I know a woman on another site who's had issues with TB tests. If you want, I'll PM you the site or her myspace page. Let her know you're a friend of PiercedPsycho and ask her about TB, and she should give a shitload of info. Also, I have a friend who's training to be a doctor on this same other site, so you could ask him for some advice as well.
Other than that....I hope you're OK! Hugs from Sorsha.
