Biospecimens Tab

Field	Field Description	Permitted Values	Value Description	Study-Specific Notes
Collection ID	Identifier for the eldest sample in a lineage of processed, pooled, or aliquoted samples - typically the material actually collected from the participant. This may be the same as Parent Sample ID or Sample ID (if no processing was performed). Clicking on the Collection ID shows all samples derived from that collection.
Collection Sample Type	Type of biological material comprising the collected sample	E.g. Whole blood, Not reported, Saliva, Derived cell line
Sample ID	Unique identifier for sample, assigned by INCLUDE DCC. A sample is a unique biological material; two samples with two different IDs are biologically distinct, but may come from the same Parent Sample and Collection.
External Sample ID	Unique identifier for sample, assigned by data contributor.
Sample Type	Type of biological material comprising the sample	E.g. Plasma, White blood cells, Red blood cells, DNA, RNA, Peripheral blood mononuclear cells, CD4+ Tconv cells, NK cells, Monocytes, CD8+ T cells, B cells, Granulocytes, Treg cells
Parent Sample ID	Identifier for the direct parent from which Sample was derived, processed, pooled, etc. (if applicable)
Parent Sample Type	Type of biological material comprising the parent sample	E.g. Not Reported, Peripheral Whole Blood, Derived Cell Line, Saliva, Whole blood, WBCs
Container ID	Identifier for specific container/aliquot of sample, if applicable. Distinct aliquots of a sample will have the same Sample ID but different Container IDs.
Age At Biospecimen Collection	Age in years and days of participant at time of sample collection
Volume	Amount of sample in container
Volume Unit	Unit of sample volume
Laboratory Procedure	Procedure by which Sample was derived from Parent and/or Collection Sample	E.g. Centrifugation, RBC lysis, Lyse/fix buffer, FACS, PAXgene DNA, PAXgene RNA, Qiagen Allprep, Ficoll
Biospecimen Storage	Method by which Sample is stored	E.g. Minus 80 degrees Celsius, Liquid nitrogen storage
Sample Availability	Whether any container of the Sample is potentially available for sharing through the Virtual Biorepository	Available	Sample is potentially available to be requested through the Virtual Biorepository	Biospecimens for ABC-DS participants may be available by request from ABC-DS.

		Unavailable	Sample either was available through Virtual Biorepository but has been used up, or is part of a study that is not participating in the VBR
Container Availability	Whether this specific container is available for sharing through the Virtual Biorepository	Available	Container is potentially available to be requested through the Virtual Biorepository
		Unavailable	Container either was available through Virtual Biorepository but has been used up, or is part of a study that is not participating in the VBR
