In America, some people look up a potential partner's star sign to see their compatibility. If you are not shy to admit, you may have at one time, or another sought advice from the stars. Well, for Japanese people, they do not rely on the astrological signs of personality information; rather it is their blood type.

10 O Negative Blood Type Facts

After all, we all have blood running through the veins of our bodies. But have you ever thought about how your blood type and personality are connected? This concept might seem foreign to us; many truly believe that personality traits are inherently connected to the type of blood you are born with. Although is a fun idea, there's no proof to back it up, meaning blood type personality school to be viewed as more of a myth than a scientific fact. But those who do believe are adamant that blood type plays a significant role in determining a person's personality.

You can use your blood type to understand your unique nature. In countries such as Japan, people are very fond of asking one's blood type.

Blood typing can be a useful tool for employers to assess their potential employees, in marketing companies, and in companies dealing with dating services. Do you know your blood type? Read on and find out more about your personality traits depending on your blood type.

Also, possibly check out who would be your best match depending on their blood type! O, B, A, and AB are the four blood types in the human race. A lot of research on blood types and personality has been carried out in Japan where the majority of the people are blood type A. The second most common blood type is the B blood type. People with blood type AB positive are universal plasma donors. Below are the four blood types and their associated personality traits.

You will be surprised at how accurate some of these are! People with blood type A are clever, passionate, sensitive, and cooperative. They are loyal, patient, and they love peace.

The Power of Heritage

Sometimes, they may be overly sensitive about different things. For instance, they care a lot about etiquette as well as social standards. They do not like to break the set rules on etiquette or the laid down societal standards or rules.

Blood types A personalities are careful decision makers, and they take their time before they can settle on any decision. Besides, they are not good at multi-tasking, as they prefer to handle one task at a time.

Blood type A personality types are very organized, and they do not like haphazard actions. They prefer to keep everything neat and in the right place. They plan everything, and every task that they engage in is carried out with a lot of consistency and seriousness. Many people with OCD fall into this category and end up seeking help from a professional counselor who can help with their compulsive issues. People in this blood type sailing doodles s4 e31 are very stubborn and are easily stressed.

They have high levels of the stress hormone cortisol, and this makes them intense. They do not like fights, and they prefer to be in harmony with everyone, and they like to work in collaboration with others in the community. They tend to keep to themselves more so when they do not want to share their ideas or opinions.

Some of the most common personality traits of blood type A are as follows. They are kind, shy, stubborn, attentive, composed, polite, tense, withdrawn, reliable, perfectionist, sensitive, responsible, tactful, timid, mild-mannered, anxious, earnest, reserved, and polite.Blood types are determined by the presence or absence of certain antigens — substances that can trigger an immune response if they are foreign to the body.

Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching. Do you know what blood type is safe for you if you need a transfusion? There are four major blood groups determined by the presence or absence of two antigens — A and B — on the surface of red blood cells.

There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death. Also, Rh-negative blood is given to Rh-negative patients, and Rh-positive or Rh-negative blood may be given to Rh-positive patients. The rules for plasma are the reverse. There are more than other known antigens, the presence or absence of which creates "rare blood types.

Learn about blood and diversity. Universal donors are those with an O negative blood type. 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. Approximately 45 percent of Caucasians are type O positive or negativebut 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood.

Types O negative and O positive are in high demand. The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood. There are more than other known antigens, the presence or absence of which creates " rare blood types. If you somehow lack an antigen that Like eye color, blood type is passed genetically from your parents.

Whether your blood group is type A, B, AB or O is based on the blood types of your mother and father. Testing difficulties can cause exceptions to the above patterns. ABO blood typing is not sufficient to prove or disprove paternity or maternity. Now that you know how your blood type can help recipients, please schedule an appointment to donate today. Blood Types.

Blood Types and Transfusion Each year 4. Every 2 seconds someone in the US needs a blood transfusion. Use the interactive graphic below to learn more about matching blood types for transfusions. Donate and find out.How did human blood types evolve to what they are today? Some scientists believe it was our first defense against disease.

