Discussion of SET(Specimen Event Tracking) Profile We discussed LBL supplement in Tokyo meeting last year. Two new optional transactions was suggested. 1st event “labels & containers delivered” was added in LBL profile. 2nd event "Specimens collected" should not be part of this profile. This event exists in LTW between Order Placer and Order Filler. However it is not described explicitly enough. Specimen Event Tracking (SET) actor: “Specimen Event Informer” & “Specimen Event Tracker” Background

Point of issue  Which field should be assigned in HL7 message. especially the patient status before blood collecting.
