EXPRESS DIAGNOSTIC AID FOR UROLITHIASIS IN CATS AND METHOD FOR MAKING THEREOF Russian patent published in 2009 - IPC G01N33/493 G01N33/487 A01K1/15 

FIELD: medicine, veterinary science.

SUBSTANCE: invention refers to veterinary science. An express diagnostic aid for urolithiasis in cats is indicator granules containing a base and a mixed indicator with said dry mixed indicator and base taken in the ratio 0.01-0.04. The base is fractionated Circulite coated with a mixed indicator fluid containing as follows, wt %: distilled water - 50-89.9%; a water-soluble polymer 10-49.9%; a water-soluble pH indicator - 0.01-0.1 %. The water-soluble polymer is either polyvinylpyrrolidone, or polyethylene glycol, or polymethacrylamide, or polyvinyl alcohol. The water-soluble pH indicator is phenol red and/or cresol red, and/or chinoline blue, and/or rosolic acid, and/or corallin algae, and/or nitrasin yellow, and/or curcumine. The method consists as follows: The mixed indicator fluid is solubilised. The prepared mixed indicator coats the base of Circulite granules fractionated by nozzle spraying at discharge 100-200 ml/min and at sprayed solution temperature 20-40°C. The granules are dried up to humidity 1-5% at temperature +40 to +250°C during 5-30 minutes to ensure the ratio of the dry mixed indicator to the base within 0.01-0.04.

EFFECT: enabled express diagnostics of urolithiasis.
