Some Bloody Good Questions About Blood Types
There remain many mysteries regarding blood types. For example, we still dont know why humans evolved the A and B antigens. Some theories point to these antigens as a byproduct of the diseases various populations contacted throughout history. But we cant say for sure.
In this absence of knowledge, various myths and questions have grown around the concept of blood types in the popular consciousness. Here are some of the most common and their answers.
Do blood types affect personality?
Japans blood type personality theory is a contemporary resurrection of humorism. The idea states that your blood type directly affects your personality, so type A blood carriers are kind and fastidious, while type B carriers are optimistic and do their own thing. However, a 2003 study sampling 180 men and 180 women found no relationship between blood type and personality.
The theory makes for a fun question on a Cosmopolitan quiz, but thats as accurate as it gets.
Should you alter your diet based on your blood type?
Remember Galen of Pergamon? In addition to bloodletting, he also prescribed his patients to eat certain foods depending on which humors needed to be balanced. Wine, for example, was considered a hot and dry drink, so it would be prescribed to treat a cold. In other words, belief that your diet should complement your blood type is yet another holdover of humorism theory.
Are there links between blood types and certain diseases?

Is A+ A Good Blood Type
As an A Positive donor you are important to maintaining the blood supply in our community. Annually more than 120,000 units of blood, platelets, and plasma are required to meet the needs of the hospitals we serve, and your blood type is critical in saving the lives of patients in your community…. view details
What Is The Best Blood Type
That depends on who you ask.
In some respects, the best blood type might actually be the rarest blood type, AB+. This is because AB+ blood type is known as a universal receiver. In other words, if you have AB- blood type and need a blood transfusion, you can get it from any other blood type.
But then there is another blood type to consider, the universal donor.

How Is Blood Type Determined
A person’s blood type is based on whether or not they have certain molecules or proteins called antigens on the surface of their red blood cells, according to the National Institutes of Health. Two of the main antigens used for blood typing are known as “A antigen” and “B antigen.” People with type A blood only have A antigens on their red blood cells and those with type B blood have only B antigens. Individuals with type AB blood have both people with type O blood have neither.
Another protein, the “Rh factor” also known as the “Rhesus” system is also present or absent on red blood cells. A person’s blood type is designated as “positive” if they have the Rh protein on their red blood cells, and “negative” if they don’t have this protein.
In 1961 A Female Aboriginal Australian Was Found To Have Rh
Only 43 people worldwide are known to have the rarest blood type, Rh-null. In 1961, a female Aboriginal Australian was found to have rh-null. It served as the foundation for Galen of Pergamums bloodletting prescription, which gave rise to medical quackery.
It took until 1665 for the first successful human-to-human transfusion, and many transfusion patients continued to mysteriously pass away after that. Karl Landsteiner, an Austrian doctor, started working on a system to categorize blood types in 1901. The eight common blood types are a simplification of the actual functioning of blood types.
If all 61 potential Rh antigens are absent, blood is said to be Rh-null. People with O negative blood are referred to as universal donors for this reason. A 2003 study found no connection between personality and blood type.
Data from 1,455 participants were analyzed in a study from the University of Toronto, and no evidence was found to back up the idea that your diet should match your blood type. According to one analysis, people with type O blood have a lower risk of having a stroke or heart attack than those with type AB blood. A $4 solar desalination device created by MIT could supply an entire family of four with drinking water.

