An early diagnosis allows people to get treatment quickly and can prevent serious complications. And individuals successfully treated for HIV are less likely to pass the infection on. This new "do-it-yourself" test is made by company Bio Sure UK and can be bought online.
It works in a similar way to a pregnancy test, measuring levels of antibodies - proteins made in response to the virus - in a person's blood. The device analyses a small droplet of blood, taken from the finger-tip using a lancet. Two purple lines appear if it is positive. The company recommends attending sexual health clinics for advice and further blood tests if both lines appear.
