Many types of self-tests are now available. Self-tests that have a medical purpose are in-vitro diagnostic medical devices. They can be used to diagnose a variety of conditions or to monitor a particular treatment. They can be purchased from many different sources including pharmacies and supermarkets.
While self-tests may have a role to play, they should not be relied upon on their own and it is important to remember that if you have any concerns about your health or a test result you should consult a healthcare professional.
This leaflet includes advice for people who are thinking about buying a self-test and highlights the potential risks associated with self-testing.
