One in five HIV positive people in the UK remain undiagnosed. Despite this, HIV testing is not routine. Now a new campaign in London aims to change this.

Becky meets the patients being tested and the doctor spearheading the campaign to ask if this is the most efficient way to tackle the HIV epidemic.