It Has Only Been Found In Two Families Worldwide One In Australia And One In Canada
The 36 blood groups that make up the blood antigen classification can be identified by 34 of them. A team in Australia found that a regular donor had a previously unidentified antigen in the 1990s. Since that time, the International Society for Blood Transfusion has acknowledged the rare SARA antigen.
It has only been found in two families worldwide, one in Australia and one in Canada. The South Texas Blood & Tissue Center was established 45 years ago to supply the South Texas area with blood. Today, we realize that giving the gift of donation is a powerful, individual decision that has the potential to change someones life.
In order to develop a broad range of therapies, our team has also expanded its programs and partnered with influential figures in the healthcare sector.
Controlling The Populace Is The Churchs Only Issue
In the United States, 33 percent of people have blood type A positivity while 45 percent have blood type O positivity. Ninety percent of all human blood cells are these two types. Less than 3% of people have one of the other blood types .
These kinds frequently bear names of the owners or the locale where they originated. The majority of the resistance in India is eliminated, and the Church of Jesus Christ completely conquers the nation in the year 4032. With the exception of the Artic and Antarctica, the Vatican strategically positions its troops to maintain control over the entire world.
They even establish a covert branch of their military in space, which is how they manage to eventually conquer the Moon and a large number of asteroids throughout the Solar System. Controlling the populace is the Churchs only issue. All women between the ages of 15 and 50 are eventually forcibly removed from their homes and forced into government service because things become so bad.
All females younger than 25 are rounded up and loaded onto a big ship that travels through space. The Church now has complete control over the entire world. After Blood-Bourbon was discovered, numerous organizations tried to make other blood types from it.

What Blood Type Is The Universal Donor
People with type O blood are called “universal donors” because this type can be used for patients with any blood type.
Type O blood is often in short supply in hospitals, due to demand for this universal donor type, according to the Red Cross. In particular, type O-negative blood is in high demand because it’s the one most often used for emergencies, when there may not be time to determine a patient’s blood type.
What Is The Oldest Blood Type
There are four main blood types. Blood type A is the most ancient, and it existed before the human species evolved from its hominid ancestors. Type B is thought to have originated some 3.5 million years ago, from a genetic mutation that modified one of the sugars that sit on the surface of red blood cells.

Red blood cells are made of antigens, which can be seen on them like sprinkles on a donut. There are only nine active donors and only 43 Rhnull blood types have ever been identified. Rhnull is regarded as universal blood for anyone with a rare Rh blood type because of its extraordinary capacity for lifesaving.
What Is Most Wanted Blood Type
Why? O negative blood can be used in transfusions for any blood type. Type O is routinely in short supply and in high demand by hospitals both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.

This Blood Type Is Present In Fewer Than 1 In 1000 People
The absence of antigens in the Rh system results in the blood type Rh-null. This blood type is present in fewer than 1 in 1,000 people. Stomatocytes, which are Red Blood Cells that are osmotically fragile, are known to be present in people with this syndrome.
In particular, a molecular change in the RHCE gene with a deleted RHD gene causes an amorph type of the condition, which is caused by two distinct genetic mechanisms. Lack of Rh blood group antigens is the main cause of the Rh-null blood type. Rh polypeptides, as well as Rh-associated glycoprotein and glycophorin, are absent in R-null cells.
The red blood cells of the individual may have an uncommon or unusual shape or structure. They might behave differently as a result, which could result in a number of conditions.
There’s Rare Then There’s Rhare
After the eight common blood types, we’ve got a few unicorns. Something like 160 of the 342 blood group antigens are high-prevalence, which means most people have them on their red blood cells. If you lack an antigen that 99 percent of people have, then your blood is considered rare. If you lack one that 99.99 percent of people have, then congratulations: You’re Spiderman. Just kidding, probably.
The rarest blood type in existence is Rhnull blood. This stuff is characterized by a complete lack of antigens in the Rh system, which is the largest blood group system. This includes the D antigen , plus the other 50-something antigens in the group. This blood type is so rare that only 43 people on Earth have ever been reported to have it, and there are only nine active donors. Until 1961, doctors assumed a person lacking all Rh antigens would never even make it out of the womb alive. “It’s the golden blood,” Dr. Thierry Peyrard, the Director of the National Immunohematology Reference Laboratory in Paris, told Mosaic.
Besides making someone feel really special, Rhnull and other rare bloods are extremely valuable. “Because Rhnull blood can be considered ‘universal’ blood for anyone with rare blood types within the Rh system, its life-saving capability is enormous. As such, it’s also highly prized by doctors â although it will be given to patients only in extreme circumstances, and after very careful consideration, because it may be nigh on impossible to replace,”Mosaic reports.

