Evaluation of a new instrument offering sodium, potassium, and ionized calcium in combination with haematocrit, pH and blood gas analysis; the performance of the Nova Stat Profile 1

Abstract

The Nova Stat Profile 1 analyser, a combined sodium, potassium, ionized calcium, haematocrit and conventional blood gas analyser, was evaluated over a four month period. In addition to assessing and demonstrating that the instrument met analytical requirements, an appreciation of the use of ionised calcium (iCa) was made. Prospective costs were characterised and practical problems of iCa measurement addressed.
