Introduction. The determination of the electrolytes sodium and potassium is essential in
critical care. In daily clinical practice, both the blood gas analyzer (ABG) and the laboratory …

Background: We evaluated a new, 2-min blood creatinine method using the hand-held i-
STAT analyzer. Good results have already been reported using this analyzer for 10 methods …

Background Electrolyte values are measured in most critically ill intensive care unit (ICU)
patients using both an arterial blood gas analyzer (ABG) and a central laboratory auto …

We evaluated the performance of the i-STAT Portable Clinical Analyzer, a hand-held
instrument that, with its current cartridge, analyzes for electrolytes, urea nitrogen, glucose …

We measured the emf of NaCl solutions (120-160 mmol/L) with a home-built cell in steady-
state and with some commercial direct potentiometric analyzers about 20 s after the sample …

We measured the emf of NaCl solutions (120-160 mmol/L), with and without the addition of
KCl (5-20 mmol/L), CaCl2 (2-8 mmol/L), or MgCl2 (1-4 mmol/L). Measurements were made …

BACKGROUND: Measurements of free (ionized) calcium (iCa) are increasingly requested in
patient care locations where immediate analysis is unavailable. Evacuated blood collection …

Biomedical, Newton, MA) ion-selective electrode type of analyzer relative to that obtained
with flame photometry. They were concerned because their results were in disagreement …

Background: Lipemia affects electrolyte concentration obtained by indirect ion selective
electrode (ISE) method, but the specific influence on measurements by direct ion selective …

We evaluated the analytical performance of 10 representative channels on the new
microprocessor-controlled DuPont aca III according to the guidelines (draft documents PSEP …
