WELCOME TO THE TRUE BLOOD GROUP!
A community for exploring Rh-negative blood, genetics, ancestry, history, science, mysteries, and the questions that still remain.
We share research, personal experiences, historical discoveries, theories, and plenty of interesting conversations.
Some topics are established science. Others are theories worth exploring. Stay curious, question everything, and respect each other.
Our website features independent research articles, blood-donation resources, and the True Blood Group shop. We’ll continue expanding the research side with new articles, deeper investigations, and new topics to explore.
What first made you curious about your blood type?
