LOINC Code 85383-8: EGFR gene c.2369C>T actual/normal Molgen (cfDNA) [Relative 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 EGFR gene.c.2369C>T actual/normal. It is commonly used with the system or sample type Plas.cfDNA.

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

• EGFR gene c.2369C>T actual/normal in Plasma cell-free DNA by Molecular genetics method
• EGFR gene.c.2369C>T actual/normal
• The EGFR gene mutation c.2369C>T leads to a mutation that interferes with the treatment of patients with non-small cell lung cancer. The mutation is detected in the plasma as free floating cell-free DNA and is present in 50-60% of patients resistant to treatment with first and second generation tyrosine kinase inhibitors.