I still remember when my mother told me I had O- blood. She said it meant I was a universal donor—anyone could receive my blood, but I could only take O- blood in return. I'll admit feeling prideful of this distinction—as if I've been selected for a duty to help others. It's a fact I've never questioned until recently.

After all, w hat's the evolutionary advantage for having such different blood types? It certainly doesn't do us any favors when receiving a transfusion of a blood not of your type could very well kill you.

It was a huge find and he won a Nobel Prize in Physiology or Medicine for it in A few years later researchers would discover the AB group. What differentiates one blood group from another are its antigens. It's a coating around the red blood cell, which helps the body identify which cells are yours. This attack would cause the transfused blood to clot, threatening the life of the patient.

There are two main antigens that form around our red blood cells, they are known as A and B. So, if your blood type AB, then you have both the A and B antigens. Type O lacks the A and B antigens, so the antibodies of a type O patient would attack A or B blood from a transfusion. Think of antigens as a hall passif your blood cells have them, then they won't get any trouble from the hall monitors antibodies. This is another collection of 45 different antigens.

But they're all produced as a single group, so you either have all of them Rh positive or none of them Rh negative. Back when humans first roamed the Earth, we weren't concerned with blood transfusions. But science has yet to explain why some groups of people are more likely to have one blood type over another.

Type A is thought of to be the most ancient. Pre-humans began with type A blood before early humanoids began to exhibit certain mutations in the form of other blood types, which might or might not have turned into survival advantages. One clue to how these mutations survived can be found in their unique resistance to certain diseases.What are rare blood types?

The science of blood transfusion is complex and multifaceted. Determining the correct blood product to transfuse into a patient is of utmost importance to his or her care and recovery. This decision comes down to more than just matching the ABO group of the donor and recipient. Doctors and scientists have discovered more than of these antigens.

Their presence or absence creates our individual blood types. Currently, there are 33 recognized blood group systems. Each group has its own unique combination of antigens.

What is rare? Your blood type is considered rare if it is missing a common antigen or combination of antigens that most people have. Those with an extremely rare blood type lack antigens that To be considered extremely rare, those numbers jump to 1 in 10, Compatibility is key For patients with rare or extremely rare blood types, receiving transfusions from compatible donors is key to successful treatment and recovery.

Rarity runs in the family Blood type is an inherited trait, and many of the factors that determine the unique makeup of your blood type are related to your ethnicity. Certain blood types are more common in certain ethnicities. That means it can be nearly impossible to find a specific rare blood type for a person of one ethnicity in a donor of another ethnicity.

It is vitally important to have a steady supply of blood donations from people of all ethnicities to help meet the needs of our diverse patient population. If you have a rare blood type, it may run in your family. If you have biological siblings, they could have rare blood too.

Talk to your family members about the importance of blood donation and encourage them to give with you. The donation process is more fun when you save lives together! The power of rare blood types You may have heard about the search for blood donors that took place after 3-year-old Zainab was diagnosed with a rare pediatric cancer.

The South Florida girl has extraordinarily rare blood and needed very specific blood donors to help save her life as she battled neuroblastoma. Because she is missing the common antigen known as Indian B, she can only receive blood from people who are also missing that antigen. The only people likely to have the blood she needs are of Indian, Iranian or Pakistani descent. OneBlood tested more than 4, units in the search for blood donors who would be compatible with Zainab, ultimately finding five donors who could contribute to her fight.

Because the special blood she needed was available, Zainab was able to undergo the necessary treatment, surgery and transplant to continue her battle. She has a passion for motivating and educating blood donors through storytelling. Donate Now. I am Oneblood Testimonials Video Gallery. Blood donor basics Target your Type. Donation Methods Can I Donate?Human blood types most likely came to exist to fend off infectious diseases.

