The BE example shows that whole blood was collected from the subject, and treated with TB antigens and other assay agents. Plasma was then extracted from the the whole blood sample.

The specimen type is given in a supplemental qualifier that mimics the standard findings variable --SPEC, and draws from the 2 codelists (GENSMP and SPECTYPE) for its values, depending on whether or not the biospecimen is a sample of the subject's genetic material.

| Rows 1-5: | Give the specimen types for the 5 specimens as blood and plasma, respectively. These values come from the SPECTYPE codelist. |
