93813-4

LOINC code 93813-4 identifies "NTRK1, NTRK2 and NTRK3 gene rearrangements in Tissue by Molecular genetics method". 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.[PMID: 31075511] 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.

This code measures NTRK1 gene & NTRK2 gene & NTRK3 gene rearrangements in Tiss. It belongs to the MOLPATH.PHARMG class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
