Analysis of the Causes of the Unsuitable Blood Samples in Tumor Patients
Objective To investigate and analyze of the causes of unsuitable blood samples drawn from tumor patients. Methods From January 2010 to December 2011, a total of 379,991 blood specimens were received in our laboratory. The frequencies and types of cause of rejection samples were retrospectively evaluated. Results We find that 563 unqualified specimen because of poor quality control of preanalysis account for 0.15% of total blood count specimen. ESR(erythrocyte sedimentation rate) samples had the highest rejection rate of 1. 65 %. The second were thrombotest samples( 0.31%). The last were biochemical samples. Clot was found to be the major cause of rejection of samples, 52.22%, followed by insufficient sample volum, dilution by transfusion and incorrect container which gave a rejection rate of 22. 38%,6. 93% and 4. 62% respectively. Conclusion The quality control of preanalysis is the first step of total quality assurance of laboratory data and completed by the physicians and nurses. Therefore, the improvement of preanalysis quality control depends on the cooperation between the technologists and physicians and nurses.
