When a tech determines that we cannot run the LDL DIRECT here at CMMC:
--cancel it
--order LDL D ARUP (ARUP test code #20257) on the same accession number but a different container
--place sample in ARUP refrigerated box

LDL D ARUP is not orderable in CERNER and is not to be the primary ordered test

ARUP #20257: sample (serum heparinized plasma) is good for 5 days refrigerated
