LOINC Code 85100-6: FLT3 gene internal tandem dup Molgen Ql (BM)

85100-6 is a LOINC code used to identify FLT3 gene internal tandem dup Molgen Ql (BM) in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component FLT3 gene internal tandem duplication. It is commonly used with the system or sample type Bone mar.

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 FLT3 gene internal tandem duplication. It is commonly used with the system or sample type Bone mar.

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: Molgen

What it does not mean

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

Key facts

  • FLT3 gene internal tandem duplication [Presence] in Bone marrow by Molecular genetics method
  • FLT3 gene internal tandem duplication
  • Detection of an FLT3 internal tandem duplication (ITD) mutation in bone marrow for the diagnosis of acute myeloid leukemia (AML). The FLT3 wild type alleles produce a fragment that is approximately 327 +/-1 base pair (bp), while alleles containing an ITD mutation will produces a fragment that is approximately >=330 bp.
