[69] If microscopy is performed, knowing the pH of the sample helps to identify any crystals that might be ...
Maintenance of dilute urine by means of vigorous fluid therapy is beneficial in all forms of kidney stones, so increasing urine volume is a key principle for the prevention of kidney stones. Fluid intake should be sufficient to maintain a urine output of at least 2 litres (68 US fl oz) per day. [88]

Three different tests may be used to measure calcium levels in urine, 24-hour urine tests, blood tests, and genetic tests. Measuring calcium levels can also be done using an oral calcium tolerance test.

A diagnosis of primary hyperoxaluria is suspected based on presenting patient characteristics such as kidney stones in infants or children, recurrent kidney stones in adults, or family history of hyperoxaluria.
