Table 1.

Intact and whole PTH concentrations (measured in pmol/L), the ratio of whole to intact PTH concentrations, osteocalcin (ng/mL), and ICTP (ng/mL) concentrations and the urine NTX to creatinine ratio in dogs with hyperadrenocorticism and a hospital control population.

		Intact PTH	Whole PTH	PTH ratio	Osteocalcin	ICTP	Urine NTX ratio
HAC	Median	9.25	4.61	0.53	3.18	2.98	160.2 ± 84.1*
	Minimum	1.34	0.56	0.28	0.70	1.15	30.3
	Maximum	95.45	125.16	1.31	12.36	6.62	300.3
Control	Median	3.88	1.83	0.46	3.63	7.30	128.8
	Minimum	2.01	0.88	0.36	2.00	3.68	64.8
	Maximum	10.31	6.81	1.80	15.08	21.25	384.6

The number of dogs for each measurement are illustrated in Figure 3. PTH, parathyroid hormone; ICTP, carboxy-terminal cross-linked telopeptide of type 1 collagen; NTX, amino-terminal cross-linked telopeptide of type 1 collagen; HAC, hyperadrenocorticism. *Urine NTX ratio is reported as mean ± sd as it was normally distributed.
