How long does alcohol stay in youre system for a urine test?

To put it plainly, I drank Friday night until approximately 11:00- 11:30 pm I had a urine test (LAB) on Monday at 10:00 am. Will the alcohol show on the test? The last time I drank it was on a Saturday night into Sunday morning. When I took the test on Monday It showed up but at really low levels. Please only answer if you know from experience, and no criticism PLEASE !! Thanks
