Urine Test

I have been a heavy drink but now have been clean for 2 days, when could I pass a urine test? Does any one know?
Hi ,
I read not long ago that alcohol is only readable in a urine test for 8 - 14 hrs, dont know how true that is but thats what I read.
I've never heard of a urine test for alcohol but I could be wrong. Urine tests are usually for drugs. Breathalyzers are for alcohol.
They screen for both down this way, I have just had one done for pre employment medical.
