how long does it take for alcohol to get out of you blood and urine

One rule of thumb is 1 hour per unit of alcohol consumed.  In terms of driving - my advice is never to drink at all before driving.  After a heavy night out, dirnk lots of water and still question the need to put the key into the ignition until after lunch the next day.  If it's for a medical/military/sporting test, I'd say to play safe and not drink for 24 hours before hand.  I hope that helps!
