Introduction: Specimen adequacy is a crucial preanalytical factor affecting accuracy and usefulness of test result. The aim of this study was to
determine the frequency and reasons for rejected haematology specimens, preanalytical variables which may affect specimen quality, and consequences
of rejection, and provide suggestions on monitoring quality indicators as to obtain a quality improvement.
Materials and methods: A cross-sectional survey was conducted and a questionnaire was sent to 1586 laboratories. Participants were asked to
provide general information about institution and practices on specimen management and record rejections and reasons for rejection from 1st to
31st July.
Results: A total survey response rate was 56% (890/1586). Of 10,181,036 tubes received during the data collection period, 11,447 (0.11%) were
rejected, and the sigma (σ) was 4.6. The main reason for unacceptable specimens was clotted specimen (57%). Rejected specimens were related
to source department, container type, container material type, transportation method and phlebotomy personnel. The recollection of 84% of the
rejected specimens was required. The median specimen processing delay in inpatient, outpatient and emergency department were 81.0 minutes,
57.0 minutes and 43.3 minutes, respectively.
Conclusions: Overall, rejection rate was a slightly lower than previously published data. In order to achieve a better quality in the preanalytical
phase, haematology laboratories in China should pay more attention on training for phlebotomy and sample transportation, identify main reasons
for clotted specimen and take effective measures. The platform in the study will be helpful for long-term monitoring, but simplification and modification
should be introduced in the following investigation.
