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, 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 preanalytical errors in phlebotomy 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 error in patient identification).3 It has been observed that diagnostic errors have led to the most prevalent type of malpractice claim in the United States.4 Although errors can arise at any of the three stages, studies show that the pre-analytical phase accounts for 46% to 68.2% of errors observed during the Total Testing Process (Table 1).5 Considerable advances in laboratory instrumentation have significantly reduced the error rate during the analytical phase.6 However, despite the improvements in pre-analytical automation, the pre-analytical phase remains the most error

In this minireview, we focus on this issue in the fields of laboratory medicine and blood transfusion. Methods: We conducted several MEDLINE queries and searched the literature by hand. Searches were limited to the last 8 years to identify results that were not biased by obsolete technology. In addition, data on the frequency and type of preanalytical errors in our institution were collected. Results: Our search revealed large heterogeneity in study designs and quality on this topic as well as relatively few available data and the lack of a shared definition of “laboratory error” (also referred to as “blunder”, “mistake”, “problem”, or “defect”). Despite these limitations, there was considerable concordance

On the morning of surgery, the patient was awakened by the phlebotomist who drew his blood for basic laboratories and type and cross-matching. To ensure proper patient identification, the hospital had implemented a policy requiring a registered nurse or physician to verify the identity of all patients screened for blood transfusion. In practice, after verification of identity, the nurse or physician was required to initial the patient label on the vial of blood. As it was the change of nursing shift, the bedside nurse for the patient was not available and there were no physicians on the floor at the time. With another floor of patients still to see, the phlebotomist carried the labeled vial of blood out to the nurses' station, and the label was signed by a random nurse. The sample was sent to the laboratory for analysis. Later that morning, a laboratory technician noticed a large and surprising ch
