    Ok this is just flat wrong. And dangerous. People with Type O + blood have NO ANTIBODIES IN THEIR BLOOD ASIDE FROM THE RHESUS PROTEIN. The O basically stands for zero or null. They can only receive blood from people with O+ or O- blood. That’s it. However the can donate to A+, B+, AB+, and O+.
    You basically got AB+ and O+ mixed up.

      It actually means there are no A or B antigens on the surface of our red blood cells, but we have both A and B in the plasma. This is why O negative donors are univeral blood donors, but AB donors are universal plasma donors, as they have no antibodies in their plasma. Someone with O blood can only give plasma to other type o’s. O positive blood can be given to anyone who is rhesus positive, as there are no A or B antigens on the red blood cells, but there is the rhesus factor. O negative can be given to any blood type as there is no rhesus factor or antibodies on the surface of the red blood cells.
