LOINC Code 92844-0: FLT3 gene internal tandem dup/Normal Molgen (Bld/Tiss) [Ratio]

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/normal. 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: Molgen

What it does not mean

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

Key facts

• FLT3 gene internal tandem duplication/Normal [Ratio] in Blood or Tissue by Molecular genetics method
• FLT3 gene internal tandem duplication/normal
• This term represents a ratio (allelic ratio), following PCR amplification, of a patient's FLT3 gene DNA having internal tandem duplication to that same patient's wild type FLT3 gene DNA not having such duplication. The result is expressed as a signal ratio of peak band intensities and correlates to cells with and without mutated DNA. A ratio of 100.00 is the maximum and indicates a patient specimen has 100% FLT3-mutated tumor with no healthy cells. A ratio between 0.03 and 0.05 indicates low levels of disease.
