Concerned about Labcorp

Hello,

I used quick fix to take a labcorp pre-employment test this past Thursday. I had called Spectrum Labs, and it was an up to date batch. I got the temperature correct, and everything seemed fine. I received a call today from my future employer asking if I went in for the screening. I told them the location of where I went as naturally as possible. She said that she would try and contact them for the results. Should I have anything to be concerned about? I could see the lady making an error because of my poor handwriting. I also think that they might have sent out the sample for the preliminary testing. Should I expect a call from my employer saying they got the results? Should I have gotten a call from Labcorp, if there was an issue? Thanks everyone.
