Table 2.

Serum concentrations (median ± IQR) of TK, c‐CRP, HPT, and 25(OH)D are shown for the 3 types of immune‐mediated disease studied. Significant differences between conditions were only identified between IMHA and IMPA for TK1 (P < 0.001)

	Disease Group
	IMHA	ITP	IMPA
TK1 (U/L)	36.75 ± 84.38	21.1 ± 38.75	4.15 ± 3.68
c‐CRP (mg/mL)	11.70 ± 48.18	11.55 ± 26.55	1.90 ± 7.00
HPT (mg/mL)	675.00 ± 294.30	230.85 ± 130.65	649.4 ± 216.40
25 (OH)D (ng/mL)	43.50 ± 20.80	62.8 ± 55.60	63.20 ± 30.72

c‐CRP, canine C‐reactive protein; HPT, haptoglobin; IMHA, immune‐mediated hemolytic anemia; IMPA, immune‐mediated polyarthropathy; ITP, immune‐mediated thrombocytopenia; 25(OH)D, 25‐hydroxyvitamin D; TK1, thymidine kinase 1.
