Thanks. It's not for kidney problems or any specific problem, actually, it's because I want to be sure I'm ingesting enough protein each day.

I do anerobic or aerobic exercise every day, and want to be certain I'm gettin sufficient protein.

I had read it's a 24 hour deal the 'official' way where you keep urinating in the same container for a day, but I thought there may be a way to self test it when you're done.

I am not a doctor (and I don't play one on television), but from my understanding of things this test would really not answer the question.

The book Protein Power, by Michael Eades, M.D. and Mary Dan Eades, M.D., states that a person of moderate physical activity should ingest not less than 0.6 gram of protein each day for each pound of lean body mass. Depending on activity level, this recommendation ranges from 0.5 gram (for sedentary people) to 0.9 gram (for athletes). This book has a formula for calculating your lean body mass based on certain measurements. Their subsequent book, Protein Power Life Plan, contains a table that allows you to ballpark a per-meal protein allocation based on your height and weight.

From what I can see, the results of a UUN test, standing alone, would really tell you little about the relation of your protein intake to your body's actual needs. It would tell you more about how your kidneys are functioning, and only then in conjunction with a serum urea test.
