False<\/strong>.<\/p>\n\n\n\n<p>Persons with type AB blood are not universal donors; they are actually known as <strong>universal recipients<\/strong> when it comes to blood transfusions. To understand this, let&#8217;s delve into blood typing and transfusion compatibility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Blood Typing and Antigens<\/h3>\n\n\n\n<p>Blood type is determined by the presence or absence of specific antigens (proteins) on the surface of red blood cells. The four main blood types are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A<\/strong>: Has A antigens on red blood cells and anti-B antibodies in the plasma.<\/li>\n\n\n\n<li><strong>B<\/strong>: Has B antigens on red blood cells and anti-A antibodies in the plasma.<\/li>\n\n\n\n<li><strong>AB<\/strong>: Has both A and B antigens on red blood cells but no anti-A or anti-B antibodies.<\/li>\n\n\n\n<li><strong>O<\/strong>: Has no A or B antigens but both anti-A and anti-B antibodies.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Universal Donor vs. Universal Recipient<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Type O-negative<\/strong> is known as the universal donor for red blood cells. This is because type O-negative blood has no A or B antigens, which means it will not trigger an immune response in recipients of any blood type. Therefore, O-negative blood can be safely given to patients with any blood type in emergencies.<\/li>\n\n\n\n<li><strong>Type AB-positive<\/strong>, on the other hand, is considered the universal recipient for red blood cells. People with AB blood have both A and B antigens, meaning they do not produce antibodies against either antigen. As a result, they can receive blood from any ABO type (A, B, AB, or O).<\/li>\n<\/ul>\n\n\n\n<p>However, when considering <strong>plasma donations<\/strong>, AB blood type is considered the <strong>universal donor<\/strong> for plasma. This is because type AB plasma does not contain anti-A or anti-B antibodies, making it compatible for transfusion to individuals of any ABO blood type.<\/p>\n\n\n\n<p>In summary, persons with type AB blood are universal recipients for red blood cells but universal donors for plasma.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Persons with type AB blood are sometimes called universal donors.
