Urinary Calculi

Calculus Tests Contained In This Kit:
A complete ready-for-use reagent kit for semi-quantitative determination of the most important components of urinary calculi, i.e. uric acid, cystine, phosphate, magnesium, ammonium, calcium and oxalate.

Method:Chemical, Manual

Uric acid is detected by reduction of alkaline phosphotungstate to tungsten blue; cystine by the red color formed in the cyanide-nitroprusside test; phosphate by the blue color formed by reduction of molybdatophosphoric acid to molybdenum blue; magnesium by the red color developed with xylidyl blue; ammonium ions are assayed using Nessler’s reaction. Calcium is measured by titration against Titriplex III; oxalate by the color formed in reacting with iron chloride and sulphosalicylic acid. The various salts of particular ions can then be determined using the specially-calibrated ruler provided.

The excreted stone must be crushed to a homogeneous powder, which is then made in to a solution and used in all subsequent tests.
