Tissue samples submitted by referring veterinarians will be evaluated microscopically by faculty veterinary pathologists with the assistance of residents (veterinarians training to be pathologists).
- The fee for a biopsy is $65 this includes:
- Routine H&E processing
- Special stains (for bacteria, fungi etc), if needed
- Margin evaluation, if requested
- Please check the box ‘Yes’ that you would like the margins evaluated
- Decalcification of bone, as needed
- Multiple samples from a single animal
- "Necropsy in a bottle" submissions are accepted through this service
- Microscopic descriptions and interpretations of lesions are typically reported within 72 hours.
- Results are reported by an automated fax
- If a fax machine is not available, results can be sent via U.S. Postal Service or e-mail
- Samples of bone, particularly digits and jaws with teeth, can take an extended period of time for decalcification, which will result in a substantial delay in reporting results (up to 2 weeks or more in some cases)
- If special stains or consultations with other pathologists are required, these additional steps may result in a delay in reporting results
- Sample handling
- Tissue samples should be placed in 10% neutral buffered formalin with at formalin to tissue ratio of 10:1
- Please do not try to formalin –fix large samples (spleen, limbs), just refrigerate them and have them delivered promptly to UT
- Please use only screw-top lids to avoid formalin spillage during transport
- Please do not use glass containers (to minimize the risk of breakage during transport)
- Please place the completed paperwork in a plastic bag to protect it in case of spillage during transport
- Samples can be mailed to UT, picked up by FedEx or the UT courier service (insert links)
- For examination of surgical excision (margins) we recommend:
- Painting the excisional margins with surgical marking dye prior to fixation
- For larger skin masses (>3 cm diameter), partial transection from the skin side into the specimen approximately ¾ of the way through the sample (toward the deep margin) to improve fixation
- Marking the orientation of at least one margin (e.g. cranial, caudal, right or left lateral) by suture placement
Slide Consultation Service
Slide Consultation Service is offered for those cases in which a second opinion is desired. We recommend submission of 6 unstained slides. The biopsy submission form should still be filled out completely (insert link). These cases are always reviewed by multiple faculty veterinary pathologists.
Immunohistochemistry service is offered for those cases in which more specific characterization of a lesion is desired. In most cases, immunohistochemistry is performed in-house, but in some cases they may be sent out to other specialty laboratories.
- The typical cost of these procedures is $45 for each antibody used.
- Charges for immunohistochemistry sent out to other laboratories may differ.
