The POC testing analyzer i-STAT is a reliable alternative to the traditional blood gas analyzers and provides marginal improvement in turnaround time when compared with the service received from the PICU/NICU laboratory. The regression analysis (slope and correlation coefficient) of the results from instruments run with and without QC samples gave results close to 1, indicating that there is no need to run additional quality control (QC). A further study was made to assess whether routine quality control (QC) samples are necessary when using the i-STAT system. There was no significant difference in the results when operated by PICU/NICU nurses or laboratory personnel. Patients' results from the i-STAT correlated well with the Ciba Coming 288 blood gas analyzer (r = 0.99 for pH, pCO2 and pO2 and 0.95 to 0.99 for Na+ and K+) with the exception of iCa2+ (r = 0.73). Comparison of the i-STAT and the Ciba Coming 288 blood gas analyzer was assessed by split sample measurement. Linearity studies showed good linearity over the five different concentrations tested. Using whole blood studies the precision data gave %CVs that were < 3.5 for all the analytes. Each test cartridge contains chemically sensitive biosensors on a silicon chip that are configured to perform specific. Except for pO2, the %CVs were < 3.0 for all the analytes (pH, pCO2, Na+, K+ and iCa2+) at all the three concentrations. i-STAT 1 ANALYZER Immuno-Ready (no Glucose port) - a revolutionary, handheld analyzer provides reliable test results in just minutes, using as little as two drops of blood and a test cartridge. The system was evaluated for imprecision and linearity using three concentrations of aqueous standards. The reliability of the i-STAT system when performed by non-laboratory personnel was assessed. Comparison of patients' samples analyzed by the i-STAT system and the Ciba Coming 288 blood gas analyzer were performed. The i-STAT system was evaluated for imprecision, necessity of running quality control and accuracy. To evaluate the Point-of-Care (POC) i-STAT system for measuring blood gases (pH, pCO2, pO2) and whole blood electrolytes (sodium, Na+, potassium, K+ and ionized calcium, iCa2+) in the neonatal and pediatric intensive care units.
