LOINC Code 90851-7: GJB2 gene full mutation analysis Sequencing Doc (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 GJB2 gene full mutation analysis. 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: Both
• Method: Sequencing

What it does not mean

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