Is it a sign of a pending heart attack or just a message from the body telling you to exercise more, quit smoking, and watch the caffeine intake? I ask this because my best friend gets flutters and ...
Im not sure about that, its usually the other way around. I heard that type O blood is okay for everyone. This is something you shoukd ask a doctor to be sure.
no but he could give you a transfusion . O+ is a universal donor for + Rh factor .
If he has blooodtype 0, he can give to everyone, but unfortunately he can't recieve anything other than 0 himself.
No--O type is the universal donor, because it has no antigens (what causes the difference between a and b), but it does have antibodies against both types A and B. The antibodies would attack your blood and cause massive clotting in his veins. He could only receive blood from someone else who is type O+. Still, most blood banks and hospitals will allow you to give blood in his name, to help free up some of the O blood supply instead of giving it to someone else with A+ blood.
Nope, his blood would produce antigens against yours which wouldn't be safe.
No, the blood will clump together. They can only receive O+ or O-
Type O means that you don't have the A antigen or the B antigen. If someone with type O blood gets blood with A or B antigens they can get really sick or even die.
There is some evidence that the A and B blood types developed in specific geographical areas and were spread by migration. The theory is that these antigens affect how well you tolerate certain foods. It's not a widely accepted theory, but it's harmless and worth thinking about.
The + refers to something called the rhesus factor after a kind of monkey. If you don't have the rh factor, getting blood from a + can get you sick or even kill you.
no. he would have an immune response to the "A" antigen in your blood. He can only receive O- or O+ blood.
You can only donate to A+ or AB+ blood types
No. Your friend can receive only O positive or negative.
