Sample Re-Analysis: Considerations for Incurred, Analytical and Pre-analytical requirements


Instructor: Edward O Connor
Product ID: 706498

  • Duration: 60 Min
Sample re-analysis can be a quagmire of decision and indecision. Incurred sample re-analysis is required in regulated labs, but resolution of disparate results can be another difficult area. Pre-analytical issues- including mislabeling or absent sample as well as analytical issues add a measure of difficulty as well. This presentation will address these issues and help formulate acceptable resolutions.

Why Should You Attend:

This presentation will illustrate common pitfalls in sample re-analysis, how to avoid and address them, ensuring that projects will have minimum risk associated with these areas and errors. Attendees will be presented with strategies either to reduce or mitigate risks associated with sample re-analysis, whether for required retest or requested retest.

Sample Re-analysis may be driven by regulatory requirements, laboratory SOPs and protocols and by Sponsors requests. To lessen the impact on the labs, clearly described instruction and directives must be in existence before the incident occurs. Thes include SOPS covering incurred sample analysis-and describe which samples (Dose-timepoint) should be include, what the acceptance criteria is and how failures should be investigated and reported.

Routine re-analysis that is failures due to an individual sample not meeting prescribed precision requirements or due to an assay failure must also be described clearly.

Lastly, the re-analysis of sample which meet acceptance criteria as a sample and as part of an assay must be definitively prescribed. This case should be removed from the laboratory and should only be driven and attributed to the sponsor. Labs must not re-analyze samples simply because the result does not “look right”.

This presentation will provide strategies and instructions to deal with each of the cases for sample re-analysis, and which will reduce the risk of failure for each case.
