An overview of the Herpes Simplex Virus Type 1 and Type 2 urine Polymerase Chain Reaction test

The Herpes Simplex Virus Type 1 and Type 2 by Polymerase Chain Reaction (Urine) test is a molecular diagnostic test designed to detect viral DNA directly, rather than antibodies. This means it identifies current, active infection, not past exposure.

Unlike blood antibody tests, which measure the immune response, this urine-based Polymerase Chain Reaction test detects the presence of Herpes Simplex Virus genetic material itself. This makes it particularly useful during early infection, before antibodies have developed, or when symptoms are present but blood tests are inconclusive.

Because urine sampling is non-invasive and convenient, this test is often preferred when genital symptoms are present, when lesions are internal, or when swab testing is not feasible.

Clinical reasons for testing for Herpes Simplex Virus Type 1 and Type 2 using urine

This test is appropriate if you want to confirm whether active viral shedding is occurring. It is especially valuable when symptoms are recent, atypical, or when antibody tests may not yet be reliable.

Herpes Simplex Virus infections do not always cause visible sores. In some individuals, symptoms may be internal, mild, or mistaken for urinary or genital irritation. Molecular testing provides clarity by identifying the virus directly, rather than relying on immune response timing.

Testing may be appropriate if you experience:

• Genital discomfort without visible sores
• Pain or burning during urination
• Recent genital ulcers that have healed
• Unexplained genital irritation or discharge
• Recent sexual contact with a diagnosed partner
• Early symptoms before antibodies are expected to appear
• Unclear or conflicting blood test results

Advantages of the urine Polymerase Chain Reaction test

·      Direct detection of active infection
Identifies viral DNA rather than immune response.

·      Highly sensitive diagnostic method
Capable of detecting low levels of virus.

·      Effective during early infection
Useful before antibodies have developed.

·      Non-invasive sample collection
Simple urine sample, no blood draw required.

·      Useful when lesions cannot be swabbed
Ideal if sores are internal or healed.

·      Clear differentiation between active and past infection
Confirms current viral presence only.

·      Supports timely clinical decisions
Enables appropriate guidance and follow-up.

·      Discreet and convenient testing option
Suitable for patients seeking privacy and comfort.

How the test is carried out

We provide two UK-wide testing options:

Clinic-based urine testing

• Choose your nearest UK clinic
• Provide a urine sample during your appointment
• Sample is sent to the laboratory for molecular analysis
• Results are issued once testing is complete

Home or hotel sample collection (+£60)

• A healthcare professional attends your location
• Clear instructions are provided for urine collection
• No travel or clinic visit required
• Available nationwide across the UK

Both options use the same laboratory methodology and quality standards.

Understanding your Herpes Simplex Virus Type 1 and Type 2 urine results

Virus not detected

No Herpes Simplex Virus Type 1 or Type 2 genetic material was identified in the urine sample. This suggests no active viral shedding at the time of testing.

Laboratory reporting standard:

• Not detected

If symptoms persist, repeat testing or alternative testing methods may be recommended.

Indeterminate result

An indeterminate result means that viral material was detected at a very low level or the sample quality was insufficient for a definitive conclusion.

Laboratory reporting standard:

• Indeterminate

Repeat testing is usually advised to confirm status.

Virus detected

Viral genetic material from Herpes Simplex Virus Type 1 or Type 2 has been identified, indicating active infection or viral shedding at the time of testing.

Laboratory reporting standard:

• Detected

Clinical correlation and further advice may be recommended depending on symptoms and history.
