Order an electronic ph-meter from ebay. They cost only around 10 dollars delivered to your mail box. They are precise, and a lot cheaper that papers. I use them in my work as a nutritional adviser with ph and gout as my special field of expertise.

The first thing to do, is to check urine ph and at the same time blood Uric Acid concentration with a cheap field meter that is precise and used in health-care around the world. They cost about 30-100 bucks.

If your blood UA reading is greater than 3,4 for men or 3,2 for women, it is too high. At 4,65 uric acids will start forming crystals.

If you have elevated blood UA concentration and your urine ph is above 7, you are suffering from chronic uremia. Your kidneys are unable to secrete uric acids from blood to urine.

Diazepam dilates kidneys' vascular system, and starts the UA secretion. This can be measured from blood and urine samples taken during first and second urination after the medication.
