Test Parameters & Specifications
Sample Stability
- Insufficient or poorly preserved sample
- Missing clinical information or histopathology report
- Sample not in required fixative
Understanding Your Results
Positive
Presence of CD79a protein confirms B-cell lineage, strongly suggestive of B-cell lymphoma or related disorder.
Negative
Absence of CD79a protein may indicate non-B-cell origin, requiring further testing for accurate diagnosis.
If you experience symptoms like swollen lymph nodes, unexplained weight loss, or night sweats, consult an oncologist promptly for evaluation and possible CD79a testing.
Limitations
- ⚠Cannot determine lymphoma subtype alone; requires additional tests
- ⚠Requires biopsy tissue; not applicable for blood samples
- ⚠Results may vary based on tissue quality and processing
Risks & Considerations
- ●Minimal risk from IHC testing itself
- ●Biopsy-related risks such as bleeding, infection, or discomfort at the collection site
Interfering Factors
- ●Improper tissue fixation
- ●Technical errors in staining procedures
- ●Sample degradation during transport
