Answer 1

I Am in the healthcare field as a nurse and the first thing I can tell you is that it is not how the area looks but how it feels to the healthcare person reading the test. We don't measure the redness (erythema) , we actually measure the induration (thickness).

Answer 2

On the concept of tuberculosis, pathology, treatment and prevention, more detailed information here. Want to help you.

Answer 3

Negative should look like nothing, with the exception of a little redness where they administered the test. A positive result would look like a rash and/or a lot of redness around the site.

Answer 4

it is  measured by the  in duration (thickness).
