Investigating mechanisms to eliminate non-conforming events in the pre-analytical phase in oncology/hematology laboratories

Errors in laboratories are a common phenomenon. The hematology/oncology physicians primarily rely on results of samples taken to laboratories in order to make comprehensive inferences and diagnoses of the patients’ conditions. Therefore, the analysis of errors therein is impartial, as it is the only way through which the prevalence can be addressed making diagnosis more credible. This research involved the analysis of five laboratories, each of which participated for a period of one year, and recorded the incidences of pre-analytical errors. According to the data obtained, inadequate sample errors are the most prevalent at 61%, test order entry errors, followed at 37% with labeling and missing patient identities being reported as the least prevalent errors at 1%. Through this study, the reasons why the errors occurred have been identified and the resulting corrective measures discussed. Therefore, this study is monumental in the hematology/oncology laboratories as with remedies comes more perfection.
