51959-5

LOINC code 51959-5 identifies "Range(s) of DNA sequence examined". This term is used to report the region(s) of interest for sequencing studies as one or more numeric ranges that identify the parts of the reference sequence that are sequenced. These can be recorded as one or more HL7 numeric ranges using repeat delimiters to seperate multiple such ranges. They can also be recorded singly, one per OBX, using OBX-4 to distinguish these repeats with the same Observation ID. However, such detailed specification of the sequencing region of interest is rare, in part because this information is often proprietary, and the region of interest is reported as a text description instead, e.g., "Sequenced all of the coding, and appropriate flanking regions," using [LOINC: 81293-3].

This code measures DNA region of interest in Bld/Tiss. It belongs to the HL7.GENETICS class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
