The EXIMIOUS SOP tool is a collection of protocols which describe the collection, storage and shipment of biological samples for analysis of internal exposome markers.

EXIMIOUS involves collection of large amount of data, including biological samples, for the characterization of external and internal exposome markers. Samples are collected, stored and shipped at different sample collection and involves many different centers/ partner organisations. Several sample collection sites pose additional challenges such as mines and factories, and we also sampled patients in hospitals. In these complex projects, it is of crucial importance that a common, evidence-based and harmonized protocol is drafted and applied.

The EXIMIOUS SOP protocols describe the steps involved in sample collection, processing, storage and shipment. Critical steps are highlighted to assure the sample quality, which in our project was ensured by collecting and assessing sample quality of pilot samples before finalizing the SOP.
