Guidelines for Sample Submission
Formalin Fixed samples
- Please ensure that the sample is fully immersed in formalin (appropriate ratio for size of tissue sample to volume of formalin is 1:10).
- If various lesions from different anatomical locations are submitted, collect the sample in separate containers.
- Label container(s) with patient name, sample source, and location.
- Double ziplock-bag the containers and place a paper towel or other absorbent matierial in the first bag, in case of leakage.
- If considering sending fresh samples, contact the Pathology office before shipping.
- Fresh samples must be shipped via priority overnight shipping (FedEx overnight express).
- Only ship fresh samples Monday - Thursday, as we do not receive packages on weekends.
- Wrap the tissue sample in saline-soaked surgical gauze (excess fluid should be gently squeezed out). Place tissue with gauze in a tightly sealed container, such as a pill bottle or zip-lock bag, to prevent dessication.
- Place the wrapped sample with some gel cooling packs in a styrofoam box. Ensure that the sample and cooling packs are separated by some paper towels to avoid freezing of sample during shipping.
- Indicate the origin of the tissue sample, especially if they come from multiple sites.
- Ensure the fresh tissue samples are kept separate from formalin-fixed tissues; eg: different bag.
Submission of clinical images
- Hard copies: Submission of clinical pictures is highly appreciated. Add hard copies with the submission form and sample.
- Email attachments: Images can be email to firstname.lastname@example.org. Please clearly state the animal's name, owner's name, and clinic name in your email.
- Complete this electronic Biopsy Submission Form and when you get to the “Mandatory Special Review” section, select “Dermpath”, which will open up a “Veterinary Dermatology specific form”. Please thoroughly complete both of these forms and send a hard copy of the “Derm form” with the wet tissue sample in a second plastic bag.
- Add some padding and absorbent towels before placing specimen in FedEx envelope or priority mail box. Ensure package is crush-proof and will withstand typical shipping conditions.
