Evaluation of Potassium (K) and Ionized Calcium (iCa) Tests Using Capillary Specimens

Clinical Evaluation of Potassium and Ionized Calcium Tests Using the i-STAT CG8+ Cartridge With the i-STAT 1 Analyzer for Capillary Specimens

The objective of this study is to compare the performance of blood tests using the i-STAT 1 System against a comparator blood analysis system.

To compare the performance of the i-STAT potassium (K) and ionized calcium (iCa) tests using the i-STAT CG8+ cartridge on the i-STAT 1 analyzer to the performance of K and iCa tests on a comparator blood analysis system using results from two separate capillary specimens from each subject enrolled in the study.
