World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonization Project: III. Fluid biospecimen collection, processing, and storage in endometriosis research
2014
Objective To harmonize
standard operating procedures(SOPs) and standardize the recording of associated data for collection, processing, and storage of fluid
biospecimensrelevant to
endometriosis. Design An international collaboration involving 34 clinical/academic centers and 3 industry collaborators from 16 countries on 5 continents. Setting In 2013, 2 workshops were conducted, followed by global consultation, bringing together 54 leaders in
endometriosisresearch and sample processing worldwide. Patient(s) None. Intervention(s) Consensus SOPs were based on: [1] systematic comparison of SOPs from 18 global centers collecting fluid samples from women with and without
endometriosison a medium/large scale (publication on >100 cases), [2] literature evidence where available, or consultation with laboratory experts otherwise, and [3] several global consultation rounds. Main Outcome Measure(s) Standard recommended and minimum required SOPs for biofluid collection, processing, and storage in
endometriosisresearch. Result(s) We developed recommended standard and minimum required SOPs for the collection, processing, and storage of
plasma,
serum, saliva, urine, endometrial/
peritoneal fluid, and menstrual effluent, and a
biospecimendata-collection form necessary for interpretation of sample-derived results. Conclusion(s) The
Endometriosis
Phenomeand
BiobankingHarmonisation Project SOPs allow
endometriosisresearch centers to decrease variability in biofluid sample results, facilitating between-center comparisons and collaborations. The procedures are also relevant to research into other female conditions involving biofluid samples subject to cyclic reproductive influences. The consensus SOPs are based on the best available evidence; areas with limited evidence are identified as requiring further pilot studies. The SOPs will be reviewed based on investigator feedback, and through systematic tri-annual follow-up. Updated versions will be made available at: endometriosisfoundation.org/ephect.
