how long for u/a results

I took a urine test today to return to work after previously failing one. Does anyone know from past experience how long it takes for results to come back?
This is a d.o.t test if that makes a difference and i know that it will be clean I haven't smoked in over 35 days. and have been home testing for about a week now. Any feedback would be greatly appreciated I haven't worked in a month and i am running out of money just want to have an idea on how long this will take.....Thankyou

It takes 3 business days for the labs to have the results. Then its up to the company to let you know.
