Preparing pathology materials for an outside review
Understand the difference between a pathology report, slides, paraffin blocks, and molecular results before arranging an international pathology review.
Use this guide for the stage you are at. The free needs discussion does not require medical records; use your secure workspace for formal case materials.
Pathology packet checklist
Final pathology report and every addendum
Specimen and procedure dates
Biomarker, immunohistochemistry, and molecular reports
Source laboratory contact and release process
Receiving facility's written material and shipping instructions
Identify what already exists
Identify what already exists
The final report is the starting point, but outside review may require the material from which it was produced.
Collect the final report and later amendments
Match each specimen identifier to its date and procedure
List associated biomarker and molecular tests
Do not assume a PDF report replaces slides or blocks
Ask both institutions before shipping
The source laboratory controls release; the receiving laboratory controls what it can accept and how it must arrive.
Ask whether glass slides, unstained slides, or paraffin blocks are available
Obtain the receiving laboratory's exact requirements
Confirm packaging, courier, customs, tracking, cost, and return policy
Do not ship irreplaceable material to an unconfirmed address
Track custody and unresolved gaps
A written inventory reduces the risk of mismatched specimens and unclear responsibility.
Record every specimen or block identifier provided
This constructed educational example describes a plausible record gap. It does not describe a real patient or provide evidence of a clinical result.
Report available, review material not yet confirmed
Situation
An adult in the United Kingdom is exploring an oncology pathology review in China after lung surgery performed six months earlier.
Records received
The coordinator receives the operative note, initial pathology report, oncology clinic letter, and a translated case chronology.
Record gaps
A later biomarker addendum is absent. The source hospital has not confirmed which slides or blocks remain available, and no receiving-laboratory shipping instructions have been issued.
Coordination next step
The patient requests the complete report set and material inventory from the source hospital. Shipment is paused until the receiving laboratory confirms identifiers, material type, address, packaging, cost, and return arrangements.
Scope and clinical review status
This guide explains administrative preparation, not pathology interpretation. Only qualified pathology services can determine whether material is adequate or issue a diagnostic opinion.
Primary sources
The National Cancer Institute explains pathology reports and notes that second-opinion review may involve slides or paraffin blocks.
Are the pathology report and slides the same thing?
No. The report records the pathologist's findings. Slides and paraffin blocks are physical materials that an outside pathology service may request for its own review.
Should I send the original paraffin block?
Only after the source and receiving institutions confirm what is needed, whether release is permitted, and how it must be packaged, tracked, and returned.
Can a coordinator interpret my pathology report?
No. A coordinator can organize and translate records but cannot replace review by a qualified pathology professional.
Need to confirm the next step?
Discuss your needs before deciding on a paid review. If you already have a case, return to your secure workspace to confirm the specific records or arrangements with your case team.
