I was diagnosed in May 2015, two and a half months after approaching my GP with five weeks of gastro issues, after having a flu in the January. I’d had a blood test and gave various samples; all returned no further action. Massive gap here for BBV testing, as this was in fact Sero conversion.
I visited a sexual health clinic in Birmingham, for no other reason than a routine sexual health check after the end of a relationship. I could still be undiagnosed today had I have not done that.
