The amount of blood was insufficient for complete analysis in 0.08% (ie, 36 out of the 45,084 samples). et al. There is an urgent need to instill awareness about the intricacies of a seemingly easy and basic activity that forms the mainstay of laboratory services - phlebotomy among the staff engaged in sample collection in our hospitals to reduce inadvertent hemolysis. There has been varied information on the error rate within the whole lab testing procedure (0.1% to 9.3%). Nevertheless, it is mandatory for the laboratory staff to practice a certain basic level of workmanship and skillful phlebotomy techniques to reduce such errors to a minimum. The most frequent error encountered during processing was that of insufficient volume with an incidence of 0.37%. Southeast Asian J Trop Med Public Health. Hemolyzed specimens: major challenge for identifying and rejecting specimens in clinical laboratories. Notably, nonreceived samples were the most prevalent in ED (6.1%) and IPD (4.8%), while hemolysis (4.2%) was predominantly observed in OPD. . The pre-analytical phase comprises all processes from the time a laboratory request is made by a physician until the specimen is analyzed at the lab.

EJHaem. outside the analytical phase. 2004 Dec 1;88(3):161-81. doi: 10.1002/jso.20125. Some are predictable, whereas others are beyond control and must be understood in order to resolve and interpret appropriately (eg, cold agglutinins in winter seasons). A survey of our physician staff has shown that in the absence of such an interpretation, for patients being assessed for a coagulation disorder, approximately 75% of the cases would have involved some level of test result misinterpretation. Modern day diagnostics is not merely sample processing and preparation of reports. The analysis of the overall distribution of errors revealed that 89.6% were pre-analytical errors, 2.6% were analytical, and 7.7% were post-analytical errors. automated cell counting; general haematology; postanalytical; preanalytical; quality indicators. Trans Am Clin Climatol Assoc. [25]. Preanalytical errors were carefully determined and recorded. The occurrence of these errors was found to be highest in the ED (21%) as compared to the inpatient department (IPD; 13.4%) and the outpatient department (7%). DW Although the causes of these errors are largely common to all laboratory medicine specialties, it is important for the haematology laboratory to understand the particular impact of some on automated counting. Modern day diagnosis is heavily dependent upon reliable laboratory data. An official website of the United States government. A survey of our physician staff has shown that in the absence of such an interpretation, for patients being assessed for a coagulation disorder, approximately 75% of the cases would have involved some level of test result misinterpretation. 2020 Mar 20;12(3):e7335. MeSH The present study determined a rate of 12.1% of preanalytical errors from the total samples and laboratory requests received from the different departments. This comprised approximately 0.45% of all the samples received by the laboratory. A total of 55,345 laboratory requests and samples from different departments and wards were evaluated for preanalytical errors. In order to reduce errors in TTP, the pre-analytical phase should therefore be prioritized. 2011;47:399408.
