The 0.00000625% Rarity: Is the "Aurum Blood" from Netflix’s "My Dearest Assassin" actually real? 🩸✨
If you’ve started watching the new Thai thriller My Dearest Assassin on Netflix, you were likely struck by the opening claim: a blood type so rare it’s shared by only a handful of people on Earth.
It sounds like a classic "MacGuffin"—a fictional device used to drive a high-stakes manhunt. But as we’ve seen with the science of memory in Citadel, sometimes the most "sci-fi" elements on screen are grounded in a hidden reality.
The Real Science of "Golden Blood":
- Beyond A, B, and O: While we are taught there are only 8 blood types, there are actually over 50 Rh antigens.
- The Rh-null Phenotype: In 1961, doctors identified the first case of "Golden Blood"—individuals who lack every single antigen in the Rh system.
- A Global Total of ~50: In the real world, only about 50 people have been identified with this blood type. The movie calls it "Aurum Blood" (from the Latin for Gold), and its rarity makes these individuals the ultimate "Universal Donors"—and the ultimate targets.
We’ve looked into the hematology behind the thriller to see where the movie sticks to the facts and where it heightens the drama for the screen. It turns out that being "precious" in a world of supply and demand is a dangerous thing.
