Frequency and classification of errors in laboratory medicine at a veterinary teaching hospital in the United States

Abstract: Laboratory testing is an important part of case management and medical decision-making and begins when the choice is made to perform a diagnostic test. 1 Laboratories strive to produce precise, accurate data. 2-4 However, errors do occur, and factors outside of the laboratory itself can also influence sample results. 5 Errors in laboratory medicine can be divided into preanalytic, analytic, and postanalytic errors. 1,6-8 "Preanalytic" error occurs prior to actual sample testing and can include test selection a… Show more

“…Even if the influence of hemolysis, lipemia, or hyperbilirubinemia on test results of RBC and related variables as well as on PLT is well-documented, veterinary studies assessing the effects on the Diff are sparse. 27 Hemolysis with moderate-to-high hemoglobin concentrations, the most commonly observed interference in veterinary laboratories, 61 was associated with minimal effects on canine Diffs performed with the Sysmex XN-V analyzer. 27 The same was true for the interference by triglycerides and by bilirubin, given that no significant interference was demonstrated.…”

“…In both human and veterinary medicine, 60-75% of errors occur in the preanalytic phase, 10-30% in the postanalytic phase, and around 10% in the analytic phase. [22][23][24][25] In other words, up to 90% of errors occur outside of the analytic phase, during test selection, sample acquisition and transport, and result reporting and interpretation. As can be seen from Figure 2, most of these steps are under the control of clinical staff, and do not take place in the laboratory itself.…”

“…This is the phase of the laboratory testing cycle in which most errors occur, and poor quality assurance here can result in sample rejection or the need to repeat sample collection, inaccurate results, and misinterpretation of results. 24,25,36 Monitoring QA in this phase is based on the use of the KQIs listed in Box 1.…”
