Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms such as a sore throat, mouth ulcers, or fever that could be caused by HSV-1. It’s also used to confirm a diagnosis in certain cases, such as after exposure to someone with an active infection.

What to Expect Before the Test

No special preparation is needed. You may rinse your mouth with water before the test to cleanse your throat. Bring any medications you’re currently taking, as this may affect results.

How the Test Is Performed

A healthcare provider will swab the back of your throat using a sterile cotton-tipped applicator. The swab will be placed in a special container for lab analysis. The sample is then sent to a lab for culturing to grow HSV-1 if present.

What the Test Results Mean

A positive result means HSV-1 was detected in your throat sample. A negative result means the virus was not found in this sample. Results may take several days to a week to receive, depending on lab processes.

Clinical interpretation

Frequently asked questions

What Does This Test Detect?
This test detects the presence of HSV-1 in your throat by growing the virus in a lab setting. It helps confirm a diagnosis of primary or recurrent HSV-1 infection, especially if symptoms like sore throat, ulcers, or fever are present.
What Are Common Symptoms?
Common symptoms of HSV-1 throat infection may include sore throat, pain when swallowing, fever, swollen lymph nodes, and sometimes mouth ulcers. These symptoms can vary widely and may mimic other conditions.
How Is This Test Different From Other Tests?
Unlike blood tests that measure viral markers (such as antibodies), this culture directly identifies live HSV-1 in your throat sample. It’s particularly useful for diagnosing active infections rather than past exposure.
