I agree with you totally. I had a Tb done last Wed. and when I went back for my reading, I pulled my sleeve up and the nurse said " It's Positive", she didn't feel it until we went in the back, it was a little red like a rash but no visible bump, lump, nothing. Then she took a pen and marked the red area and measured the rash looking area. I have a lot of friends at the place and 4 of her co workers looked @ it and said it was negative, my friend who is a LPN said it was negative, I went back today to see if I could get another one done because of all the others opionions and she said no, I work with children in Headstart and need some advice on steps to take. I know she was wrong and I would hate for this to happen to someone else.
