Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like redness, pain, or discharge in your eye, especially if you suspect a viral infection. It’s particularly useful for diagnosing conditions like herpes keratitis, a type of eye infection caused by HSV affecting the cornea.

What Does the Test Involve?

A small sample of your corneal tissue is collected using a sterile swab or scraping tool. This sample is then sent to a lab for culture, where it’s grown in a controlled environment to identify HSV if present.

How Is the Test Performed?

The procedure is quick and typically done in a doctor’s office or clinic. You may feel slight discomfort or pressure, but it’s not painful. Local anesthesia might be applied to numb the area before sampling.

What Are the Results?

Results are usually available within 3–14 days. A positive culture confirms HSV infection, while a negative result means no HSV was detected in the sample. Follow-up testing or treatment may be recommended based on the results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What Does It Mean If I Have HSV in My Eye?
If HSV is confirmed, treatment with antiviral medications may be prescribed to reduce symptoms, prevent complications, and shorten the infection duration. Untreated HSV eye infections can lead to scarring, vision loss, or recurring infections.
What If My Test Is Negative?
A negative result means HSV wasn’t detected in the sample, but other causes of your eye symptoms (like bacterial infections or allergies) could still be responsible. Your doctor may recommend further testing or different treatments.
How Can I Reduce the Risk of HSV Eye Infections?
If you’ve had HSV before, practice good eye hygiene (avoid touching your eyes, wash hands frequently), and use protective eyewear if exposed to irritants. If you experience eye redness or discomfort, seek medical attention promptly.
