RN Sheri

If it's a two-step, you will be having a second test placed. With the Mantoux process, the second step isn't done in case the first wasn't done properly, but, if the second one is placed properly (with a resulting wheal), I'd take comfort at least one was done properly and trust the result of the second test. Where I work, clients are only tested with one-step as they aren't with us long. If one test is good enough for the transient population, one should be good enough for the rest of us. In the past, whenever I needed a TB test for employment as a RN, I'd go to the health department--they never made me take a second test & I was able to work.
