Abstract:
Objective To investigate the difference in complete blood count (CBC) within the defined time among 28 hospitals with different grade in Urumchi City, explore its influencing factors,offer the countermeasures, and further to provide scientific evidence for the mutual recognition among different medical institutions. Methods Totally 28 laboratories with different grade were enrolled in the investigation. Three fresh blood samples were employed to perform complete blood counting, in-cluding normal and pathological specimens. The measuring time and turn around time (TAT) were de-fined. Results According to the literature report on biological variability of testing results, the per-missible deviation of CBC was tentatively prescribed as follows: WBC 15% ;RBC 6% ;HB 7% ;HCT 6 % ;PLT 25 %. Qualification decision was based on the external quality assessment (EQA) criteria of Clinical Laboratory Centre of the Health Ministry. Qualification: the total score of five measured items is higher than or equal to 80%;disqualification: the total score of five measured items is lower than 80%. For the first and second sample, 26 laboratories (92.86%) were qualified;for the third sample (only 21 laboratories enrolled), 14 laboratories (67%) were qualified. Conclusion 28 laboratories par-ticipated in this test. The results of five items are congruent for the first and second sample (normalspecimens) in 28 laboratories, and the measured results are comparable. By contrast, the comparative result is unsatisfactory for the third sample (pathological specimen), mainly due to the narrow linear range of equipment. Meanwhile, the laboratory quality management should be strengthened.
