Ah, I'm sure you don't. We tests everyone's blood, just in case there's something the donor doesn't know about.
[Or are lying about to get money. But hey whatever Allen can get that]
Aggul- [Oh wait she's not a medic. He clears his throat] Well you see, many different kinds of blood have this...security system, in a sense, called antibodies. It's how it detects if something not supposed to be there, like a disease, has gotten in.
Well because of this, if the blood samples are incompatible, they'll set off those security systems...very badly. They'll start to clump together and try to destroy each other. Which if that happened in a person's veins, it'd make them very sick and might even kill them. So...better to test it in a petri dish first.
