Schema Version 3.36
Description The biological sample template is a legacy template that defines and annotates the types of samples derived from study subjects and when during the study schedule the sample was derived. The function of this template is also captured in the experiment samples template. This template will continue to be supported for the foreseeable future to support backward compatibility.
Template ColumnRequiredDescription
User Defined ID True The biological sample user defined ID is an identifier chosen by the data provider to refer to a sample. This ID may be referenced by other data records (e.g. experiment sample). The user defined ID is not shared.
Type True The sample types are adopted from Uberon, Cell and CHEBI ontologies.
Subtype False Enter a sample type that is of finer resolution than the standard sample types provided. If the 'Biological Sample Type' is 'Other', then the sample subtype must be entered.
Name False The biological sample name is not referenced by other data records.
Description False The biological sample description is used to describe details of the sample not captured in other columns.
Subject ID True Please enter either a subject user defined ID or ImmPort accession for the subject from which the sample was derived. A single subject record is permitted.
Study ID True A biological sample may be linked to a single study.
Planned Visit ID True The link to a study's planned visit provides temporal context for a sample's derivation from a subject.
Treatment ID(s) False Please enter either a treatment user defined ID or ImmPort accession if the sample was manipulated in a manner significant to the assay prior to the assay being conducted. One or more identifiers can be entered per sample. Separate identifiers by semicolon (;).
Study Time Collected True Study time collected describes the time value for when a sample was derived from a subject.
Study Time Collected Unit True The time units are standard terms recommended by the HIPC Standards group.
Study Time T0 Event True The time zero event refers to the study milestone upon which time is based.
Study Time T0 Event Specify False Enter a time zero event if 'Other' is selected in column 'Study Time T0 Event'.
