Abstract

Thirty-one healthy pet cats had voided urine samples collected prior to, during and after a brief period of hospitalisation. Urinary corticoids were measured, both prior to and following an extraction technique, and the urinary corticoid:creatinine ratio (UCCR) was calculated. Associations between the UCCR and age, sex, breed and time of urine collection were investigated. There was no significant relationship established between age, sex and breed and the UCCR. A significant increase in the UCCR, however, did occur between the first home collected and first hospitalised urine sample, but only when comparing extracted corticoid results. A normal range for feline UCCR is established for the chemiluminescent immunoassay used in this study.

Box–whisker plot of extracted UCCR at the four different collection times. The boxes represent the 25th and 75th percentiles and the horizontal line the median. The whiskers encompass the bulk of the data, excluding outliers, and in most cases represent the range. Outliers are shown as circles. A significant difference was present between time 1 and time 2 (p<0.001), and between time 2 and time 4 (p=0.010).

Box–whisker plot of non-extracted UCCR at the four different collection times. The boxes represent the 25th and 75th percentiles and the horizontal line the median. The whiskers encompass the bulk of the data, excluding outliers, and in most cases represent the range. Outliers are shown as circles, ○. No significant difference was found between the different collection times.
