Come on, find out the 9 most rare blood types in the world!

Every drop of our blood contains red blood cells that carry oxygen throughout the body. Our blood also contains white blood cells that help fight infection. Then, there is also a platelet content that helps your blood clot.

Blood also contains antigens, namely proteins and sugars, which are present in red blood cells. This is what gives the blood of their ‘groups’. At least 33 blood group systems have been identified, but only 2 are widely used, namely the ABO and Rh-positive / Rh-negative blood groups only.

These two groups form 8 basic blood groups that most people know, among them A +, A-, B +, B-, AB +, AB-, O +, and O-. This is the most common blood type and is owned by many people. Continue, is the rare blood group aka only a few people have it? The answer is, yes.

Although it is difficult to sort them, because each country has different statistics, we try to sort them for you. Below are the rarest to somewhat more common blood types.

1. Rh-null

What is the rarest blood group? It is difficult to say which blood group is the rarest in the world, because they are related to genetics. That means the prevalence of certain blood groups varies widely in different parts of the world. However, there is such a thing as Rh-null. There are only 43 people in the world who have it.

Rh-null blood lacks 61 antigens that may be present in the Rh system. Uniquely, Rh-null blood can be used to help anyone, regardless of blood type and rhesus. This is why Rh-null is also called golden blood, because its value is considered the same as gold.

Unfortunately, until now only 9 people in the world are active donors. In fact, the owner of this folder can only receive from Rh-null too! So, people who have Rh-null are advised to donate blood as an investment in the future in case he or she needs it himself.

2. AB-

However, in the United States, AB negative is considered to be the rarest blood type. Stanford Medical School Blood Bank said AB-Goldar owned only 0.6% of the population. Being the rarest blood group, AB Plasma is universal and can be used for all patients regardless of their blood group. Hence, if this is your gold, please know that your blood can help many people!

3. B-

B negative is only owned by 1.5% of humans. Why is B negative blood important? Because this is one of the rarest blood types in the world. Because it is so scarce, it is difficult to find a new donor to meet the needs of B-blood stock. Who can receive B negative blood? People with blood types B and AB, either Rh positive or negative.

4. AB+

AB positive is the blood group of 3.4% of people on earth. Very rare! Where only 1:29 people have AB + blood. AB + is a universal plasma recipient and donor (compatible with all blood groups), making it a very important blood group. Usually donors will be asked for platelets and plasma, but whole blood is also accepted. However, because the owner of AB blood is a little positive, it is hoped that there will be many donors from this Goldar.

5. A-

A- owned by as many as 6.3% of people worldwide. The number is more or less similar to the owner of B-. This blood type is rare because at least one in 13 donors has it. People with Goldar A and AB (positive or negative) can accept donor A-.

That way, A negative red blood cells can be used to treat about 40% of the human population. However, people with blood A negative can only use blood A negative again and only O negative.

6. O-

Next there is the O negative Goldar. About 6.6% of people have this blood type. Type O negative blood type is much sought after because patients of all blood types can use it (in an emergency).

Unfortunately, this type of blood is quite rare, only 1 in 7 people who have O negative blood (because most people who have O positive). Ambulances and hospitals usually have O-blood supplies for emergencies. So, if you have this goldar, try to be diligent as a donor, yes, many people might need you!

7. B+

As many as 8.5% of people have blood type B +, which means that it can only be obtained from 1:13 donors. B positive can only donate for blood type B positive and AB positive only. While the blood types that can be accepted by person B positive are only B and O (be it negative or positive).

Blood type B + is very important because it can help treat sickle cell disease (sickle cell disease), which is a condition in which red blood cells are deformed and damaged. Where should the red blood cells be round, this is sickle instead, so that healthy red blood cells are lacking. This disease can trigger many other diseases, from anemia to thalassemia. Many South and Black Asians have blood type B +.

8. A+

Next, there is A+ Goldar, A positive. As many as 35.7% of people in the world have it. Goldar A is positive for A-type antigen in the presence of a protein called rhesus factor (Rh). According to the American Red Cross, this is one of the most common blood types.

Blood type A + has certain personality traits, although there is no scientific evidence that blood type is associated with any particular trait.

According to those who believe in this theory, personality traits associated with blood group A + include stubbornness, earnestness, responsibility, patience, quiet, thoughtful, and creative. You agree, don’t you?

9. O+

The last blood type is O positive. As many as 37.4% of people in the world have it, which means this blood type is the most common and widely found. In comparison, 1 in 3 blood donors must have this goldar.

Who can receive O positive blood? Anyone with blood type is Rh positive can receive O positive red blood cells. That means, 3 out of 4 people, or about 76% of the human population can take advantage of this goldar donation.

People with blood type O positive can receive donations from O positive & O negative only. Although this blood type can be used for other blood types, people with blood type O can only receive Goldar O again. Hence, blood type O positive is very much needed in any part of the world.
