Less than one percent of people in the world have AB Negative blood, making it one of the rarest blood types in the world. Over the years, TV show writers have used their (often limited) knowledge of this blood type as a pivotal plot point. For example, over the course of "The A-Team," we learn that both B.A. and Murdock have this blood type. From comedies to crime dramas, here are some shows that feature characters with AB Negative blood.
In the vampire episode with the cheeky title "The Episode Sucks," a villain targets people with O- blood (the blood type of so-called universal donors) because he needs blood transfusions. Eventually, Detective Lassiter is targeted, but Gus and Shawn save the day. You know, after they spend the majority of the episode convinced that a real-life vampire, and not a sick criminal, is what has been hunting poor Lassie. Also great fun: watching Shawn and Gus dress as a famous movie vampires while on their "stake out."
In one of the most memorable episodes of "Dexter," we see a flashback where young Dexter is injured and needs a blood transfusion. Harry calls in Dexter's actual father in order to get the blood, since Dexter and his biological father share the same AB Negative blood type. Dexter writes his mystery donor a thank you card, which his father holds on to for years. Sadly, he doesn't play much of a part in Dexter's life, and Dexter's brother Brian kills him off before Dexter gets a chance to know him.
On one memorable episode of "Charmed," we learn that both Piper and Andy have this blood type. Unfortunately, the reason it comes up is because the Wendigo is hunting down and killing people with AB Negative blood.
It makes sense that a show that takes place in a hospital would do a few episodes relating to blood type, and AB blood has been the subject of conversation on several occasions. In one episode, a patient's lupus causes a blood test to give the wrong result, while in another episode a woman who needs a new liver is at a disadvantage because of her AB- blood type.
In the second season finale of this Tony Shaloub dramedy, there's a character who proclaims that he has "AB-negative with a D-antigen-the rarest blood-type in the world!" He's right, in a way. It's rare because it doesn't exist. Just goes to show you how well the average TV writer does their research before putting pen to paper.
