Abstract:
Objective To investigate the status of blood specimen acceptability for clinical chemistry tests in routine medical laboratories of China. Methods The questionnaires were assigned to the laboratories which participated in the routine chemistry exter-nal quality assessment (EQA) programs proposed by National Health Commission for Clinical Laboratory. The questionnaires included general information of participants and information about unacceptable blood specimens. Participants were required to record all the in-formation concerning unacceptable blood specimen received from 1stto 31stJuly, 2017. The data from each laboratory were reported and collected via special online system.Results A total of 866 valid questionnaires were collected.Of 15 981 752 specimens received dur-ing the data collection period unqualified 122 00 specimens were rejected with overall rejection rate of 0.076%. The main reasons for unacceptable specimens were hemolysis (33.98%), insufficient specimen quantity (10.78%) and chylemia/lipemia (10.62%). The rejected specimens were related to the original laboratories, types of container and specimen, transportation manner and operating staff of blood collection. Conclusion Certain problems existed in the receiving and management system for unqualified blood specimen in our country and remaining to be perfected. The clinical laboratories should pay more attention for pre-examination stage, including routinely monitoring unacceptable specimens, analyzing related data at the most possible granular levels, identifying the main problem and taking effective measures.
