Frequently Asked Questions

What is an antigen?
An antigen is a protein or marker found on blood cells, and everyone has different combinations of them. 

What is antigen matching?
Every day our Reference Lab works with hospitals and physicians to match our blood donors with patients who have the same mix of antigens in their blood. 


How do I know if I have a rare blood type?
ABO blood types are one way to define “rare blood,” with different percentages making up the population (include/link to ABO population breakdown). Antigen testing is even more focused on identifying other factors in the blood.


What can I do to help?
Answer your phone when we call, because it could mean you are the match needed to help save someone’s life.
