Herpes simplex virus (HSV) is one of the most common viral infections worldwide. It is caused by two closely related viruses – HSV-1 and HSV-2 – that can affect the mouth, lips, and genital areas. Oral herpes typically appears as painful blisters or sores around the mouth, sometimes known as “cold sores.”
The Herpes Simplex (HSV) 1 & 2 by PCR – Oral Lesion Test is a highly accurate way to confirm whether an oral sore is caused by HSV-1 or HSV-2. Unlike antibody blood tests, this PCR test directly detects the virus from a swab taken from an active lesion, giving you quick and reliable answers.
With our at-home kit and UKAS-accredited laboratory analysis, you can get clarity fast, without needing to attend a clinic.
Most commonly causes oral herpes, leading to cold sores around the mouth or lips.
Can also be transmitted to the genital area through oral sex.
More commonly linked to genital herpes.
Can occasionally cause oral infections through intimate contact.
Both HSV-1 and HSV-2 are highly contagious, especially when sores are visible, but transmission can also occur without symptoms.
Testing is important because:
Many other conditions can mimic herpes sores.
Early confirmation helps with treatment decisions.
Knowing your HSV type helps manage outbreaks and reduce transmission risk.
There are several ways to test for HSV, but PCR (polymerase chain reaction) is the most accurate.
Direct detection – Identifies the virus’s DNA, not just antibodies.
Highly sensitive – Can detect very small amounts of virus.
Fast results – Typically available in 1–2 working days.
Type-specific – Distinguishes between HSV-1 and HSV-2.
This makes PCR the gold standard for diagnosing herpes infections, particularly when sores are present.
You may consider this test if you:
Have painful blisters, ulcers, or sores around your mouth or lips.
Experience tingling, burning, or itching sensations before sores appear.
Want to confirm if recurrent “cold sores” are due to HSV.
Have had oral contact with someone known to carry herpes.
Need clear results for peace of mind, medical treatment, or partner disclosure.
Tingling or burning before sores develop
Painful blisters or ulcers on or around the lips
Redness and swelling
Sore throat or swollen lymph nodes (in primary infections)
Flu-like symptoms in some cases
Because these symptoms can overlap with other conditions (such as canker sores, bacterial infections, or allergic reactions), testing is the only way to confirm herpes.

1. Can I take this test if I don’t have an active sore?
No. This PCR test requires a swab from a visible lesion. If you have no sores, an HSV antibody blood test may be more appropriate.
2. Is herpes curable?
No, herpes is a lifelong viral infection. However, antiviral medication can reduce symptoms, shorten outbreaks, and lower transmission risk.
3. How long after a sore appears should I test?
Ideally, swab the lesion within the first few days of appearance for the highest chance of detecting the virus.
4. Will a positive result affect my relationships?
Not necessarily. Many people live with HSV and manage it successfully. Knowing your status helps you take steps to reduce transmission.
5. Can I spread herpes without symptoms?
Yes. HSV can be shed even when sores aren’t visible, though it is most contagious during outbreaks.
