tb test results

[csuchick88]

A few weeks ago I got a letter stating I was exposed to someone with TB. I went in yesterday to get my TB test done at 1 pm. I go in tomorrow to have it read. It has been 29 hours and i already have a raised bump around d the injection site, I was wondering if it can show positive already or if it's possible to decrease by tomorrow at 1 pm and still be negative?
