Requesting Tissue Blocks and Slides for Second Opinion
Can I get my actual tissue blocks and slides sent to another pathologist for a second opinion?
Yes, contact the original hospital's pathology department (not HIM) and submit a written request specifying where to send the materials. Labs must retain tissue blocks and slides for at least 10 years, and second opinion pathology changes the diagnosis or treatment plan in up to 10% of cancer cases.
Unlike most medical records, pathology has a unique physical component: the tissue itself. Preserved in paraffin wax blocks with glass slides, these are the physical evidence of your diagnosis—and you have the right to have them reviewed by another expert.
Why You Might Need Your Blocks and Slides
The primary reason to request your pathology materials is to obtain a second opinion. While pathology is a rigorous science, there can be interpretive differences between pathologists, especially in rare or complex cases.
Benefits of a Second Opinion:
Your Right to Physical Specimens
Your right to have pathology materials sent for a second opinion is well-established and protected. While the physical blocks and slides are property of the originating institution, you have a right to have them reviewed by a consultant of your choice. The provider cannot deny your request.
| Specimen Type | Typical Retention Period |
|---|---|
| Paraffin Blocks | 10 years or more |
| Glass Slides | 10 years or more |
| Pathology Reports | At least 10 years, often permanently |
Good News: These retention periods mean that even if your diagnosis was several years ago, the physical evidence should still be available for review.
The Process for Requesting Your Materials
- 1.Identify the Second Opinion Institution
Decide where you want materials sent—typically a large academic medical center or cancer center with expertise in your condition. Your oncologist can usually recommend one.
- 2.Contact the Second Opinion Institution
Contact their pathology department. They will provide their address and any required forms for incoming consultations.
- 3.Make the Request to the Original Institution
Contact the HIM or Medical Records department where your biopsy was processed. Submit a formal written request including your name, DOB, procedure date, and the receiving institution's full address.
- 4.Follow Up and Expect Fees
The process typically takes 1-2 weeks. The original lab may charge a fee for retrieval and shipping. Follow up with both institutions to confirm receipt.
