Same thing happens to me. I finally learned to wait till the max amount of time to read the test and at that time, the redness becomes almost minimal. The only s/s I have is the readness--no raised area, heat, etc. Give yourself the maximum amount of time to have the test read; the redness should resolve by then...if not, you will get a CHX.
As I tell my patients: as long as you're not having a severe or life-threatening reaction to the PPD, try to ignore whatever the site does/looks like for the next 48-72 hours, since it's going to change quite a bit before it's time to be read. The closer you can go to 72 hours, the better. Don't attempt to self-read it because you will only work yourself into a frenzy. Try to stay calm and wait until you have it read.
Also, a positive PPD is not necessarily a clinical death sentence--they'll follow-up with a chest X-ray. If that turns out positive...then you may have to worry about rescheduling clinicals. But many people who have positive PPDs end up having negative X-rays.
If you are still very concerned, then the best person to get advice from is your healthcare provider.
My daughter is in a medical magnet program at her highschool and they have to get 2 TB tests when school starts. One of the girls in her class had a reaction to the nurse not doing the test correctly, she inserted the needle into the muscle tissue. It caused a reaction but when re-tested she was fine.
Calm down, no need to panic. I 'converted' to positive in 1986. Probably exposed to an undiagnosed patient in ICU - TB is endemic in my part of the country. I took prophylaxis meds for 6 months.... never had any active s&s and have had no problems since then. Just have to do the annual CXR instead of PPD.
Well it is 8/22 so you probably know if you have had a conversion yet. If you did convert, I would recommend getting the quantiFERON gold test (blood test). It tests for TB specifically unlike the PPD (it is possible to have a + PPD and no exposure to TB).
Also it is a good idea to hang on to (and make copies) of your documentation showing a + PPD. You will need it for virtually every job you apply for in the future.
Best of luck!

I've never had a reaction to one before! It's been 24 hr and I have a raised, red lump. If I hold it up to the light I can see the borders the size of a quarter. It's not blistery-looking or a pustule, it kind of resembles a mosquito bite. It's harder and warmer than the surrounding skin but it's not "knotty."
I was wondering if anyone else has ever had a similar experience with their PPD? Obviously, there's nothing I can do until the nurse reads my results tomorrow, but I'm freaking out because clinicals start next week.
