All of our body’s cells and tissues receive oxygen from red blood cells. We need more blood – and we need it quickly if we lose a lot of it in surgery or an accident. As a result, hundreds of millions of people visit blood donation centers around the world, and thousands of vehicles bring blood bags to hospitals and processing centers.
It would be simple if we all shared the same blood type. We, on the other hand, do not. We contain up to 342 antigens molecules on the surface of each of our red blood cells that can stimulate the development of specialized proteins called antibodies. A person’s blood type is determined by the presence or absence of specific antigens.
There are negative and positive variations of each of the main blood types, A, B, AB, and O. (depending on whether or not red blood cells have a protein called an Rh antigen on their surface). According to the Red Cross, O positive is the most common of the eight primary classifications. In the United States, AB negative blood is the most uncommon blood type.
While that may sound unusual, AB negative pales in comparison to the world’s rarest blood type, which is known as “golden blood” since only about 50 people worldwide have it. Rhnull blood is the scientific name for the kind, which was identified in 1961. There have been a total of 43 recorded instances since then. Because of its rarity and peculiar qualities, it could be dangerous if someone with this type ever needed a blood transfusion. Find out what your blood type can tell you about yourself.
Your red blood cells have receptors called antigens, which is why knowing your blood type is so crucial. Your immune system will only absorb antigens that match your blood type if you have a transfusion. Your immune system will attack the blood cells if you obtain the wrong type and a mismatched collection of antigens resulting in terrible and potentially fatal effects for you.
Rhnull blood, the rarest blood type, is so named because it lacks all sorts of the most frequent type of antigen, Rh. Rhnull blood was initially identified in an Aboriginal Australian woman in 1961. Doctors had previously considered that an embryo lacking all Rh blood cell antigens would not survive, much less mature into a healthy adult. Nearly five decades later, in 2010, 43 people with Rhnull blood had been documented around the world.
Rare negative blood is in such high demand for study that, despite the anonymity of all samples held in blood banks, scientists have attempted to hunt down and approach individual donors directly to request blood.
Its life-saving potential is great because Rhnull blood can be called “universal” blood for anyone with unusual blood types within the Rh system. As a result, doctors hold it in high regard – though it will only be provided to patients in extreme circumstances and after great thought, as it may be nearly difficult to replace.
As a result, golden blood can be both life-threatening and life-saving. While the chances of having the rarest blood type are extremely remote, knowing your blood type is the only way to be certain. Next, determine whether or not the blood-type workout is beneficial.
Knowing your blood type is a useful one even if you don’t have golden blood. Not only can knowing your blood type speed up the process of receiving a life-saving transfusion, but it also indicates that different blood types are associated to different health issues.

Very interesting. I am O negative. I though I was a universal donor
