Résumé
Objective:To analyze statistically the results of potassium, sodium, chlorine tests by blood-gas biochemical analyzer and automatic biochemical analyzer, in order to have a reference data for blood-gas biochemical analyzer in emergency biochemistry examination.Methods: A total of 101 cases were selected in emergency department. Arterial and venous blood samples of these cases were drawn and tested in electrolyte examination by blood-gas biochemical analyzer and automatic biochemical analyzer. The results of both instruments measured were analyzed statistically.Results: The results of potassium, sodium, chloride ion concentrations tested by blood-gas analyzer ABL80 were lower than the results tested by Beckman AU5800 automatic biochemical analyzer. The correlation analysis were performed in each tested item between the two instruments, and the differences were statistically significant(r=0.997,r=0.992,r=0.989;P<0.05).Conclusion: Although there were differences between two instruments in testing potassium, sodium and chloride ion concentration, the correlation was significant in each test item between the two instruments and the testing speed of blood-gas analyzer ABL80 is faster than the other. Therefore, in order to make quick and accurate clinical judgments about patient's condition, it is worth using blood-gas biochemical analyzer for a preliminary reference in clinical application.
