Test Parameters & Specifications
Sample Stability
- Insufficient tissue sample
- Improperly fixed or degraded sample
- Missing clinical information or histopathology report
Understanding Your Results
Positive CDK-4 expression
Suggests overexpression, commonly seen in well-differentiated and dedifferentiated liposarcomas
Negative CDK-4 expression
May indicate absence, seen in benign lipomatous lesions, pleomorphic liposarcoma, myxoid liposarcoma, or other sarcomas
Uncertain or equivocal results
Recommend correlation with clinical history and additional tests, and consultation with a pathologist
If you experience symptoms like unexplained weight loss, persistent pain, or skin changes, or if test results are abnormal, consult an oncologist for further evaluation and treatment.
Limitations
- ⚠Test detects only CDK-4 protein, not other markers

- ⚠Results should be correlated with histopathology and clinical findings
Risks & Considerations
- ●Minimal risk associated with biopsy procedure, such as infection or bleeding
- ●No direct risks from the immunohistochemistry test itself
Interfering Factors
