LOINC Code 51959-5: DNA region of interest Molgen Nom (Bld/Tiss)

51959-5 is a LOINC code used to identify DNA region of interest Molgen Nom (Bld/Tiss) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component DNA region of interest. It is commonly used with the system or sample type Bld/Tiss.

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component DNA region of interest. It is commonly used with the system or sample type Bld/Tiss.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation
  • Method: Molgen

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Range(s) of DNA sequence examined
DNA region of interest
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 [LOINC81293-3].
