Abstract: Objective: To explore the influencing factors of clinical routine biochemical test results, and put forward corresponding preventive countermeasure. Methods: A retrospective analysis was carried out for the biochemical detection test results of 10256 hospitalized cases from February, 2012 to February, 2013. Three levels quality fix value products of American BIORAD company were detected before the test, during the test and after the test to find analysis fault. The causes of error were classified as the source of produced in the biochemical detection test, just as the error before the test, during the test and after the test. Results: 84 error cases which had been re-checked in all test results were found and the deviations were more than 10% than their real value. It accounted for 0.82% of the total analysis cases. The main errors happened before experiment process which accounted for 78.57% of the overall produces deviation. Factors of patients and the specimens misconduct constituted the main body of before the experiment process interference factors, accounted for 39.39% and 36.36% of the errors factors from before the experiment process. Unknown cause hemolysis and improper specimen collection method were also the errors reasons which caused before the experiment interference. Instrument failure,reagent expiration or expired, calibration or calibration curve expired respectively accounted for 46.67%, 33.33%, 20% of experiment factors. After the experiment interference factors were test reports disqualifications which were caused by results checked carelessly or not in time. Conclusion: In clinical routine biochemical examination process, any link wrong could affect the results, especially the patient factors, improper specimen collection method and improper handling. The medical staffs should pay attention to these causes.
