Histopathology

We perform complete margins evaluation on every biopsy specimen. The number of slides required to do this is directly related to the size of the specimen. Therefore, the costs increase with increasing specimen size.

The following guidelines are provided to assist you in correctly estimating biopsy charges for clients:

  • Measure the biopsy specimen at the greatest dimension. Specimens less than 2 cm are $80.00; if between 2 cm and 5 cm the charge is $88.00. For every additional 2 cm in size add an additional $29.00. When multiple biopsies of different sites are submitted use the largest specimen to calculate the cost of the first site.
EXCEPTION: Mandibulectomies, maxillectomies, and limb amputations are all charged $127.00 regardless of size.
  • Additional sites: Each additional site is charged at a lesser rate. Measure the size of the specimen. The charge is $34.00 for additional site and $29.00 for each 2 cm in size on sites over 2 cm.
  • Skin biopsies from the same animal are considered one site and are $80.00. This does not apply to multiple skin masses (see #1).
  • Biopsies of the gastrointestinal tract are charged separately for each site. For example: Endoscopic biopsies of stomach, small intestine, and colon would be charged as $80.00 for the first site plus $34.00 + $34.00 (two additional sites) = $148.00 total charge.
  • Nasal biopsies often include specimens from the right and left nasal cavities. They are considered one site and charged $78.00.

Histopathology on field necropsy specimen charges: Histopathology on field or clinic necropsy specimens is charged $78.00 for the first tissue and $22.00 for each additional tissue. There is a maximum charge of $125.00 per animal for commercial livestock.

Submission of large specimens in formalin: Specimens in containers with large volumes of formalin can leak and create hazards for package handlers. When submitting these specimens, consider allowing the specimen to fix completely before shipping.

Drain off the formalin and package the specimens in a sealed container with gauze squares soaked in formalin. There will be sufficient formalin in the gauze to keep the specimen moist during shipping. This will limit the potential for leakage.
