The Joint Commission has underlined this fact by stating that the laboratory is required to “systematically assess and improve important functions and work processes and their outcomes.”1It is therefore imperative to lay down certain benchmarks to assess laboratory functions.

Quality control Far too many laboratories consider quality control just a necessary evil, little more than periodic pass/fail exercises we perform solely to meet regulatory requirements. QUALITY CONTROL IN CLINICAL BIOCHEMISTRY LABORATORY: A GLIMPSE Samreen M Sheik* & Wilma Delphine Silvia CR Abstract Quality is defined as the conformance to satisfying the needs and expectations of the customers. Quality control (QC) is one of the most important impacts on laboratory testing—it ensures both precision and accuracy of patient sample results.

PubMed Google Scholar. Application of these techniques will help reduce errors and give both the laboratory and the clinician confidence in the results. 14 SUCCESS IN CLINICAL LABORATORY SCIENCE/Chapter 14 - Laboratory Management.pdf. There is a wide variation in laboratory practice with regard to implementation and review of internal quality control (IQC). IQC ensures that quality control and test samples are within the accepted range (12, 13). Accuracy can, as a rule, be checked only by the use of reference materials which have been assayed by reference methods. Application of these techniques will help reduce errors and give both the laboratory and the clinician confidence in the results. A poor approach can lead to a spectrum of scenarios from validation of incorrect patient results to over investigation of falsely rejected analytical runs. 1135 0 obj <>stream %%EOF The goal of making this Toolkit available is to assist primary care practices in their efforts to develop performance/quality communication indicators for clinically important gaps in pre- and post-analytic lab medicine.
