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.
Yes, O positive can donate red blood cells to AB negative. O positive is a universal donor for red blood cells, meaning it can be transfused to individuals with any blood type. However, O positive donors are not universal plasma donors for AB negative recipients.
An individual who is blood type AB negative can donate blood to individuals with AB positive and negative blood types. They can receive blood from AB negative donors, as well as from donors with O negative, A negative, and B negative blood types.
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.
A person with A negative blood can donate blood to a person with A negative blood and a person with AB negative blood.
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.
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.
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.
