LOINC Code 48018-6: Gene studied Nom (Bld/Tiss) [ID]

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 Gene identifier. 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

What it does not mean

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

Key facts

• Gene studied [ID]
• Gene identifier
• HUGO Gene Nomenclature Committee (HGNC) identifier for a gene. List the gene(s) examined in full or in part by the study. If the study addresses multiple genes, these can be recorded in one OBX as a list seperated by repeat delimiters or in mulltiple OBX's with one gene per OBX. The recommended coding system will use the HGNC gene symbol as the display text and HGNC gene ID as the code. For example, 21497^ACAD9^HGNC.
