The urine protein/creatinine (UPC) ratio is a simple test that measures how much protein is being lost through the kidneys, and determines if the loss poses a health risk for the pet. The test gives an indication of kidney function.
The test involves measuring the amount of protein and creatinine in a urine sample, and mathematically dividing the protein value by the creatinine value.
Readings of up to 1.0 are considered normal however it is recommended that dogs with a reading of greater than 0.3 should not be bred from.
