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.

Order vs observation: Observation
Method: Molgen

What it does not mean

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

Key facts

Chromosome rearrangement [Identifier] in Blood or Tissue by Molecular genetics method Narrative

Chromosome rearrangement

Narrative description of chromosome rearrangements identified by various molecular genetic methods. To report the result using the standardized ISCN nomenclature, use Chromosome analysis result in ISCN expression [LOINC62356-1]. To report the overall ordinal findings (e.g. Normal/Abnormal), use Chromosome analysis overall interpretation Qualitative [LOINC: 62357-9].
