Comparison of Measurements of 12 Analytes in Equine Blood Samples Using the In-Practice Falcor 350 and the Reference KoneLab 30i Analysers

Table 3

Data from Bland-Altman difference plots used to determine agreement between the Falcor and KoneLab analysers.

Analyte	Bias	95% CI for the bias
Albumin	1.9	1.5 to 2.3
ALP	237	196 to 278
AST	−54	−84 to −24
tCa	0.2	0.1 to 0.2
CK	−35	−58 to −12
Creatinine	−6	−9.2 to −2.9
Phosphate	0	0 to 0.1
K^+	−0.4	−0.4 to −0.3
Na^+	−0.2	−0.8 to 0.5
TB	−2.2	−3.2 to −1.1
TP	1.4	0.7 to 2.2
Urea	1.8	0.5 to 3.1

CI: confidence intervals, TP: total proteins, CK: creatine kinase, ALP: alkaline phosphatase, AST: aspartate aminotransferase, TB: total bilirubin, tCa: total calcium, Na⁺: sodium, K⁺: potassium.
