Abstract

 Background: Quality assurance in the HEMATOLOGY laboratory is a must to ensure laboratory users of reliable test results with high degree of precision and accuracy.Even after so many advances in HEMATOLOGY laboratory practice, pre-analytical errors remain a challenge for practicing pathologists. This study was undertaken with an objective to evaluate the types and frequency of PREANALYTICAL errors in HEMATOLOGY laboratory of our center.Methods: All the samples received in the HEMATOLOGY Laboratory of Dayanand Medical College and Hospital, Ludhiana, India over a period of one year (July 2013-July 2014) were included in the study and PREANALYTICAL variables like clotted samples, quantity not sufficient, wrong sample, without label, wrong label were studied.Results: Of 4, 71, 006 samples received in the laboratory, PREANALYTICAL errors, as per the above mentioned categories was found in 1802 samples. The most common error was clotted samples (1332 samples, 0.28% of the total samples) followed by quantity not sufficient (328 sample, 0.06%), wrong sample (96 samples, 0.02%), without label (24 samples, 0.005%) and wrong label (22 samples, 0.005%) Conclusion: PREANALYTICAL errors are frequent in laboratories and can be corrected by regular analysis of the variables involved. Rectification can be done by regular education of the staff.
