Final OOS SOP

20 August 2014

The ECA Working Group "Analytical Quality Control" was founded in 2010. Its first project was the development of a single SOP for the handling of analytical deviations within the laboratory - including OOS, OOE and OOT results.

In the first step of this project, an SOP flowchart was developed which was then evaluated by the ECA OOS review team with over 100 ECA members. In the second step, a draft of the OOS SOP was developed using the already coordinated flowcharts. To this OOS SOP draft the review team members submitted approximately 25 responses - comprising many detailed suggestions and comments for the final OOS SOP.

This OOS SOP was presented and discussed during the OOS Forum in Prague, Czech Republic, in June 2012. One of the main objectives of the OOS Forum was to introduce the ECA OOS SOP to a wider audience and to discuss other alternative approaches of a GMP-compliant handling of OOS results.

At the OOS Forum members of the review team presented opinions and approaches, which deviated from the process described in the ECA OOS SOP. These notes were still considered in the final revision of the OOS SOP.

Meanwhile, the final version 2.1 of this SOP is now available as a free download in the ECA members' area.

During the development phase of the OOS SOP it showed that the handling of Out of Expectation (OOE) and Out of Trend (OOT) results can not be covered in the same document as the subjects OOE and OOT are much too complex, to address all relevant aspects in an SOP.

Therefore, the ECA QC Working Group is planning the creation of a separate SOP on OOE and OOT. The first draft of this SOP will be presented at the OOT Forum 2014 from 22-23 October 2014, again in Prague. For more details please take a look at the OOT Forum website.
