The herpes PCR (polymerase chain reaction) test is a diagnostic tool used to detect the genetic material of the herpes simplex virus (HSV) in a patient's sample, typically from genital sores, oral lesions, or other affected areas. PCR is a sensitive and specific method that amplifies and analyses the DNA to identify the presence of the virus.

This test is particularly useful for confirming a herpes infection, determining the type of herpes (HSV-1 or HSV-2), and differentiating it from other skin conditions. It is especially valuable in cases where symptoms are present, and a more precise diagnosis is needed.

Your clinician will suggest a herpes PCR test to diagnose or rule out, or confirm, the possibility of a herpes infection.

The herpes PCR test directly identifies the genetic material (DNA) of the herpes simplex virus in a sample taken from a sore or lesion. This test is particularly valuable for confirming an active herpes infection, specifying the type (HSV-1 or HSV-2), and distinguishing it from other skin conditions. Unlike antibody tests, PCR can provide more immediate confirmation during an active infection.

On the other hand, the herpes antibody test (IgG/IgM) focusses on detecting antibodies produced by the immune system in response to a herpes infection. IgG signifies a past infection, while IgM indicates a recent one. These tests help determine past exposure and provide insights into the timing of the infection, with IgG developing later and IgM appearing in the early stages.

There is no window period for the herpes PCR test. However, the chances of detecting the herpes virus are higher when the lesions are active. Once the lesions have scabbed and dried up, there may not be any virus in the sample to detect. Therefore, the best time to test will be to obtain the swab as soon as the lesion appears.

The herpes PCR test is performed when symptoms suggestive of Herpes are present. Other reasons include:

• Confirming a herpes diagnosis as well as the typing of the virus (HSV-1/2)
• Ruling out a herpes diagnosis from a lesions and distinguishing from other skin conditions, such as thrush, trauma, or eczema.

An examination will be offered if you are experiencing symptoms. This allows the clinician to assess the extent of your symptoms, take the herpes sample, and ensure no secondary complications are present.

Although an examination may be recommended, this is entirely your decision. Your clinician will explain everything clearly.

Yes.

Everything you share with us is confidential and will not be shared with the NHS or any other healthcare provider, including your GP unless you specifically ask us to do so.

You can receive your Herpes PCR test results by either text or email.

It is essential that you avoid any type of sex whilst waiting for your results. Your clinician will advise you on any extra precautions depending on your situation, your symptoms, and if you are taking treatment.

After confirming a positive herpes diagnosis, we will discuss what it means for you and provide effective medication to manage the condition and lower the chances of passing it to your partner.

If you follow the instructions given to you by your clinician, you can expect to live normally after a herpes outbreak. This includes starting new relationships, having a successful pregnancy, and thinking about a regular vaginal delivery (for female patients).

It is not required by law to disclose this information to your sexual partners. However, if you decide to do so, consider the following tips:

• Choose an appropriate time and place for the conversation, ensuring privacy and comfort.
• Be calm and respectful in your approach.
• Emphasise that you are sharing this information because you care about their health.
• Be prepared to answer any questions your partner may have about herpes, its transmission, and how you plan to manage it.
• Encourage your partner to get tested for sexually transmitted infections (STIs), including herpes, themselves. Testing can provide them with their own status and information.

Reactions to such disclosures can vary, and some partners may have concerns or questions. Being patient, understanding, and empathetic during these conversations is essential.

If you have concerns about how to approach this conversation or need guidance on managing herpes in a relationship, speak to your clinician who can offer support and information to help you and your partner(s) navigate this important discussion.

Yes.

Along with a text or email of your Herpes PCR test results, we can email a certificate for official purposes.
