No, an O Positive person cannot donate to an A Negative person because the person who is Negative, or Rh Negative, will react to the Positive (Rh Positive) blood. Negative can only get Negative, Positive can get Positive or Negative.
Yes.
The positive or negative in the blood types refer to the Rh factor, which is an antigen. Antigens trigger immune responses. Being positive or negative for the Rh factor will impact who you can receive a blood donation from, and who you can donate blood to.
Rh factor is a protein that is found in the blood of about 85% of the population. Those who have the factor are Rh positive, while those who don't, are Rh negative. A person who is Rh negative can safely donate blood to persons with or without the protein. A person who is Rh positive can only donate to those who are Rh positive.
No although type O can donate to anyone the positive (plus) can not be put into a blood with negative. This would cause blood clumping and would be very bad.
A person with A negative blood can donate blood to a person with A negative blood and a person with AB negative blood.
If you have type o negative then you are the universal donor and could donate to any other blood type. If you have o positive then you would be limited in what blood types you could donate to.
Blood type AB can only donate to another AB type. Blood type O+ can be given to anyone, but a blood type like A or B or AB can only be donated to a person who has the same exact blood type as the person who is donating their blood.
Yes, you can't donate 0 positive blood to AB negative. The rest is possible :) RV
Blood type B positive means that you have anti-A antibodies, B-antigens, and an Rh factor that is positive. As a B+, you can receive blood from people with blood types O postive, O negative, B positive, and B negative, however a B+ blood type can only donate to a person with B+ and AB+ blood type.
No
Yes, platelets are generally type specific. In O positive, there could be an anti B Negative antigen.
People with A Positive blood can only donate to people with blood types A or AB, not any other. You can donate to people outside your blood type group, though only to AB People.
