Planning a Clinical Sample-Processing Workflow
Define the samples, output, timing, and handoffs before starting a clinical processing program. This guide brings together the information to discuss with OrganaBio’s scientific team.
Begin with the study requirements
What arrives?
Identify the whole-blood sample type, collection volume, collection site, expected sample count, and schedule. Include protocol instructions that affect the processing workflow.
What output is needed?
Specify PBMCs, serum, plasma, and any cryopreservation requirements. Describe the PK, PD, immune-monitoring, or other downstream work the samples support.
What happens next?
Identify the downstream destination, storage needs, reporting requirements, and handoff responsibilities. Confirm these details with the scientific team as part of the program scope.
Which sites are involved?
For multiple collection sites, provide the address and timing requirements for each. Review California processing locations and the multi-site planning guide.
Describe timing precisely
Collection time, sample receipt, processing initiation, and completion are different points in the workflow. Use the interval specified by your protocol when discussing a processing window.
OrganaBio’s CPC service reports an average of 30 minutes from blood receipt to first centrifuge spin. That figure does not describe the complete collection-to-processing workflow.
Keep material requests separate
If you need donor-derived material for research, start with PBMC products or leukopaks. A clinical sample-processing request concerns the work to be performed on samples collected for your study.
For a comparison of the isolation step and the broader processing scope, read PBMC processing versus PBMC isolation.
