I used this program to track stem cell donors in my database. It was easy to use with many features that were helpful when trying to match people who had compatible HLA types. This product is great if you are looking to find potential matches or even just keep your current ones organized! There isn't much out there like it. When we first started using it, things seemed complicated at first but now its very user friendly. We have found a lot of success by being able to easily pull up all information about each donor so we can make sure they stay active within our system.
