Quick Turn Studies



Scheduled studies vs. Quick Turn studies

Most proficiency testing is run on a pre-defined schedule meaning that you will receive the samples when the study begins. Your lab then has the full duration of the study (usually 45 days) to analyse and submit the results. Once the study closes, it takes approximately 21 days to receive the final evaluation.

A Quick-Turn PT is a proficiency test that is not run on a pre-defined schedule; you can request a quick turn PT at any time. The ‘study’ is closed once the analysis is completed and you have submitted the results to the PT reporting system. The final reports are sent out within 48 hours.

Quick-Turn Studies
When you need to perform a Proficiency Test at short notice, Quick-Turn PT rounds are available for the majority of the RTC sample portfolio. Quick-Turns are provided at the same price as our scheduled samples.
In most cases laboratories can usually use these samples for:

  • Supporting new method validation
  • As a tool for corrective action
  • To demonstrate analytical competence
  • To train new lab personnel
