Turnaround time is dependent on the specimen load received at the TPDDL. At peak time (spring through fall), routine diagnoses are usually finished in 11-21 days, depending on the test needed for the diagnosis. Specimens requiring extensive testing require more time. For example, oak wilt testing takes a minimum of 21 days. Diagnostic results are routinely emailed to the client, but results can also be mailed. 

Please get in touch with us by email IF you have received an invoice but not the report OR have not heard anything 15 business days (3 weeks) after submission of the sample(s). We have instituted an email receipt reply notification to inform the submitter when we receive their sample and to provide a sample reference number for future inquiries related to that sample. Please make sure to check your junk mailbox.
