Overview
The primary purpose of the Liquid Bx Cell Free BRAF test is to detect BRAF mutations in circulating tumor DNA (ctDNA) from a blood sample. This aids in the diagnosis, prognosis, and monitoring of cancers associated with BRAF mutations, such as melanoma, colorectal carcinoma, and thyroid cancer. It is particularly useful when a tissue biopsy is not feasible or when repeated sampling is needed to monitor treatment response or resistance. The test helps oncologists select appropriate targeted therapies, such as BRAF inhibitors, and assess the effectiveness of ongoing treatment.

Understanding Your Results
BRAF V600E Mutation Detected
Positive for BRAF V600E mutation. Targeted therapy with BRAF inhibitors may be considered. Consult oncologist.
BRAF V600E Mutation Not Detected
No BRAF V600E mutation detected in the sample. Other mutations may be present. Clinical correlation advised.
BRAF V600K Mutation Detected
Positive for BRAF V600K mutation. Targeted therapy options may be discussed with oncologist.
Other BRAF Mutation Detected
A non-V600 BRAF mutation is present. Clinical significance varies; consult oncologist for interpretation.
Consult your oncologist if you have been diagnosed with a cancer that may harbor BRAF mutations, or if you are on BRAF-targeted therapy and need monitoring. Also, if you experience new or worsening symptoms, seek medical advice.
Limitations
- ⚠May not detect mutations if tumor DNA is below the limit of detection
- ⚠Results should be correlated with clinical findings
- ⚠Not a substitute for tissue biopsy in all cases
- ⚠Only detects BRAF mutations, not other genetic alterations
Risks & Considerations
- ●Minimal risk of bruising or bleeding at the puncture site
- ●Rare risk of infection
- ●Fainting or dizziness during blood draw
Interfering Factors
- ●Hemolysis or improper sample handling
- ●Insufficient blood volume
- ●Delay in processing beyond recommended time
- ●Contamination during collection
