What should you know about a PCR test at home?

A home kit usually involves collecting a nasal, throat or saliva sample and sending it to a laboratory, although the exact method varies. PCR detects genetic material from the virus targeted by the kit. A detected result may support COVID-19, while a not-detected result does not rule out infection if the sample was taken too early, collected poorly or symptoms are changing. A home PCR test is different from a rapid antigen test kit: the methods, processing and reporting time can differ. Read the test provider's terms before relying on a result for travel, work or medical decisions.

Check the expiry date, wash your hands and follow every collection and packaging step. Avoid touching the swab tip or contaminating the container. Register the sample if required, send it through the stated route and keep the tracking or reference details. While waiting, limit close contact if you have symptoms or a known exposure, and follow local health advice. A clinician may recommend a formal COVID-19 test or repeat testing if the result does not fit your symptoms.

Seek emergency help for severe breathing difficulty, chest pain, blue or grey lips, new confusion, collapse or inability to stay awake. Contact a clinician promptly if fever persists, you are becoming dehydrated, symptoms worsen, or you are at higher risk of complications from COVID-19. Do not delay urgent care while waiting for a home result.

Ask which sample and laboratory process the kit uses, when the result is expected, what to do after a detected result, and whether you need an in-person assessment or repeat test. Check which symptoms require urgent help.
