*Diagnostic reports should have better ability to reference another diagnostic report. *This was a finding from the Sync for Genes Phase 2 Pilot sites that particpated in the January 2019 Connectathon.

A molecular pathologist may have to stich together various tests/specimens. A single diagnostic report may have multiple specimens. 2 specimens may generate 2 separate results + a 3rd result referencing those 2. More help on the FHIR website for describing examples would be helpful.

HLA typing via buccal swab or blood is a relevant example. Having a GDR that can refer to other GDRs to have a separate swab for buccal swab vs blood + another that summarizes the 2 of them. Needs an advocate at O&O to push this through. Would be helpful if diagnostic reports can point to other diagnostic reports
