Table 2.

The table presents the results of the urinary UPC, uCr, UPCR, GGTP, FENa and FEK values; sCr-to-uCr ratio; GGTP-to-creatinine ratio and UPC-to-TP ratio in the studied healthy donkeys. Q1—first quartile and Q3—third quartile.

Parameter	Mean ± SD	Q1–Median–Q3	Range (Min.–Max.)
UPC (g/L)	0.32 ± 0.05	0.30–0.32–0.36	0.22–0.39
uCr (g/L)	11.99 ± 4.46	9.12–11.57–14.77	4.59–21.20
UPCR	0.29 ± 0.15	0.20–0.23–0.34	0.14–0.69
GGTP (U/L)	11.28 ± 4.96	7.7–8.9–14.1	6.7–20.90
GGTP/creatinine (U/g)	0.14 ± 0.69	5.35–9.18–12.18	3.41–20.81
FENa (%)	0.09 ± 0.04	0.06–0.08–0.09	0.05–0.17
FEK (%)	15.63 ± 6.69	10.28–14.79–19.78	5.89–30.18
sCr/uCr	0.660 ± 0.329	0.510–0.533–0.698	0.299–1.445
UPC/TP	0.0045 ± 0.0007	0.0041–0.0045–0.0048	0.0029–0.0058

Note: UPC—urine protein concentration, GGTP—gamma-glutamyl transferase, FENa—fractional excretion of sodium, FEK—fractional excretion of potassium, sCr/uCr—serum creatinine to urine creatinine ratio.
