Our blood center uses secure laptops for every mobile drive. In each one is a replicated donor database that may be up to (but no older) than 24 hours old. After each mobile the laptops are turned in and the data is updated nightly. The replicated database allows the mobile staff to perform lookup and print blood donation records. We use the LifeTrak Donor System for this. Even after medical history is performed on the potential donor, the blood donation record undergoes a secondary review. All blood donation records then go to our Record Review department for auditing after the components have been checked in. Processing may be done concurrently with auditing. It hasn't been a big issue that collections/components may have been done on ineligible donors since we have so many checks in place. Hope this helps.
