Yes.
If he or she left some traces then yes it would help.
You COULD, but traces of the drug would be transferred over to the donated blood. I don't know if the donated blood is tested for it, but the medical personnel doing the collecting would definitely be told to watch out for donors like that, and to turn them away.
In a normal urinalysis, you would expect to find clear urine, no traces of blood, normal levels of protein, glucose, ketones, and pH, and no presence of bacteria or white blood cells.
they would because its not their own blood and they are not yet used to the new blood
Blood is a collective uncountable term, but in the sense of tribes or tribal members, it could be "bloods" -- but this would have very rare and specific uses.Example:The chicken coop showed traces of chicken, dog, and cougar blood. (not bloods)
If blood wouldn't clot then when someone got a cut his blood would never stop leaking from it. Now that the blood does clot the hole will be filled up and the blood would stop.
Someone with schizophrenia who wasn't taking medication would have the same blood pressure as anyone else (112/64).
Having a rare blood group (such as AB negative) would make someone a rare blood donor.
There is no best blood type. Someone who is in need of blood would probably want to be of type AB blood because that would make them what is called a "universal receiver," or one who can receive any blood type. On the other end of the spectrum, someone with type O blood is what is called a "universal donor" because their blood can be used by anyone of any blood type safely.
No.
No. You would have to be a O blood type. That is the "universal" blood donor. The best kind.
