Overview
The purpose of the Review of 7-9 Slide and Block test is to provide an expert second opinion on previously prepared histopathology specimens. This review helps confirm or revise an existing diagnosis, identify the need for additional ancillary testing such as immunohistochemistry or molecular studies, and ensure diagnostic accuracy before treatment decisions are made. It is especially valuable for complex cases, rare tumors, and situations where there is diagnostic uncertainty or discrepancy between clinical findings and the original pathology report.

Doctor's Notes
Reviewed by Dr Pasupathy Arumugam — MBBS, MD (Pathology) · Reg. No. 21521
"A histopathology review of slides and blocks is an essential step in ensuring diagnostic accuracy, particularly in cancer care. When patients seek a second opinion, transfer care between institutions, or when the initial diagnosis is uncertain, having an experienced pathologist re-examine the original specimens can confirm, refine, or revise the diagnosis. I routinely recommend this review for patients with complex or ambiguous histopathological findings before initiating any treatment protocol. Accurate pathology is the foundation of effective treatment planning."

Test Parameters & Specifications

- Unlabelled slides or blocks without patient identification
- Damaged, broken, or fragmented slides
- Missing clinical details or requisition form
- Slides with excessive fading, contamination, or poor staining quality
- Mismatch between submitted slides and blocks or between labels and requisition form
Understanding Your Results
The reviewed tissue shows no evidence of malignancy. The original benign diagnosis is confirmed. Routine follow-up as advised by your physician is recommended.
The reviewed tissue confirms the presence of malignant cells. Tumor type, grade, and other relevant features may be further specified. Consult your treating oncologist to discuss treatment options.
The tissue shows atypical features that are suspicious but not definitively diagnostic of malignancy. Additional ancillary testing such as immunohistochemistry or molecular studies may be recommended.
The findings are inconclusive based on the available slides and blocks. Additional tissue sampling, repeat biopsy, or ancillary testing may be required for a definitive diagnosis.
The review has identified a diagnosis different from the original report. Your treating physician should be consulted to discuss the implications of the revised diagnosis for your treatment plan.
Consult your doctor if the review report indicates a revised or new diagnosis, recommends additional testing such as immunohistochemistry or molecular studies, reveals malignant findings not previously identified, or if you have any questions about the findings and their implications for your treatment plan.
Limitations
- ⚠Review is limited to the tissue available on the submitted slides and blocks
- ⚠Additional ancillary testing such as immunohistochemistry or molecular studies may be recommended but is not included in this review
- ⚠Diagnosis may be deferred if tissue quality or quantity is insufficient
- ⚠Original staining quality may limit the scope of interpretation
- ⚠This review does not replace a fresh biopsy when clinically indicated
Risks & Considerations
- ●No physical risks to the patient as this is a non-invasive review of existing specimens
- ●A revised diagnosis may require changes to the current treatment plan
- ●Additional testing may be recommended based on review findings, which may involve additional cost and time
Interfering Factors
- ●Poor initial tissue processing or fixation may affect interpretation
- ●Inadequate or faded staining on submitted slides
- ●Tissue drying artifacts or crush artifacts from original biopsy procedure
- ●Insufficient tissue on submitted slides for definitive assessment
- ●Mismatch between submitted slides and blocks

|---|---|---|---|---|---|
| Comparison | Review of 7-9 Slide and Block | Involves review of fewer slides and blocks; suitable for single biopsy specimens or focused second opinions on a limited number of slides. | Involves review of a larger number of slides and blocks; suitable for complex cases with multiple biopsies, extensive surgical specimens, or cases requiring comprehensive evaluation. | Involves processing and examining new tissue from a fresh biopsy rather than reviewing existing slides; provides opportunity for additional ancillary testing on fresh tissue. | An ancillary test that uses antibodies to detect specific proteins in tissue; often recommended following a histopathology review to further characterize tumors or confirm diagnosis. |
