* Angels in ''Anime/NeonGenesisEvangelion'' must be identified on the computers as having [[TechnoBabble Blood Type BLUE]] before the [[HumongousMecha Evas]] can attack them. The fact that the majority of Angels are several stories tall and [[FrickinLaserBeams shoot lasers]] isn't enough of a giveaway.
** WordOfGod is that "Blood pattern Blue!" is a shoutout to an old Japanese scifi B-movie, in which people who see UFO's have their blood turn blue (then get discriminated against). It's an in-joke. Moreover they don't actually call it "Blood type" in the sense of AB- or O+, but "Blood Wave-Pattern" which is made up technobabble.
** Like many anime series, the blood types of the main characters are listed in the supplementary materials, and fit the "blood type theory of personality" very accurately. Shinji is Type A, and is thus weak and submissive (a majority of people in Japan are actually Type A). Asuka is the only Type O, and accordingly is a hothead (it does make sense that as she is from Germany and the only non-Japanese person on the show, she has an uncommon blood type for Japan). Misato is even wounded in one episode and they display that her specific blood type she's getting in a transfusion is "AO", although there is no functional difference between "AA" and "AO" because A is dominant.

* ''ComicBook/{{Diabolik}}'' is identified as AB- in the story ''The Bird of Prey''. This is actually a plot point, as the sudden disappearance of five AB- blood donors is a clear warning that Diabolik is injured and needs blood (and, being a wanted criminal sentenced to death, going to the hospital would mean getting arrested, healed as required by the law and then executed). Ginko reacts by placing bugs on all the AB- blood donors, stopping Eva as she discovers it immediately, but it also causes a MyGodWhatHaveIDone moment when he discovers why Eva kidnapped specifically AB- donors instead of compatible people: Diabolik had been victim of radiation poisoning that could be healed only with a ''full'' transfusion, requiring as much blood as five or six persons had, with Eva not being willing to take any risk. And, being unable to kidnap more people and take the standard donation doses, Eva ''exsanguinated the five donors she had kidnapped''.

When the man needs a blood transfusion, the doctor at the black hospital proclaims that the man is O-, but, horror of horrors, the hospital doesn't have enough money to carry ''all'' blood types!

* ''Literature/{{Everworld}}'' uses this trope correctly when the main characters have to give an emergency blood transfusion to Galahad. April volunteers because she's O-, the universal donor.
* Invoked in a short story, ''Blood Money'' by Timothy O'Keefe, where a man with "a rare blood type" learns that his donation is being used by a vampire who can only digest that blood type.
* Creator/DorothyLSayers' short story ''Blood Sacrifice'' is based on another way of classifying blood types used in Britain in the early to mid twentieth century; how this translates to the modern system is unclear.

* On ''Series/{{Charmed}}'', Piper has AB negative blood as does Andy. This is shown in the episode "The Wendigo". The Wendigo also attacks people with the AB negative blood type.
-->'''Piper:''' Yeah, I'm fine. If I pass out and I need a transfusion, I'm AB negative. It's very rare. It could be a problem.\\
'''Andy:''' Uh, I was just thinking how I'm probably not the best cop to be on this stakeout with, seeing as how I'm, uh, AB negative.\\
'''Andy:''' Maybe. I've just gone over the coroners reports from Chicago, New Orleans, and now local. It turns out all the victims were AB negative.
* A third season episode of ''Series/{{Chuck}}'' features Casey [[spoiler:having to donate his AB- blood to save the life of a man he'd been trying to kill off and on for years (well, Chuck 'stole' it, but whatever)]].
* In a variant on ''Series/{{CSI}}'', a power outage shuts down the lab's equipment, and the investigators must resort to old-school ABO typing of blood evidence. Greg remarks that he's got clumping in his Type O sample; this is an error, as Type O is distinguished as such by its ''failure'' to clump when exposed to anti-A or anti-B serum. (It could've been O-positive and clumped in anti-Rh serum, but Rh-typing wasn't otherwise mentioned.)
* One episode of ''Series/DadsArmy'' was based around Pike being called up to join the regular army. The platoon can't get him out of it, so they hold a fish and chip supper to say goodbye to him - after which Pike announces that he was excused from joining the army because he has a very rare blood type, but didn't want to tell anyone until after the fish and chips.



* The title character of ''Series/{{Dexter}}'' has a AB- as his bloodtype. It's shown in flashback that [[spoiler: Dexter's foster father contacted Dexter's biological father when Dexter was injured and needed a blood transfusion, which falls into the ArtisticLicenseBiology trope since in reality Dexter could have had ''any'' negative blood type given to him and been fine.]]

* In ''Series/DeGrassi'', Holly J. only learns that she is adopted after discovering that she is type B, while both her parents are AB. She says--incorrectly--that children tend to have the same blood type as their parents, and Revelations Ensue. In fact there is absolutely nothing unlikely about two AB parents having a B child. Even if the script had been reversed--an AB child with B parents--it might only have implied that her ''father'' wasn’t who she thought.

Never mind that blood types don't actually work like this in real life (it's something to do with which factors you have and how they add together, he was far more likely to be A or B, and then positive simply because more people are positive and the positive genes are dominant, which is also why Rhesus negative women are more likely to have birth complications).

* In the ''Series/EverDecreasingCircles'' episode "A Strange Woman", Paul (Peter Egan) is taken away in a police car in the middle of the night. The following day, he explains that he is a registered blood donor and has a rare (yet unspecified) blood type and had to be rushed to the hospital to donate to an accident victim. His neighbour and self-perceived rival Martin (Richard Briers) promptly registers as a blood donor, and is disappointed to learn that he has Type O blood.
* ''Series/{{The Flash|2014}}'' plays with this in the episode Trajectory. Jesse needs an emergency blood transfusion but she has the blood type PZ-negative. Justified as she is not from this earth, she's from a different dimension, Earth-2. Luckily her father is a match.

