Since there are weak correlations (correlation coefficients: dogs 0.11, cats 0.27) between blood creatinine and UP/C (urinary protein/urinary creatinine ratio) in 62 dogs and 40 cats with suspected renal disease, UP/C is an independent index from blood creatinine. In addition, since blood creatinine was below the reference value (dogs 1.4mg/dl, cats 1.6mg/dl ) and indicated proteinuria in 24 dogs (38.7%) and 4 cats (10.0%), it was thought that the early stage and potential kidney disease that cannot be caught by blood creatinine could be detected by UP/C. Furthermore, since there were strong correlations (match rate within one rank: dogs 95.2%, cats 90.0%) between the quantitative method and the semi-quantitative method using a dipstick, it was considered that the rapid, simple measurement of UP/C in the hospital is effective by making use of the features of the dipstick method.
