LOINC Code 93690-6: BRAF gene V600 mutations Molgen Nom (cfDNA)

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 BRAF gene.p.Val600 mutations. 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

• BRAF gene V600 mutations [Identifier] in Plasma cell-free DNA by Molecular genetics method Nominal
• BRAF gene.p.Val600 mutations
• Detection of BRAF V600 variants, including V600E (Val600Glu, c.1799T>A) and V600K (Val600Lys, c.1798_1799delGTinsAA), in cell-free DNA. Using cell-free DNA is alternative to invasive tissue biopsies. The most prevalent mutations are V600E (70−90%) and V600K (5−30%); other mutations are rare. A positive result indicates the presence of an activating BRAF mutation and may be useful for guiding the treatment of individuals with melanoma.
