The TransNet mobile application automates the organ packaging and labeling process and ensures that donated organs are matched correctly and efficiently with the identified recipient. All OPOs are required to use this application when packaging and labeling deceased donor organs, including VCA organs. You can access the Data Services Portal under UNetSM Resources to find TransNet usage rates, both by OPO and nationwide. We’ll update this information every month.

Additional details: 

When you create a case, you MUST select between a deceased or living donor.

  • a deceased donor case will function identically to prior versions.
  • a living donor case will pull donor information from TIEDI – Living donor feedback form.

Laterality validation for living donor cases only.

  • When a user selects Left Kidney, Right Kidney, Liver Split Left or Liver Split Right from the Procurement Plan screen, they will be required to enter a validators name and initials to continue.
  • This feature is important for living donor packaging and labeling because the OPO coordinators are not involved in the laterality determination during the initial work-up of the living donor.
  • No audit logs for this new feature.

Miscellaneous External Identification Label.

  • At the bottom of the Identification Labels screen, you will now see a new label.  This label is made up entirely of free text.
  • This label holds up to 27 characters per row and 6 rows max.
  • Any entered characters will persist in this new text entry box until the case is transferred or uploaded.
  • No new audit logs for this label.

“Our center began using TransNet to ensure that all organs from the outside were being checked in appropriately. Rob and his colleagues were very helpful in guiding me through all of my questions. It is easy to use, reports are easy to find and I have told several of my friends at other centers they should use it.”
