A follow-up validation experiment was performed, in which our objectives were to (1) assess the performance of the prototype cow-side against the POC VS (farm gold-standard) using fresh non-anticoagulated whole-blood samples (2) assess the performance of the prototype and the POC VS against the RA in a diagnostic laboratory using blood collected in a heparin-balanced syringe and (3) assess the agreement of the prototype and POC VS on-farm (fresh non-anticoagulated whole blood) against the RA on heparin-balanced blood. Coefficient of variation on 3 samples with high, within-range, and low iCa concentrations ranged from 1.0 to 3.9% for the prototype. A linearity experiment showed no deviation from linearity over a range of iCa concentrations compared with a commercial point-of-care (POC) device commonly used in the field (POC VS VetScan i-STAT, Abaxis North America, Union City, CA) and a laboratory gold standard benchtop blood-gas analyzer. ![]() The objective of this study was to assess an optimized ion-selective electrode Ca-module prototype as a potential cow-side device for ionized Ca (iCa) measurements in bovine blood. ![]()