Most Common And Rarest Blood Group In India
Blood, as you know, is the life fluid. Its flow in our circulatory system makes our life possible. 45% of the blood is made up of the Red Blood Cells and 55% is plasma. The most widely rare blood group in the world/ india use blood categorization system is called the ABO system. It is based on the antigens found on the surface of RBCs.
- If antigen A is present on the RBC surface, blood type will be A
- If antigen B is present on the RBC surface, blood type will be B
- In case both these antigens are present, blood type will be AB
- If none of these is antigens is present on the RBC surface, blood type will be O
- These four blood groups are find in two versions positive and negative. Yesterday we publish an article about the worlds rarest blood type. rare blood group in the world / India. A reader ask us a relate question on what are the most commonly found blood groups in the Indian population? Today we will discuss the same.
Because blood type is a trait that is genetically determined blood types tend to show prevalence in a geographic area.
Most Rare Blood Type By Ethnicity
The least common blood type in the U.S. is AB-, with less than 1% of the population having this type.
Statistics from the American Red Cross show that the following are the most rare forms of the major eight blood types in the U.S.:
- African American: 0.3% AB-negative, 1% B-negative, and 2% A-negative
- Latin American: 0.2% AB-negative, 1% B-negative, and 2% both A-negative and AB-positive
- Asian: 0.1% AB-negative, 0.4% B-negative, and 0.5% A-negative
- Caucasian: 1% AB-negative, 2% B-negative, and 3% AB-positive
A and B antigens only represent two of approximately 600 other known antigens that can differentiate blood types. It is important to make a distinction between the rarest of the eight most common blood types and the extremely rare subtypes.
Having an antigen that most people do not have, or missing an antigen that most people do have, means that an individual has a rare blood type. According to the International Society of Blood Transfusion, if only 1 in 500 people are missing the same antigen as an individual, their blood type is rare. If only 1 in 1,000 people lack it, the individuals blood type is very rare.
In addition, scientists have identified 36 different blood group systems, some of which can cause problems with blood transfusions.
Some of these rare blood types and blood group systems are distinctly more common in certain ethnic groups. The American Red Cross data below list the rare blood type and the ethnic group in which it is most common:

Blood Is Significantly More Prevalent Than Rh
People with Rhnull blood do not have Rh antigens on their red blood cells, in contrast to other blood types. A blood type is considered rare by the American Red Cross if fewer than one in 1,000 people have it. Only 0.6 percent of Americans have AB- blood, compared to approximately 63 percent of people worldwide who have O blood.
Blood is significantly more prevalent than Rh- blood all over the world. The prevalence of O blood is less common and that of B blood is more prevalent in Eastern Europe and Central Asia. As long as the Rh factor is compatible, a recipient with type AB blood can be used universally.
Asking a doctor about getting safe blood transfusions is advised for people with rare blood types.
Why Donating Blood Is Important
Donated blood can be turned into different medical treatments, depending on which blood type you have. For example, whole blood from type A, type O positive and type O negative is always needed. People with type AB or type B can donate plasma, which is vital for patients with injury, severe burns or blood diseases.

Red Blood Cells What Are The Different Blood Types
The International Society of Blood Transfusion recognizes 43 different blood group systems, the most famous of which are the ABO system and the Rh system, which are often used together.
The ABO system determines blood type based on a combination of two different antibodies and two different antigens, whereas the Rh tests for something called the Rh factor and determines if you have an Rh positive blood type or an Rh negative blood type.
In other words, ABO gives the letter, Rh gives the plus or minus .
Red blood cells that present molecules of a certain type are termed Type A blood cells, while red blood cells that present another type of molecule are termed type B blood cells. Red blood cells that display both types of molecules on their surface are termed type AB blood cells, while cells that do not display either molecule are termed type O blood cells.
The human immune system recognizes these molecules and, upon encountering a molecule different from the type regularly present in the body, treats it as a foreign element that should be attacked. For example, if a person with type O blood receives a type A blood donation, his body will recognize the molecules of type A blood as foreign, consider the donor red blood cells as invaders and attack them. That is why it is imperative to adjust the donor blood type to the recipients blood type.
