Sample form and instructions effective January 2022

Turnaround time

Generally 5-7 working days from receipt of the sample. Turnaround time varies from 5-21 days depending on the requested test (see sample submissions form) and does not include the time necessary for shipping.

Test Cancelation Policy

Cancellation of a test request must be made within 24 hours of receipt of sample and before specimen testing has started. We regret that a cancellation request received after testing has started or after the test result has been reported cannot be honored.

Adding a Test on the Same Specimen

Provided that an adequate quantity of a specimen is available, additional tests may be requested on a specimen within one month of specimen receipt. Each additional request will be billed to the appropriate party. Any additions to samples submitted via Antech, Idexx, or other reference laboratory must be made by the submitting laboratory.
