Confirmatory tests for brain death have to be done twice within an interval of six hours between the tests. Once consent for organ donation has been obtained, coordinating the process of organ retrieval takes time.
Organ retrieval from deceased donors involves many hospitals , and transplant teams should ensure that the donated organs match as perfectly as possible with the recipient. If it is a medico-legal case, a post-mortem has to be performed and this involves both the police as well as the Forensic Medicine department.
