Pre-analytical errors: their impact and how to minimize them By: Nitin Kaushik By: Sol Green May 18, 2014 0 14987 The pre analytical error definition clinical laboratory plays an increasingly important role in the patient-centered post analytical errors approach to the delivery of healthcare services. Physicians rely on accurate laboratory test results for proper preanalytical errors in phlebotomy disease diagnosis and for guiding therapy; it is estimated that more than 70% of clinical decisions are based on information derived from laboratory test results.1 The preanalytical errors in clinical laboratory ppt process of blood testing, also known as the “Total Testing Process,” begins and ends with the patient. It includes the entire process from ordering the test to interpretation of the test results by the clinician. The Total Testing Process can be subdivided into three stages: Pre-analytical: test request, patient and specimen identification,
What Is Preanalytical
specimen collection, transport, accessioning and processing Analytical: specimen testing Post-analytical: reporting test results, interpretation, follow up, storage, retesting if needed. Additionally, the term “pre-pre-analytical phase” has been used for the initial part of the pre-analytical phase, focused on test selection and identification of test needed, and the term “post-post-analytical phase” has been used for the interpretation of results by the clinician.2 The numbers don’t lie: it’s a significant problem Clinical laboratory errors directly lead to increased healthcare costs and decreased patient satisfaction. A laboratory error is defined as any defect that occurs during the entire testing process, from ordering tests to reporting results, that in any way influences the quality of laboratory services.3 Any error during the laboratory testing process can affect patient care, including delay in reporting, unnecessary redraws, misdiagnosis, and improper treatment. Sometimes, these errors may even be fatal (e.g., acute hemolytic reaction after incompatible blood transfusion caused by an err

Effective laboratory service is the amalgamation of precision, accuracy, and speed of reports delivered to the patient. In spite of rapid advances in laboratory science, it is still susceptible to various manual and systemic errors. Various types of errors that we, as clinical biochemists, encounter in the laboratory are classified as preanalytical, analytical, and postanalytical, depending upon the time of presentation. The preanalytical phase is an important component of laboratory medicine [1]. It includes specimen collection, handling and processing variables, physiological variables, and endogenous variables. Some of the preanalytical variables such as specimen variables can be controlled, while knowledge of uncontrol
