Frequency of Sample Rejection and Associated Factors Among Clinical Specimens Referred for Diagnostic Testing to Adama Regional Public Health Laboratory

Abstract

There are occasions when laboratory tests could not be performed in site where the specimens have been collected and these specimens need to be transported to referral laboratories for diagnostic testing. The majority of laboratory errors emerge from the physically intensive activities of the pre analytical phase, mainly those related to collection, handling, transportation, preparation and storage of diagnostic specimens. So, sample rejection was one of quality indicators that compromise quality that compromise quality laboratory and patient’s satisfaction.
