Understanding Precision, Trueness and Accuracy

By Rodrigues, G.

Three brief videos break down recently-revised standards terminology to help you understand the background behind the change, and the importance of correct usage. Precision, trueness and accuracy: why are these terms important? Ensuring that everyone is speaking the same language is critical for communication between scientists in the laboratory. While precision and accuracy are generally […]

Volumetric Performance Assessment of Automated Liquid Handling Systems with ISO IWA 15

By Carle, A.B., Rodrigues, G.

In 2015, the International Organization for Standardization (ISO) published a new document, ISO IWA 15, which fills the void in ISO documents describing standardized ways of determining the performance of automated liquid handling systems. While ISO standards exist for the calibration of piston-operated pipettes and other volumetric apparatus (ISO 8655, parts 1 to 7) and volumetric glass pipettes (ISO 4787), there was no global document addressing the performance assessment of automated liquid handling systems. This void has been closed with the development and publication of ISO IWA 15…

Artel Lab Report eBook – your guide to liquid handling data quality

By Artel

When testing accuracy, precision and trueness of liquid handling instruments, how many data points should you test for each volume? Does pipetting technique impact data reproducibility and accuracy? How often should you calibrate your pipettes? Have you recently thought about your assays and how much variability in liquid handling they can tolerate? This eBook is intended to help users of pipettes and automated liquid handling systems find answers to questions just like these.

US Pharmacopeia Proposes Changes to Weighing Chapters

By Rodrigues, G.

Weighing is one of the most fundamental of laboratory tasks, and careful weighing is a central pillar supporting the generation of high-quality laboratory results. New proposals from the US Pharmacopeia (USP) are aiming to help clarify, explain and harmonize weighing best practices.  If enacted, these proposals will become legal requirements for some laboratories in the pharmaceutical […]

CMS Offers EP23 as Risk-Based Option for Clinical QC Plans

By Carle, A.B.

In two memoranda dated November 4, 2011 and March 9, 2012 the US Centers for Medicare and Medicaid Services (CMS) have informed laboratories of their intention to provide a new optional basis for laboratory quality control plans.  Guidance on this option is available as a revised standard, titled “Laboratory Quality Control Based on Risk Management” which was developed in […]

When Do Guidelines Become Requirements?

By Rodrigues, G.

MIQE Makes a Difference in PCR A guideline such as Minimum Information for Publication of Quantitative Real-time PCR Experiments (MIQE) is a good example of how a science-based guideline can impact customers and suppliers, becoming a kind of “voluntary regulation” which aims to improve the quality of laboratory research. Compliance with this guideline allows researchers and laboratories to […]

New ISO Standard Answers Growing Need for Data Integrity in the Laboratory

By Rodrigues, G.

Technologies often develop more quickly than regulatory agencies can respond. This is especially true in drug discovery and development due to the rapid pace of new technological breakthroughs.  Liquid delivery quality assurance is no different. In the face of advancing capabilities of liquid handling instrumentation, increasingly complex assays and an industry-wide push for greater efficiency, a […]

Taking Control of Your Quality Control

By Rodrigues, G.

Navigating Regulations and Standards for Liquid Delivery Verification Consider a quality control laboratory that processes 10 to 20 samples per day and releases as many as 20 batches of life-saving vaccines and pharmaceuticals each month. According to FDA stipulations, analytical results from tests performed by these laboratories are used to ensure the safety, purity and effectiveness […]

Metrological Traceability of In-House Calibrations

By Rodrigues, G.

Equipment calibration is a necessary and common fact of life in regulated laboratories, and the decision on how to calibrate often begins with a simple choice of whether to contract an outside service, or to keep it “in-house” and do it yourself. Laboratories have a variety of reasons for choosing in-house calibrations. Whether to enhance […]
