Any ideas on how to avoid a dilute ua? SWIM has to take random ua's and they tell her they are dilute. She has cut back her water intake but still comes up with dilutes. Any thing she can drink or take beforehand to avoid dilutes?
First of all dilute might not be the best thing for clearing the actual metabolites from one's system. Cranberry juice is highly acidic and is also a natural diuretic which will speed the elimination of water solubles from one's system.
A B-Vitamin complex, along with creatinine, will help with the color and the specific gravity of the urine and make it appear less dilute.
Just plain water is not enough, and can lead to problems like hyponatremaia, or water poisoning where the electrolytes are too diluted by the high levels of water that they cease to function properly.
Cranberry juice, is best, perhaps along with some sports drink. Coffee and alcohol are both diuretics also, but they may cause kidney and renal stress, so they should be avoided.
For more information have a look at SWIJasim's excellent posting regarding drug testing:
So cranberry juice will help with NOT getting a dilute? Does beverages like gatorade or poweraid help? She takes a multi-vitamin each day. What can help with specific gravity levels? Does working out or exercising help?
If she avoids water during the day or very minimal but drinks pop or other beverages can she still end up with a dilute? Unfortunately she has to take the ua's after work.
Urea has a big impact on the specific gravity of urine, so I'd speculate that low urea content is the reason the tests are registering as diluted. For someone eating a standard diet and urinating with normal frequency this should not pose a problem. It normally only occurs when someone is urinating excessively to purge their system. An extremely low protein diet may also have an impact, as urea is predominantly a means of clearing excess nitrogen, much of which comes from protein metabolism.
If SWIY is not attempting to interfere with the UA test by purging, then they should see their doctor and get a blood urea nitrogen (BUN) test done. High BUN is a sign of a form of kidney dysfunction (azotemia) and may be the reason for the tests seeming diluted. If the probation service are unhappy with the samples but SWIY knows they are clean then they could also suggest a hair follicle, blood or saliva test is performed as an alternative.
That's interesting that creatinine levels were flagged as the reason for the sample registering as invalid but not specific gravity. Creatinine is much like urea in that it a nitrogenous waste product and marker of renal function. Presumably the value you quote for SWIY is 15.9mg/dl (i.e. 15.9mg/100ml urine), which is certainly on the low side and would strongly suggest sample dilution to testers.
Attached is a pretty useful document from Redwood Toxicology that explains the use of creatinine testing in relation to cannabis testing, but also gives an overview of its general role in urinalysis. The most important part for SWIY is:

SWIY's urine creatinine concentration was on the very low side. If SWIY was not diluting the sample or drinking excessive fluids to purge then they really should get their kidney function checked out by a doctor. Redwood note that medical conditions such as type II diabetes can affect urine creatinine levels, and presumably many other conditions that affect renal function can too.
15.9 is just number without a unit of measurement. In the US it's typically reported as mg/dL and should have a range of around 25-260 mg/dL indicating that her urine creatinine levels are a bit low. I have to second what Phenoxide said regarding seeing a doctor and having kidney function tests. This could be a sign of some underlying medical problems.
