Abstract:
Objective To investigate the method and application of measurement uncertainty in clinical biochemical tests .Meth-ods The synthetic uncertainty and expanding uncertainty of 13 emergency biochemical tests items were compared between Hitachi 7600 and Beckman DXC800 automatic biochemical analyzer by usingmodel method.The test items included aspartate aminotrans-ferase ,total protein ,albumin ,glucose ,urea ,creatinine ,creatine kinase ,lactate dehydrogenase ,amylase ,potassium ,sodium ,calcium and chloride .Results Measurement uncertainty of aspartate aminotransferase and lactate dehydrogenase were 3 .66% and 3 .51%respectively ,which were the top two on Hitachi 7600 analyzer ;measurement uncertainty of calcium and creatinine were 4 .00% and 3 .90% respectively ,which were the top two on Beckman DXC800 .Compared between the two analyzers ,the test item with the lar-gest difference of measurement uncertainty was sodium(2 .62% ) ,and the second was creatinine(2 .40% ) .The difference of meas-urement uncertainty of the 13 emergency biochemical test items between the two analyzers were relatively small .Conclusion The two analyzer both have good performance ,Model methodis suitable for the evaluation of regular test items′measurement uncer-tainty in clinical biochemical laboratory .
