QC Monitoring

At A Glance

  • The company is the world leader in serving science, with revenues of more than $20 billion and approximately 65,000 employees globally.
  • They needed a web-based quality control monitoring application to replace their existing paper-based system.
  • It was important that the systems allow the users the ability to input data in a number of different ways.

The Primero Solution

  • Primero developed a web-based quality control system to allow the company the ability to abandon their more error-prone and less efficient paper-based system.


  • Improved efficiencies due to less reliance on manual data entry via paper.
  • Higher customer satisfaction due to the multiple data entry modes available, including manual entry via the website, batch entry, and auto-upload directly from the LIS and/or analyzers.
  • Immediate reporting instead of waiting for faxed or mailed reports.
  • Instant peer comparison to allow users to instantly see how their data sets compare to their peers.

The Challenge

Around 10 years ago, this partner needed a web-based quality control monitoring application to replace their existing paper-based systems. The cost to scale their existing process didn’t make financial or operational business sense for continued investment.

The Solution

Primero Systems has designed and deployed (and is actively developing, enhancing and maintaining) a system for this partner, which processes thousands of quality control statistics in real time. Some of the world’s most respected hospitals and companies trust our system to check and track their data.

Clinical laboratories around the globe submit QC test results from their instruments to this platform, which stores the data and provides peer statistics back to the laboratories. This in turn, helps the labs to detect suspicious results that can identify an issue with an instrument, a trend, or just confirm acceptable values.

One of the key features is real-time peer data comparison, relieving the labs from having to wait for hours to review peer statistics and allowing for faster troubleshooting. It can compare QC data with other labs around the globe or just with the lab’s affiliated network.

Submissions can be done manually by the lab users on the website, although automatic data entry is encouraged, providing faster input and eliminating manual errors.

Every data point added to the system is exposed to different validation algorithms, ensuring that outliers are excluded from the process. Some algorithms are based on fixed ranges, others on auto-calculated ranges obtained from statistics. There are also “violation rules algorithms” integrated into the system; Westgard Rules and Rilibak among others.

The system provides more than twenty types of PDF reports for the labs to review, including standard graph analysis like Levey Jennings and Youden. The system supports Review and Approve workflows for data submissions, ensuring that each data point is reviewed and approved/decline by the lab’s personnel if required.

Besides static reporting, the system offers interactive visualizations of Levey Jennings charts, allowing users to the set time ranges, compare with other instruments, include comments, and multiple types of visualizations.
