LOINC Code 93813-4: NTRK1, NTRK2 and NTRK3 gene rearrangements Molgen Doc (Tiss)

93813-4 is a LOINC code used to identify NTRK1, NTRK2 and NTRK3 gene rearrangements Molgen Doc (Tiss) 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 NTRK1 gene & NTRK2 gene & NTRK3 gene rearrangements. It is commonly used with the system or sample type Tiss.

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 NTRK1 gene & NTRK2 gene & NTRK3 gene rearrangements. It is commonly used with the system or sample type 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

NTRK1, NTRK2 and NTRK3 gene rearrangements in Tissue by Molecular genetics method
NTRK1 gene & NTRK2 gene & NTRK3 gene rearrangements
This test detects fusions (rearrangements) involving the NTRK1, NTRK2, and NTKR3 genes to identify solid tumors that may respond to NTRK-targeted therapies. These NTRK genes rearrange with more than 80 fusion gene partners, leading to tumorigenesis across a variety of tumor types.[PMID31075511] The collection of information contained by this term may include the test method(s), targeted fusion variants, the overall result (fusion variant detected/not detected), the fusion variant identified, the interpretation, recommendations, references and clinical trial information.
