Six QC recommendations to consider today »
An important goal of laboratory medicine is to improve patient health by providing laboratory results that support medical decisions. Meeting this goal requires reporting accurate results that enhance care while minimizing patient risk. It is no longer satisfactory for a laboratory’s Quality Control (QC) to simply focus on taking care of the instruments—treating the instruments as if they are the laboratory’s “patients.” Since publication of risk management guidelines such as ISO 151891 and CLSI EP232 , the laboratory is now expected to design its QC with a focus on the patient: How does the QC plan effectively mitigate risk of patient harm from erroneous reported patient results?

Don’t rely solely on Sigma values to determine QC frequency »
Laboratories know that appropriate quality control (QC) rule selection depends on the in-control performance of a test method (the Sigma value). Higher performing tests may allow “easier” rules, while lower performing tests require more powerful rules. In recent years, QC frequency has undergone a shift in thinking and approach related to patient risk-based QC design. That is, what we are asking now is, what is an appropriate QC frequency to assure that the risk of patient harm from an erroneous reported patient result is acceptable?

Measurement of Uncertainty »
Whether you are measuring an object with a ruler, weighing items on a scale, or running complex assays, you will never be able to achieve exactly the same measurement every time. Each time something is measured, the result will vary slightly, and it is therefore impossible to attain a single true measurement value.

Optimize Quality Control Data Management with Bio-Rad’s Unity Real Time Software »
Automation continues to gain importance in modern clinical laboratories in step with increasing test consolidation, rising demands from clinicians for rapid turnaround times, and an ever-mounting shortage of licensed medical technologists. Ultimately, the laboratories that implement high-quality automation solutions are better equipped to meet these modern demands.

Practical Guide to Six Sigma in the Clinical Laby »
Six Sigma is a quality management strategy that categorizes process capability by evaluating how many process standard deviations can fit within the tolerance limits of the process. The more standard deviations – or sigmas that fit between the mean of the process and the tolerance limits, the more robust the process will be.

Exploring the Cost of Quality in the Laboratory »
“Prevention is better than cure” is a statement frequently used in medicine and healthcare, and it also applies to quality systems used in the laboratory.

Quality Control in the Evolving Landscape of Molecular Diagnostics Testing »
A laboratory in a cutting-edge field like molecular infectious disease testing merits an exceptional quality control program to strengthen confidence in lab performance and support excellent patient care. However, for the relatively new segment of molecular diagnostics, QC standards and regulations are not as well-defined as more traditional areas of in vitro diagnostics.
