Conditions for Defaulting the QC Source for a Sample

Any sample created in a registration process, be it an unknown or QC sample, is assigned a QC Source of 1. Where the sample is a QC sample, then the sample is known as a registration QC sample, that is, it was registered for QC assessment for client purposes.

Any sample created for QC assessment of a parent job, that is, any QC samples created by an append/overwrite QC or QC sample maintenance process on a proposal, production, internal, template schedule or draft job, is assigned a QC Source of 2, and the sample is known as a job QC sample.

Any samples created for QC assessment of a laboratory batch job, that is, any QC samples created during a batching or QC sample maintenance process on a laboratory batch job, is assigned a QC Source of 3, and the sample is known as a laboratory QC sample. These batch QC samples belong to the laboratory/subcontract batch job—there are no links to the production jobs and samples.
