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.

May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
Status: ACTIVE
Order vs observation: Both
Method: Molgen

What it does not mean

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

Key facts

MECP2 gene deletion+duplication and full mutation analysis in Blood or Tissue by Molecular genetics method

MECP2 gene deletion+duplication & 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 MECP2 gene. Deletion/duplication analysis, such as by multiplex ligation probe amplification (MLPA), is also performed. This test is used for diagnosing Rett syndrome or other methyl-CpG-binding protein 2 (MeCP2)-related disorders.[GHR geneMECP2]
