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 CASR 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

CASR gene full mutation analysis in Blood or Tissue by Sequencing

CASR gene full mutation analysis

Full sequencing analysis of all 6 coding exons and intron/exon boundaries of the CASR gene is performed to establish a diagnosis of familial hypocalciuric hypercalcemia, neonatal severe primary hyperparathyroidism, or autosomal dominant hypoparathyroidism.[NCBI Gene ID846] This test is also performed as part of a workup for primary hyperparathyroidism, idiopathic hypoparathyroidism, and Bartter syndrome.[OMIM: 601199]
