed in a laboratory container and taken to a lab for analysis. At the lab, the sample is placed in a dish and observed for 16 hours or up to 7 days to monitor the growth of the virus. Results from the test are typically reported to your doctor within 2 to 5 days.
The risks of the herpes viral culture of lesion test are minimal. These risks are associated with any type of procedure that requires scraping of the skin and
- bleeding at the site where the sample was removed
- infection at the site where the sample was removed
- pain or discomfort at the sample site
If the virus doesn’t grow, then your results are negative. This means that you don’t have an active herpes infection at the site where the culture was taken. But a negative culture doesn’t mean that you don’t have herpes.
Growth of the virus from the collected sample indicates that your sore is infected with the herpes virus. Based on these findings, your doctor will prescribe a treatment for the infection.
