I recently peed in a cup to get a job. I passed an at home test the day before (with first piss o' the day), but was nervous after checking out this forum and reading a lot of hit and miss results from those at home tests.
ANYWAY....I only had to sweat for one day because I discovered that on my "Custody Control Form", the Lab your specimine is being sent to is listed, along with a number that you can use to check the status of your specimine through said Labs website. In my case it was CRL lab.
I checked it out and my specimines status was "results reported". This was only a few hours after they were received so I feel safe since they probably didn't have time in just a few hours to do all the additional checks necessary with a positive result. (Someone please correct me if I'm wrong here)
So yeah, my point is, if you're sitting around 4 days later wondering what your results were, maybe your CCF has this info on it too, so you can check it out and get some peace of mind. This might be old news, or maybe not standard on CCFs, but I figured id share if it could help out any of you nervous nellies that weren't aware.
