Percentiler- and Flagger programs

From 2019 Noklus takes over the day-to-day operations and development of these programs.

The Percentiler and Flagger programs

Patient medians and flagging rates are normally stable over time, and any change is usually due to pre-analytical or analytical instability or error. “The Percentiler” and “the Flagger” are tools for quality assurance in medical laboratories. In these programs, results from selected patient groups are used to calculate instrument- specific daily medians, as well as the percentage of patient results outside the reference limits. Laboratories can participate with results from a wide range of common clinical chemistry analytes and basic hematology. At present, more than one hundred laboratories from around the world participate in one or both programs, most with more than one analytical instrument. In early 2019, Noklus will take over day-to-day operations and development of the programs from Linda Thienpont/Dietmar Stöckl (Thienpont & Stöckl Wissenschaftliches Consulting GbR, before STT-Consulting). As of January 2019, participation is free of charge.

The Percentiler program:
  • Participating laboratories calculate, and report instrument-specific medians based on patient results. The total number of patient results is also reported.
  • Ideally, patient medians are reported daily, but less frequent reporting is also possible.
  • Results are exported to a central database by standardized e-mails.
The Flagger program:
  • Participating laboratories calculate, and report instrument-specific percentage of patient results above and below the reference limit.
  • Ideally, flagging rates are reported daily, but less frequent reporting is also possible.
  • Results are exported to a central database by standardized e-mails (containing an additional two columns compared to The Percentiler export).

Laboratories can choose to participate in the Percentiler program only.

Why participate?
Access to a laboratory’s results is only possible through their unique and individual account, but participants can compare their own patient medians to those of others in a dynamic and interactive visualization tool. For analytes with more than 20 participants, results are stratified according to type of instrument to allow further comparisons between laboratories using the same instrument. Furthermore, participation allows laboratories to follow their own patient medians and flagging rates over time. A detection of any change may, if necessary, allow the laboratory to initiate prompt investigations of possible pre-analytical or analytical issues. 

What does it take to participate?

Laboratories wishing to join the programs should contact Noklus to receive a protocol describing in detail how to report results.