[[spoiler:The killer's mother had died from hepatitis contracted from a blood transfusion, which slipped through the screening process; he was taking out only O- donors who could have been the source]].



* ''Series/{{House}}'' both lampshades the first and subverts the second. The subversion is something we expect from a medical show, while the lampshading comes later as House solves a case based on a patient's blood type (and a conversation with Wilson): the patient had blood type A, but when he was given a blood transfusion, was given the wrong type. Nobody ever thought to ASK him what his blood type even was to begin with. Then again, the fact that doctors do not ask patients their blood type is TruthInTelevision. ([[spoiler:In the episode, the patient's Lupus caused a blood test to give the wrong result.]]) Many people don't know, some think they know but are wrong, and very very few people know that more than the ABO/Rh factors even exist, much less what they have. And that's assuming the patient is conscious and coherent.

[[spoiler:Which is how he ends up finding out his father is not quite as dead as we thought he was]].
* The ''Series/HancocksHalfHour'' episode "The Blood Donor" is an iconic piece of British comedy.

* This is how Tommy discovers [[spoiler:that he's adopted]] in ''Series/HeroesReborn''. [[spoiler:He's AB while his mother Anne is O negative, making their relationship biologically impossible. Anne has wanted to tell him about his true parentage, but doesn't out of fear that Tommy would be captured because Tommy is an evolved human]].
* BSM Williams in ''Series/ItAintHalfHotMum'' has Type AB blood. In the episode "It's a Wise Child", this provides the Concert Party with evidence that, contrary to what Williams suspects, he is not Gunner Parkins' father, as Parkins has Type O blood.
* ''Series/{{iZombie}}'' has a slightly justified example in the first season finale when [[spoiler: Evan is caught in an explosion at Meat Cute]]. He has O Negative blood, which can only receive itself in transfusions, and the hospital is in short supply (TruthInTelevision, as O Negative is the universal donor and is used quite often). Since he needs a transfusion immediately, the only option available at the moment is [[spoiler: his sister, Liv. She refuses, however, because she's also a zombie and doesn't want to infect him]].
* Another blend of this with CriticalResearchFailure appeared on ''Series/{{Law and Order SVU}}'', when a comatose woman's mysterious pregnancy is under investigation. Her blood type is A and the fetus's is AB, so the investigators conclude that its father ''must'' be type B ... even though a type AB father would also have a 50/50 chance of passing the B trait on to his child. Particularly deserving of a YouFailGeneticsForever is Huang, who agrees that the father's type must be B despite his own medical training.
** And again on ''SVU'', they assert that two type A parents must have a type A child. In real life there is a chance they could have a type O child.



* In "Journey to Babel", an episode of ''Series/StarTrekTheOriginalSeries'', Ambassador Sarek requires open heart surgery which is hampered by his T- blood, noted as being rare, even for a Vulcan. Luckily, another person on board also had T- blood -- Sarek's son, Spock, and that had to be filtered because of Spocks [[HalfHumanHybrid human heritage]].
** And since Vulcans have copper-based rather than Humans' iron-based blood, it's realistic that it would use a different blood type system.

In ideal medical conditions, doctors do prefer to match blood type as exactly as possible, especially when doing organ transplants to reduce the risk of rejection, but in a life-or-death situation--which is the only situation this trope would find worthwhile--any compatible blood type will do. The situation of needing rare blood types is an actual problem that happens in medicine, but usually deals with other red cell antigens, most of which are rarely mentioned outside the blood banking community.

(In a sufficiently critical situation, such as when a patient is literally going through dozens or hundreds of units, even incompatible blood can be used, with compatible units reserved for the first few and last few transfusions - all the problems that would normally result from transfusing a type O patient with type A blood are negated when the patient's own blood is long gone and the type A blood is hemorrhaged out almost immediately.) The situation of needing rare blood types is an actual problem that happens in medicine, but usually deals with other red cell antigens, most of which are rarely mentioned outside the blood banking community.

* ''Series/{{The Flash}}'' plays with this in the episode Trajectory. Jesse needs an emergency blood transfusion but she has the blood type PZ-negative. Justified as she is not from this earth, she's from a different dimension, Earth-2. Luckily her father is a match.

* ''VideoGame/{{Persona Q}}'' reveals Rise Kujikawa has type AB blood. The inverse side of this trope is also Lampshaded, as the groups note the strangeness of neither the Persona 3 or 4 case having any girl with type A blood, the most common type in Japan.

* Plaid straight in the South Indian "sandalwood" film Doctor Krishna. The eponymous protagonist ex and her new husband are victims of a road accident. While Dr. Krishna's ex only has minor lacerations, her husband is in critical condition and needs AB Negative blood. Dr. Krishna is type AB- and agrees to donate. He doesn't realize that his patient needs ''three liters'' of blood just to survive. The transfusion comes dangerously close to killing him.

* Futaba Sakura in ''VideoGame/Persona5'' is AB-, which is especially notable as RH- is so rare in Japan that most works don't even list positive/negative distinction in blood types. Somewhat-fittingly, her Persona is a UFO (based on the works of Creator/HPLovecraft at that) and she's a very eccentric {{Hikikomori}}.

* In ''Series/DeGrassi'', Holly J. only learns that she is adopted after discovering that she is type B, while both her parents are AB. She says--incorrectly--that children tend to have the same blood type as their parents, and Revelations Ensue. In fact there is absolutely nothing unlikely about two AB parents having a B child. Even if the script had been reversed--an AB child with B parents--it might only have implied that her ''father'' wasn’t who she thought.
