Understanding Your Results
Positive expression
Suggests prolactin-producing tumor, common in prolactinomas.
Negative expression
Indicates absence of prolactin, may rule out certain adenomas.
High staining intensity
Correlates with active tumor growth, requiring further evaluation.
Consult a doctor if you experience persistent symptoms like infertility, headaches, or vision issues, or if test results are abnormal for further management.
Limitations
- ⚠Not for quantitative serum prolactin measurement
- ⚠Requires expert pathological interpretation
- ⚠Results may vary based on tissue quality
Risks & Considerations
- ●Minimal risks from tissue biopsy, such as infection or bleeding
- ●Results may require additional testing for confirmation
Interfering Factors
- ●Poor tissue fixation
