Kaitou-Shinichi long lost twins???

[Akemi~chan]

Interesting thread.  I loved the genetics part.  I only skimmed the other pages so I don't remember if it was mentioned, but I seem to remember Ran saying that she had the same blood type as Conan.  So there really isn't any sense in saying that he is any certain type based on this.

Also, I may be wrong, but I remember seeing somewhere that his blood type was A.  I don't recall where and I can't seem to find it again though, but I think it was a scan of some sort.  I also recall Kaito's blood type being B from the same or similar source.  Kaito's is easy to remember since he has the same blood type as me.  Again, I'm not sure if those are correct.

it was hakuba's lab that did it and he stated it to him and aoko in the classroom too. conan's blood type was mentioned as B,aswell in the manga. i don't remember where but i know it was mentioned. maybe not twins but cousins could work

I'm under the impression Shinichi and Ran's blood type is A too... I'll look for the reference.

I'm fairly sure it's B. Could be wrong though.

Found a fansite claiming Shinichi and Ran's bloodtype is A
I will keep looking.

Found 1 other set of info which says the info is unknown, which I suppose means the info was never given. Could the info be in the official "Conan Drill" book?

Wasn't that when Conan was shot in the cave? Afterward Ran gave Conan some of her blood? Can't remember the episode/chaper number though.

That was in the Desperate Revival arc. Ran mentioned (correctly) she had the same type as Conan/Shinichi. But the blood type was never mentioned.

The nurse just says that they don't have enough of Conan's blood type, and then Ran says that they match. The type is never stated, at least not in the english manga. I don't know about the anime or the Japanese manga.

Who, when and where?

in kaito i think it's in volume one or two when hakuba first shows up. the great deatective arrives. in Detective Cona i remember seeing it in the manga but i read forget the files because i often read them online. i never have enough money to buy it weekly.

That's been said already. I think Conia was asking when Shinichi's blood type was stated.

Actually it wouldn't make sense if Conan was the B, or even A, blood type. The doctor said that there wasn't enough of Conan's blood type, so Ran had to give him some. If Conan was the A or B (or even AB) blood type, it wouldn't matter since they could have given him O type blood. But as that happened I still say that Conan has the O blood type. *secretly wishes it were true XD*

Why? Because you have type O?

Spoiler for Clash of Red and Black:

Spoiler:

In that footage of Mizunashi Rena we saw on that tape, there was a nurse shouting that they "didn't have enough AB blood," so Rena offered some. That doesn't make sense, since AB can't give to anyone but AB, and if they had an AB patient they could have given him any other type. Either the hospital was completely out of blood, something was going on with Rh antigens, or Gosho thought giving us Rena's blood type was more important than being strictly realistic. I can see him ignoring the fact that the hospital probably wouldn't be out of A and O blood in order to let us know Ran suspected Conan of being Shinichi in Desperate Revival. 

Edit: That line about needing blood was in the manga, wasn't it? I think I remember it, but it could have been an anime change.

The general transfusion practice is to try to match the blood type of the donor and the receiver before resorting to using a different compatible type. AB is the rarest of the four types so it makes sense to have lower amounts of it is stock. Also when transfusing blood plasma, the compatibilities are reversed. AB is the universal blood plasma donor while O is the universal plasma receiver.
