At-Home Herpes Test Kit

No. This kit relies on swabbing the surface of an active sore, blister, or ulcer to pick up viral material. If there is no sore present, there is nothing for the swab to detect, and the result will be negative regardless of whether you have herpes. If you want to investigate possible past herpes infection without a current sore, type-specific blood testing through a GP is a different test that can be discussed at an in-person or telehealth consult.

HSV-1 and HSV-2 are two related but distinct viruses. HSV-1 is the type more commonly causing cold sores around the mouth, although it can also cause genital herpes. HSV-2 more commonly causes genital herpes. Knowing the type matters because HSV-1 in the genital area is associated with a lower recurrence rate than HSV-2. The lab test included in this kit identifies the type, so the result tells you which virus was detected.

Crusted-over sores release much less viral material than fresh blisters or ulcers, so the swab is significantly less likely to pick up a result. If your sore has fully crusted and started healing, the kit may not give a useful answer. A negative result on a crusted sore does not rule out herpes. The kit is suited to use within the first few days of a sore appearing, while it is still moist or has fluid in it.

An in-person consult is usually the better choice for a first-ever genital sore. A first outbreak benefits from clinical examination to confirm the diagnosis, type-specific blood testing alongside the swab, and discussion of treatment options that ideally start within the first few days of symptoms. The at-home kit is suited to recurring outbreaks where the diagnosis is already familiar, or to confirming a suspected herpes lesion in someone who knows the territory.

Yes. The swab works on cold sores or any other suspected herpes lesion regardless of location. The technique is the same: press the swab firmly against the base of the sore for 5 to 10 seconds, rolling it back and forth to pick up cells. The lab test will identify whether HSV-1 or HSV-2 is present, which can be useful information even for a cold sore that you assume is HSV-1.

Most results are available within 2-3 days of the lab receiving the sample. Postal transit time depends on your postcode and the post day — allow one to three business days for the kit to reach the lab. Your result is sent by SMS as soon as it is available. If the result is positive, a Specialist GP calls you to discuss the result and any next steps.

Self-collected swabs of herpes lesions have lower sensitivity than clinician-collected swabs — mainly because of swabbing technique. A negative result does not reliably rule out herpes when there has been a typical-looking sore. If you remain concerned, options include re-testing during the next outbreak, type-specific blood testing through a GP, or in-person clinical assessment. The Specialist GP can discuss what makes sense in your situation.

It depends on your situation and partner status. Many people with herpes have had the virus for years without knowing. A current partner who has never had an outbreak may already have the virus and not know, or may not have it. Testing options for partners include type-specific blood testing or swabbing if and when they have a sore. The Specialist GP discusses partner testing and disclosure at the result consult if your test is positive.

Yes. If you have a typical-looking sore that is consistent with herpes, antiviral treatment has its strongest effect in the first 48 to 72 hours after the sore appears. Waiting for the swab result before starting treatment may mean missing this window. The Specialist GP can discuss starting treatment during your consult, and treatment is arranged on the call.

Your result is confidential. Your regular GP is not automatically notified unless you ask to be copied in, and the pathology lab keeps its own copy for its records as any lab does. If you would prefer to limit where your result is shared, mention it in your booking notes and the Specialist GP can arrange it when the kit is sent.
