But having a rare blood type is not the norm. If it was, the blood type wouldn't be "rare". I am truly sorry for what happened to your friend, but even with a biological parents information, there isn't any guarantee that they could be contacted in time or that they would still be alive or even willing to help out. You have to look at more than just what a person thinks they have a right to or are entitled to get if they are an adopted child. It's not all about their rights, but also about the rights of the person who chose to give them up, to remain anonymous. And regardless of how anyone feels about those rights, it's the reality of the world that we live in. That is why there are lawyers and agencies and contracts involved in the adoption process.
In addition, you cannot force a biological parent to be there or help out if they don't want to.
