If you're having the two-step, that first one "primes" your body's immune system for an enhanced reaction to the 2nd test. You could be negative to the first and positive with the second. Normally, you'll only need a 2-step test the first time you're tested, and after that, usually only a 1-step is needed if it's done annually.

Hello Everyone!
I Just had a TB step one done and it was Negative. Will Step 2 also be negative since step 1 was? I also had this done a year ago and both were negative.
Thanks
