Because there are no antigens present on te blood cells and so the recipient cannot launch an immune response against it no matter what antibodies they express.
O blood type can be given to all other blood types because type O blood is recessive, and can be masked by other blood types.
Because they can donate to a person with any blood group.The blood group is O negative.
Type O is considered the universal blood type.
The blood type that is theoretically considered the universal donor is type O. Type O blood does not have any antigens, therefore it is compatible with any blood type.
Type O
Theres AB blood, B blood, A blood and O blood. O blood is considered a universal donnor because it has no specific code thing to it, so other blood types dont clot to it. If you mix other blood types together, you get blood clots and you can die. For example, mixing A blood with B blood will cause a blood clot. Hope this is helpful!
only o negative. any other kind will cause coagulation
Type O negative blood is a universal donor blood type. In normal circumstances, anyone can receive type O negative blood in a transfusion. When it comes to plasma donation, type AB positive is a universal donor.
Type O negative.

Type O
A person who has type O blood is called a universal donor which means you can donate blood to anybody no matter what their blood type is. The only thing is a person with o Type blood can only receive O type blood and nothing else. I worked in a ER and if the patient needed a blood transfusion and we didn't know what blood type he was we always gave type O blood.
The blood type that is can be given to anyone is blood type O-. A person that has the blood type O- is called a universal donor because O- is compatible (as long as they are not an alien!). People with negative blood types can only take negative blood types. People with positive blood types can take either positive or negative, so that is why only blood type O- is the universal blood type, not O+. :) ~Ctmusicgirl7PCH=AB
