Submission Forms and Instructions

We will have a skeleton crew at the TPDDL during the week of August 7-11 due to many participating at the Annual American Phytopathological Meeting & Annual TNLA Expo. Our services will be limited and potentially delayed during this period. We recommend limiting or delaying sample submissions from Friday, August 4 – Friday, August 11 to ensure that we have the freshest specimen for analysis. Thank you for your patience and we apologize for any inconvenience this may cause!

All downloadable forms are in pdf format. You may need to get Adobe Acrobat Reader (free reader) to be able to access these forms. These are fillable pdf forms.


Unless sample submission is FOR A SPECIFIC TEST (as noted on the form), you should complete FORM D1178 – General Diagnostic Service Form.

For specific test that does not have a specified form, please use FORM D1178 РGeneral Diagnostic Service Form and note the requested test in the SPECIFIC TEST REQUEST (bottom right corner of form) area.  Specific requested testing may incur additional charges.
