the Rarest Blood Type in the World

Human blood is divided into one of four main blood types (A, B, AB, and O) and are based on the presence or absence of specific antigens on red blood cells. Blood types are inherited and consist of red blood cells, white blood cells, platelets and plasma. The need for your specific type is always in need, and donors are the only source for this life saving gift.

At the point when an individual’s blood is investigated under a magnifying instrument unmistakable blood contrasts are obvious. In the mid twentieth century, an Austrian researcher named Karl Landsteiner ordered blood as per those distinctions. Landsteiner watched two particular concoction atoms present on the outside of the red platelets. He named one atom “An” and the other particle “B”.

Blood Types (Groups)

A blood type (also called a blood group) is defined as the classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). A series of related blood types constitutes a blood group system, such as the Rh or ABO system. The frequencies of the ABO and Rh blood types vary from population to population.

Blood Type A – If the red blood cell has only “A” molecules on it.
Blood Type B – If the red blood cell has only “B” molecules on it.
Blood Type AB – If the red blood cell has a mixture of both “A” & “B” molecules.
Blood Type O – If the red blood cell has neither “A” or “B” molecule.


Perhaps you realize your blood classification off the highest point of your head—or possibly you’re similar to most Americans and you do not understand. You ought to presumably discover. Here’s one reason: You could have “brilliant blood.” And while having brilliant blood may sound energizing, this staggeringly uncommon sort can possibly be fatal for individuals who have it. Find out around 8 all the more great motivations to realize your blood classification.

Every one of the basic blood classifications—A, B, AB, and O—comes in negative and positive renditions. Of these eight fundamental classifications, O positive is the most well-known, as per the Red Cross. Stomach muscle negative is recognized as the rarest blood classification in the U.S.; Healthline reports that just 0.6 percent of Americans have AB-negative blood.

While that sounds really uncommon, AB contrary has nothing on the rarest blood classification of every one of the—one that less than 50 individuals in the whole world have—which is the reason researchers have nicknamed it “brilliant blood.” The sort, whose logical name is Rhnull blood, was found in 1961. From that point forward, there have been a sum of 43 detailed cases. Its irregularity and extraordinary properties consolidate to make it possibly risky, should somebody with this sort ever need a blood transfusion. Get familiar with a few insider facts your blood classification can uncover about you.

The reason distinguishing your blood classification is so imperative is that your red platelets have receptors called antigens. On the off chance that you get a transfusion, your invulnerable framework will just acknowledge the antigens that coordinate your blood classification. On the off chance that you misunderstand the sort—and a jumbled arrangement of antigens—your safe framework will assault the platelets, with awful and possibly lethal outcomes for you. The rarest blood classification, Rhnull blood, is purported in light of the fact that it’s totally missing the most well-known sort of antigen, Rh. This implies on the off chance that you make them get, a transfusion of a blood classification with any Rh antigens will make your body dismiss the blood. Find out around 8 unsolved restorative puzzles that still stump specialists.

Since 99.9999994 percent of individuals have blood with Rh antigens, finding a blood contributor for Rhnull people can be about outlandish. This is the reason individuals who have brilliant blood are urged to give their blood on the off chance that they ever need blood, and on the grounds that others with uncommon blood classifications could profit by it. Since Rhnull blood contains no Rh antigens to be rejected, it tends to be “an all inclusive contributor for those with for the most part uncommon blood classifications,” as indicated by David Barbour, fellow benefactor of Vivio Life Sciences.

Brilliant blood, along these lines, can be both hazardous and lifesaving. And keeping in mind that your odds of having the rarest blood classification are extraordinarily low, discovering your blood classification is the best way to know without a doubt.

What if me and my donor are not a match?

If blood types are not compatible, the donor will not be able to donate directly to you. However, the donor may consider donating through a paired exchange program. Paired exchange programs allow you to get a kidney from another donor who is not a match for their intended recipient. Paired exchange involves two living donors and two recipients. If the recipient from one pair is compatible with the donor from the other pair, and vice versa– the transplant center may arrange for a “swap”–for two simultaneous transplants to take place. This allows two transplant candidates to receive organs and two donors to give organs though the original recipient/donor pairs were unable to do so with each other.

Donating Blood by Compatible Type:

The approximate distribution of blood types in the U.S. population is as follows

O-positive: 38 percent.
O-negative: 7 percent.
A-positive: 34 percent.
A-negative: 6 percent.
B-positive: 9 percent.
B-negative: 2 percent.
AB-positive: 3 percent.
AB-negative: 1 percent.
