Discovery of unique blood type stuns scientists

French scientists have identified a brand new, super rare blood type called "Gwada negative" in a woman from Guadeloupe.
It's only the 48th blood group system ever discovered and comes from a unique genetic mutation.
This could make life easier for people who struggle to find compatible blood matches.

TL;DR

Uncovering the mystery of the rare blood type

The journey started back in 2011, when doctors noticed something unusual during routine tests before surgery.
It took until 2019—and some advanced DNA tech—to confirm the rare mutation.
Finding new blood types like this means better transfusions and care for folks with uncommon blood groups.

Search for more 'Gwada negative' individuals

The French Blood Establishment is now hoping to find others with Gwada negative, especially among donors in Guadeloupe.
More donors could mean safer treatments and less stress for anyone with this ultra-rare blood type.
