Dear NRL QC Services Customers,

A global announcement was communicated recently that LGC has acquired DiaMex GmbH, the manufacturer of the Optitrol molecular and serology quality control products available in ANZ via NRL, Australia.
LGC recognises Optitrol as being best-in-class given the design and manufacture of the products according to NRL’s QConnect™ concept and expects that the range will complement and improve their existing quality control portfolio.

NRL’s commitment to the highest quality products and service always remains at the forefront of our operations as we work to ensure this change will not impact the day-to-day requirements of our loyal customers.
If you have any questions, concerns or feedback please don’t hesitate to reach out to us via [email protected]

Traditionally, laboratories set QC acceptance limits using as few as 15 data points and then calculate mean +/- 2 standard deviations to establish control limits.  Westgard rules are used to identify results that are “out of range”.  However, this method has been proven to be not fit for purpose and causes unnecessary work troubleshooting “false rejections”, resulting in extra cost and delays in patient testing.

As specialists in infectious disease quality control, NRL has developed and validated a more appropriate approach to monitoring infectious disease QC.  QConnect uses historical data submitted into our real-time QC software EDCNet, to calculate acceptance limits for each QC/Assay combination, using thousands of QC results.  In this way, participants can be confident that any QC results falling outside this range, truly represents an unexpected variation, which requires investigation.

NRL QConnect approach is the only scientifically validated way to monitor infectious disease testing QC results.

1. Highest quality control samples, using true human disease-state plasma, optimised for each test system
2. Data collection into the cloud-based EDCNet software
3. EQC test results, analysed against peer (EQC/Test Kit) test results, displayed in graphical and tabular forms
4. QConnect Limits, established using thousands of peer results, set upper and lower acceptance limits of EQC results, flagging when unacceptable results are detected.
