Comparative analysis on detection results of 4 items of liver enzymology in 11 clinical laboratories of Xinjiang Production and Construction Corps / 国际检验医学杂志

ABSTRACT

Objective To understand the comparability of the detection results of four items (ALT ,AST , GGT ,ALP) of liver enzymology in 11 clinical laboratories in Xinjiang Production and Construction Corps (XPCC) and offer reference for improving mutual recognition of the results .Methods Eleven clinical labora-tories of XPCC organized the result comparability tests of 4 items of liver enzymology twice in 2017 ,and the samples with 5 batches were completed in each comparability test .One set of detection system in each labora-tory was used as comparability system according to comparability scheme .The detection results were analyzed through Robust Z Score and the evaluation criterion was :|Z|≤2 "satisfied";2< |Z|<3"warning";|Z|≥3 "not satisfied".Results The detection results of all 10 batch samples in 4 clinical laboratories showed |Z|≤2 in 2 comparability tests .In the first comparability test ,the detection results of 5 batch samples for 4 items were |Z|≤2 in 5 laboratories .In the second comparability test ,the detection results of 5 batch samples for 4 i-tems were |Z|≤2 in 8 laboratories ,but the ALT results of 5 batch samples in 1 laboratory showed positive deviation(Z≥3)and the GGT results of 5 batch samples in the other laboratory showed negative deviation (Z≤ -3) .Conclusion The 11 clinical laboratories in XPCC should continuously improve quality management system and make sure that the mutual recognition of the detection results of 4 items of liver enzymology is effective .
