Thanks both,
We are going to e mail our urologist and ask the question. There appear to be four broadly similar tests available ( see link) but I have not researched in any depth as thought i would ask first.

It does seem sensible to get as much Intel as possible about these low risk diagnosis given the acknowledged problem with over treatment. on these guys, the impact that unnecessary treatment has on their lives but also the resources being used both in the radical treatments themselves but then the ED resources that could be redirected to the guys for whom a radical treatment and ED support is essential.
I will let you know what he says and keep researching to see if its been discredited or even trialled. I will ring the companies direct as that often is easiest. I will been aware of their economic interest in their products and have professional scepticism built in to my profession so will be applying as ever.
Regards
Clare
