| dc.description.abstract | Background: Accurate laboratory results are vital for patient safety and improving the medical diagnosis. Most errors occurred in the pre-analytic phase. Improper collection of samples can lead to sample rejection. In this case laboratory should establish rejection criteria and follow them closely. Specimen rejection may have significant consequences for patients and their clinical management. Thus, understanding the magnitude and taking appropriate action is critical for quality laboratory service provision. Objective: to assess the Specimen rejection rates and associated factors among samples referred to the laboratory of Addis Ababa Research and Emergency Management core process. Methods: cross sectional study was conducted using both primary and secondary data which assesses the rate and reason of rejection observed from June 01, 2018 to May 30, 2020 G.C. About 131,909 specimens collected at Addis Ababa Research and Emergency management core process laboratory with in the period of the study was entered and analyzed using SPSS 20. Result: a total of 131,909 specimens were sent to central reception of the Addis Ababa public health research and Emergence management core processes laboratory. The total rejection rate was 0.69%, 915. The frequencies of rejected specimens were highest in viral load 35.1%, followed by clinical chemistry which was 23.4%. The most common reason of rejection was mislabeling, 27.1%, followed by insufficient 15.8%, and clotted 15.1% specimen. Among rejected specimens, 514 specimens were rejected in the first and 401 Specimens were rejected in the second. Conclusions: The study demonstrated about 0.7% specimen rejection rate. Alongside of the efforts to minimize laboratory error, this study highlighted a complexity of pre-analytical errors to minimize them. The most commonly rejected specimens were for viral load followed by clinical chemistry samples. The most common pre analytical reason for specimens’ rejection was mislabeling, followed by insufficient and clotted specimens. | en_US |
