Method Comparison Study for Measuring Potassium (K) and Ionized Calcium (iCa) in Blood

Clinical Evaluation of the Potassium (K) and Ionized Calcium (iCa) Tests in Capillary Specimens Using the i-STAT CG8+ Cartridge With the i-STAT 1 Analyzer

Method comparison study for Potassium (K) and ionized calcium (iCa).

The objective of this study is to compare the performance of the K and iCa Tests using the IUO i-STAT CG8+ Cartridge on the i-STAT 1 Analyzer to the performance of the K and iCa Tests on the comparator device using capillary whole blood specimens. This objective will be assessed as part of a Method Comparison evaluation.
