Key result
Cold stored donor platelets yield ~94% clinical consensus across platforms for light transmission aggregometry.
Why the study?
Current external quality assessment for light transmission aggregometry audits only trace interpretation, prompting investigation into whether donor platelets could assess analytical and post-analytical performance.
Population
Testing centres across England, Scotland and Wales employing Light Transmission Aggregometry
Design
Multicentre external quality assessment study

May enable reliable EQA for LTA across platforms; leaves open prospective validation before routine use.
Cold stored donor platelets can serve as stable and reliable external quality assessment material for light transmission aggregometry across different laboratory platforms.
Reilly‐Stitt et al. (2025) studied Platelet function testing. Cold stored donor platelets was evaluated on Consensus of interpretations provided by participants for agonists. Cold stored donor platelets used as external quality assessment material for light transmission aggregometry yielded a 94% to 100% consensus of clinical interpretations across different platforms.
