Do whatever you can to delay the test to give you more time. How badly you want to keep this job will determine the lengths you'll go to protect it so we can't help you there.
But if it were me and there was absolutely no way out of it and I really wanted to keep this job I'd be thinking up some kind of calamity that would allow me a few days to a week off. Beyond that, start drinking. Anything that'll flush out quickly (I suggest cranberry juice) and AVOID FATS OF ANY KIND! I also recommend a diuretic such as "Aqua-Ban" to help get rid of excess water build-up from all of the drinking you're doing. Then on day of the test be sure to empty the bladder as much as possible before giving them their specimen and take niacin or b-vitamin when you wake up to put color and weight back into the urine (too much raises suspicions too so don't go overboard with them). You will most likely pass but will probably be disqualified from being diluted but that's ok, you should be given another test in a day or two which gives you even more of that valuable time you need right now.

But still the best and sure-fire way to pass is by substitution. Especially for employment tests as they usually are not watched and if so not all that closely...usually.

Hope this helps and good luck!

DILUTION: tips, tricks and guidelines DILUTION: aka WATER LOADING FOR BEST RESULTS ABSTAIN FOR A BARE MINIMUM OF 48 HOURS BEFORE THE TEST AND THE LONGER, OF COURSE, THE BETTER YOUR CHANCES. Time permitting, 2-3 days before the test you will want to begin raising you Creatinine levels. Creatine, which metabolizes into Creatinine in 24-48 hours, can be raised with red meat and/or Creatine supplement, available on line or at nutritional food stores. The amounts of Creatinine metabolites are measured as part of the urine integrity Rating: 5
