I realise I might be resurrecting a zombie thread here but I came looking for a thread on this topic and didn't want to start a new one.
For personal reasons I don't want to get into, I recently decided to use the home testing kits instead of going to the GP's surgery.
Opting out from the service has been very difficult and almost intrusive. I filled in the form online and said I fully understood the ramifications. The following day I got a call from my Dr's surgery from a nurse who said she'd received the form, but 'wouldn't accept it' unless I first listened to her explain why I shouldn't do this. She asked for my reasons why but I was in an open plan office at the time and wasn't about to get into it. I said I didn't want to explain right there so she said she'd call me back. She did - 2 times but I missed both calls as I was in a meeting.
I continued to receive letters and so I filled in the form again and then got another call from my surgery. I was a bit annoyed at why she needed to know my 'why' and my inner stubborn ass decided it was none of her business.
I'm a grown adult who can make her own decisions. I just said again that I didn't want to disclose. FINALLY, I got a final call from the GP's receptionist asking me to go in and sign a disclaimer. When I went down to the surgery and gave my name, the receptionist couldn't find the form so she went into a side room and I heard her say 'the lady who wants to opt out of cervical screening is here'. Another woman comes out the back room, hands me an envelope and I swear she was about to ask me something but I just said 'thank you' and then I signed the form and left.
In conclusion I'd say that these tests are important and vital for many if not all but there will be some who choose not to go (for personal reasons) or opt out. If you have made an informed choice then I do believe the process should be easy. My informed choice should be enough and I don't think I should have to give my reasons.
