Parent Result Link

Composite
Definition: Uniquely identifies the parent result's OBX segment related to the current order, together with the information in OBR-29 - Parent.

Usage Note: This data type is applied only to OBR-26 - Parent Result where it serves to make information available for other types of linkages (e.g., toxicology). This important information, together with the information in OBR-29 - Parent, uniquely identifies the parent result's OBX segment related to this order. The value of this OBX segment in the parent result is the organism or chemical species about which this battery reports. For example, if the current battery is an antimicrobial susceptibility, the parent results identified OBX contains a result that identifies the organism on which the susceptibility was run. This indirect linkage is preferred because the name of the organism in the parent result may undergo several preliminary values prior to finalization.
