TVMDL has compiled syndrome specific diagnostic plans to assist clients in efficient diagnostic testing strategies based on clinical signs or gross necropsy findings. The client still has the ability to select the tests within the diagnostic plans that fit with the diagnostic goals and pre-test clinical suspicion of each case. Simply select the syndrome most appropriate for the case to review the testing recommendations and sampling requirements. Submit the appropriate samples and indicate which tests are desired by writing them in the “tests requested:” section of the submission form or electing them through the portal submission system. Listed tests are grouped by testing section and listed alphabetically.
