No lay person should read their own TB skin test. They don't have the knowledge or the background to know what is normal and what is not. I read my own TB skin test at home over the weekend when I had been required to get it done immediately due a known exposure several weeks before that was just confirmed. Well, it was grossly positive. Even I, a trained nurse, had wondered what was going on with the redness on my arm because I had forgotten about the test. Then the lightbulb came on and I realized what it was. A layperson could have chalked it up to a bug bite or a reaction to some other substance, especially if it was as large as mine was - nearly my entire forearm.
No patient should be reading their own, because that is a risk, because they are not taught how to evaluate it, and plenty of times, I have had to either get a second nurse or a doctor to evaluate behind me.
I do know that some of nurses that have administered a PPD for their fellow collague, and then, the collague will tell their friend whether it was regular or positive (because she can't come in that day, was off, on vacation...and the friend will document). Not quite the right thing to do, but I am not surprized.
It is too important not to have a nurse confirm the result. Even if the subject is a nurse, a second opinion is appropriate for documentation purposes if nothing else.
I know...that's why I say that it is not really the correct thing to do. It is amazing, some of the things I see nurses do for each other that can cause problems if not being careful. I wouldn't want the guilt of possibly letting a friend walk away with a positive PPD and no follow up.

Redness isn't the issue. It's the induration. Even then, different mm of induration are + for people in different categories. check this on a health department site for particulars.
I can't say that's its proper, but I saw a lot of that in LTC. A nurse would get her PPD, she'd have 3 days off and didn't want to drive back in to have it read and would call another nurse and say, "It's good." And the second nurse would chart 0.0 mm reading and sign off.
Like I said not proper, but done. And I plead the fifth.

:uhoh21:Is it ever ok to have a person "read" their own PPD , and call the nurse if there is anything "unusual"?
