Understanding Your Results
Mutation Detected
Presence of cKIT mutation in specified exon; may indicate aggressive tumor or targeted therapy eligibility.
No Mutation Detected
No mutations found in tested exons; further testing or alternative diagnoses may be considered.
Consult your oncologist if symptoms persist, results show mutations, or for personalized treatment planning based on test outcomes.
Limitations
- ⚠Only tests specified exons (9, 11, 13, 17)
- ⚠May not detect all cKIT mutations
