Hi,
I'm a health care worker who has had to get PPDs for years now. At my old institution they used a PPD solution which gave me increasingly larger responses (they looked like huge mosquito bites and itched liked crazy - at its worst it was around 8 cm in diameter!) These were all read as negative for tb exposure because there was no "true induration." Later on I was told I had an allergy to something in the cocktail and so they switched me to Tubersol. It worked miracles, my first few PPDs had zero reaction. However, that was a few years back and now at my new hospital they say they also use Tubersol - but this time I got a 3 cm reaction with very mild itch.
Here's some other Hx: I have had hives twice in my life to temperature changes. I do have a family Hx of eczema and atopy. And I'm also VERY allergic to mosquito bites (similar reaction - HUGE wheals that last for 2 weeks and are extrememly itchy). Sigh - my skin sucks. Help?
