I have never had to read a TB skin test and I was asked by my husband's MD to read his since it was to be read on Saturday. When I went to read it I wasn't sure about one part of it. It was red, not worried about that. However, it was rough, like the skin dried out or something. This area was about 3mm x 5mm. It was not swollen. So I guess I wasn't sure how to write this on the form he has to fax back. Can anyone help?
