Well if you don't understand what retesting would do for you then why are you asking us about getting retested?
I'm sorry but I am thinking maybe you really,really need to discuss all of this with your treatment providers.I am thinking maybe it is possible you have all of it confused and you need to get it all straightened out with them.You are contradicting yourself in every post you make and it sounds like maybe even confusing yourself more.
I have nothing further to advise or suggest other than talk to them about it.Good luck with this.
