Understanding Your Results
Positive
EWSR1 gene fusion detected, consistent with Ewing's sarcoma. Consult an oncologist for further evaluation and treatment planning.
Negative
No EWSR1 gene fusion detected. Consider other diagnoses or repeat testing if clinical suspicion remains high.
Consult a doctor immediately if symptoms persist or worsen, or if genetic test results are positive, for appropriate management and treatment.
Limitations
- ⚠This test detects common EWSR1 gene fusions but may not identify all rare variants
- ⚠Results should be correlated with clinical and histopathological findings
- ⚠False negatives or positives can occur in rare cases
Risks & Considerations
- ●Minimal risks associated with biopsy procedure, such as infection or bleeding at the sample site
- ●Rare allergic reactions to local anesthesia
Interfering Factors
- ●Poor tissue quality or inadequate sample
- ●Improper fixation or handling of tumor tissue
