What type of registry would maintain information about the donor and the recipient of an organ? implant registry birth defect registry trauma registry transplant registry?

The answer is transplant registry

I think the name should be self-explanatory. Implant is inserting device inside the body while transplant is giving organs. Transplant registry should record the patient that need organ and the possible donor that agree to give organ. The registry could be used to estimate the time  required for a patient to find a donor.
