Comparable appraisal of the blood ammonia test results of two different analyzers

Objective To analyze the comparability of the results of blood ammonia detection which was obtained by Pocket Chem BA blood ammonia analyzer and Vitros 350 chemistry analyzer, in order to further demonstrate the consistence of the two different test systems＇results. Methods The Pocket Chem BA blood ammonia analyzer was used as the laboratory method. The Vitros 350 chemistry analyzer was used as the comparison method. Results The diversity of two test results from the two analyzers was not statistically significant （ P 〉 0.05 ）. However, the analyzing results indicated that there was significant correlation between the two results （ P 〈 0.05 ）. Conclusion There is a high degree of consistency and comparability between the Pocket Chem BA blood ammonia analyzer and Vitros 350 chemistry analyzer. Due to its portable and quicker feature, Pocket Chem BA blood ammonia analyzer could apply in emergency medicine and intensive care unit testing, with the guarantee of accuracy of the test results.
