Laboratory Policy

We hope that we can be of service to you. We welcome this opportunity to explain how the Diagnostic Laboratory operates.

  • Any samples, specimens and carcasses submitted for testing become the property of LADDL and will not be returned to the client unless specific arrangements are made and approved by the lab director or designee.
  • All samples and accompanying documentation may be tested as part of a state or federal surveillance program, utilized for research and educational purposes, and/or development of new assays.
  • The LADDL strongly suggests working with your veterinarian to submit any samples. Your veterinarian is uniquely qualified to interpret laboratory findings.
  • We do not advise clients about treatment of disease. Our specialized training and experience is in diagnostics. Your local veterinarian is the best source for treatment information.
  • We charge fees for our services to fund the purchase of supplies and materials that are essential for the operation of the laboratory. Submissions are subject to an accession fee.
  • We are required by state law to report positive findings for several diseases to the State Veterinarian. For more information on reportable diseases, refer to the Louisiana Department of Agriculture and Forestry.
  • LADDL will NOT accept or euthanize any live animals intended for postmortem examination and diagnostic testing, with the exception of small production poultry and small rodents. Contacting LADDL prior to submission is highly recommended. All euthanasia is humane and in accordance with AVMA guidelines.
  • The Laboratory will not accept blood or tissue from primates. We are happy to provide referral information for primate specimens, if available.
  • A carcass submitted without the submission form or indication of the purpose of the submission will not be held more than 72 business hours. After that, the client will be notified and the carcass will be disposed. The client will be billed for disposal.

We appreciate your business. Please call 225-578-9777 if you have any questions or concerns.
