What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

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 NAGLU 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.

Key facts

NAGLU gene full mutation analysis in Blood or Tissue by Sequencing

NAGLU gene full mutation analysis

Full sequence analysis is performed to test for the presence of a mutation in all coding regions and intron/exon boundaries of the NAGLU gene to confirm a diagnosis of mucopolysaccharidosis type IIIB. Testing may also be performed on at-risk family members when there is a family history of mucopolysaccharidosis type IIIB but a disease-causing mutation has not been previously identified.[GHR geneNAGLU]
