Herpes Simplex Virus (HSV) Type 1&2, PCR, Qualitative

HERPES SIMPLEX VIRUS (HSV) TYPE 1&2, PCR, QUALITATIVE Test

The Herpes Simplex Virus (HSV) Type 1 & 2, PCR, Qualitative test detects the genetic material (DNA) of Herpes Simplex Virus Type 1 (HSV-1) and Type 2 (HSV-2) in a clinical specimen.

PCR is a highly sensitive molecular method that can help identify HSV infection when symptoms such as painful blisters, sores, ulcers, or lesions are present. Depending on the clinical situation, the sample may be collected from a lesion, genital area, oral area, or other relevant site.

The test can distinguish between HSV-1 and HSV-2 when the laboratory assay is designed for type-specific detection. A positive result indicates that HSV DNA was detected in the tested specimen. A negative result means HSV DNA was not detected in that particular sample, although the result should be interpreted based on symptoms, specimen quality, and timing of collection.

Test Recommended for Individuals:

• Individuals with genital or oral sores suspected to be caused by HSV
• People with painful blisters, ulcers, or lesions in the genital or oral region
• Individuals with suspected genital herpes
• People with recurrent or unexplained mucocutaneous lesions
• Patients requiring differentiation between HSV-1 and HSV-2 infection
• Individuals with suspected HSV infection when direct molecular testing is clinically indicated
• Patients advised by their healthcare provider to undergo HSV PCR testing

FAQs

1. What does the HSV Type 1 & 2 PCR test detect?
The test detects HSV-1 and HSV-2 DNA in the collected specimen. It can help confirm whether herpes simplex virus is present at the tested site.

2. What is the difference between HSV PCR and HSV antibody testing?
HSV PCR looks for the virus's genetic material directly in a specimen, making it useful when an active lesion or infection is suspected. Antibody tests measure the body's immune response and are generally used to assess previous exposure.

3. What does a negative HSV PCR result mean?
A negative result means that HSV DNA was not detected in the tested specimen. However, a negative result does not always completely exclude infection, particularly if the sample was collected late, the lesion was healing, or the specimen did not contain enough viral material. Your healthcare provider will interpret the result along with your symptoms and examination findings.
