Maybe I shouldn't be reading too far ahead,

I have done some reading on the above two tests and am wondering if they HAVE to be done. I am really bad with needles (ie throwing up and fainting) and have quite a low pain threshold (despite having 5 tatts )

I know what they do and the reasons people have them done, I guess I am looking for some first hand experience on how others have been with either or both of these tests.

I am 31 yrs and in good health.

Thanks all
