I took my drug test 1-21-08. It was sent off to a lab called atn.I check the status on line on their web site. The results were reported 1-22 in less than 24 hours. My test was a 9 panel test. For the results review it has on the form ndot w/all review. I guess this is for the MRO. It is now 1-25 more than 4 days since I took the test and I have heard nothing. My employer has not heard nothing yet either. What is your opinion. The medical center said my employer would receive the results in 24-48 hours. This MRO is holding up my start date along with me firing one up after being clean for 50 days.