The incompatibility of some blood types, however, is just an accident of evolution. 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.

one blood type

Type B is thought to have originated some 3. Starting about 2. And then there is AB, which is covered with both A and B sugars. These sugars are what makes some blood types incompatible: if blood from a type-A donor were given to a person with type-B, the recipient's immune system would recognize the foreign sugars as an invader and cue an attack. The resulting immune reaction can kill. Type O-negative blood is known as the "universal donor" because it lacks the molecules that would provoke that reaction the "negative" means it lacks another type of surface molecule, known as the Rh antigen.

But incompatibility is not part of the reason humans have blood types, says Harvey Klein, chief of transfusion medicine at the National Institutes of Health Clinical Center.

The evolutionary cause, or at least one of them, appears to be disease. For example, malaria appears to be the main selective force behind type O, according to Christine Cserti-Gazdewich, a hematologist at Toronto General Hospital.

Type O is more prevalent in Africa and other parts of the world that have high burdens of malaria, suggesting that blood type carries some sort of evolutionary advantage. In this particular case, the advantage appears to be that cells infected with malaria don't stick well to type-O or type-B blood cells, Cserti-Gazdewich said. Malaria-infected blood cells are more likely to stick to cells with the A sugar and to form clumps known as "rosettes," which can be deadly when they form in vital organs, such as the brain.

As a result, people with type O get less sick when they're infected with malaria, according to a study in the Proceedings of the National Academy of Sciences. On the other hand, people with type-O may be more prone to other diseases. For example, they are known to be more susceptible to Helicobacter pylori, a bacterium that causes ulcers, Klein said.

But research hasn't yet shown whether that or some other disease explains why humans still have blood types. Live Science.

The gist, according to the book that popularized the ideawas that doing so could maximize your performance, boost health, protect from disease, build stronger emotions, and even help you live longer.

In fact, one blood type continues to emerge above the rest: blood type O. Research suggests that people with type O blood are at a lower risk for cardiovascular health issues like stroke and heart attack.

Science suggests that people with AB blood are at an increased risk of memory issues down the line compared to people with O blood. And other research pins people with O blood as less likely to experience certain kinds of cancerlike pancreatic and gastric cancers. Your type is determined by either the presence or absence of antigens on red blood cells, which can trigger an immune response in your body, Kristine Alexander, PhD, a postdoctoral fellow in medicine at the University of Vermont, tells Yahoo Health.

Along these same lines, type AB is a universal acceptor — since it has both A and B antigens, people with AB can take in all kinds of blood from the ABO group, but only type O can give to anyone. Alexander says that it does look as though blood type O is protective in the setting of cardiovascular disease. People with type O blood have lower Von Willebrand factor levels.

And more heart attacks and strokes are caused by blood clots, so anything that can have a part in reducing that risk is beneficial. A different study Etemadi conducted looked at mortality ratesand found that people with type O blood lived longer than those with non-O types.

Research published in the journal Neurology out of the University of Vermont found that people with type AB blood have an increased risk for cognitive problems as they grow older. Even after taking into account race, sex, and where someone lived, the work found that impaired thinking was 82 percent more likely in people with AB blood than people with A, B, or O blood.

Research has also made connections between people with A blood type and obsessive-compulsive disorder. Molecules called soluble E-selectin play an important role in inflammation, due to their involvement in recruiting white blood cells to areas of injury, she says. Related: Type AB Blood? People with blood type O were more likely to survive in places where malaria was a major cause of death.

When it comes to cancer, certain blood types are linked to specific kinds. How come? People with blood type O may also be at a lower risk for pancreatic cancer than people with other blood types.

If you lived in a time or age when bleeding was the main cause of death, things may have been different: Blood O does not have any advantages there — it leads to more bleeding, Etemadi says. But today, cardiovascular issues play a bigger role in death than bleeding. Read full article. Story continues.In general, the rarest blood type is AB-negative and the most common is O-positive. Here's a breakdown of the most rare and common blood types by ethnicity, according to the American Red Cross.

Blood Types - An Introduction to the ABO and Rh Systems

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. 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. Blood typing is particularly important for blood transfusionsbecause certain antigens on blood cells can trigger a person's immune system to attack the donated blood. People who are Rh-negative can only receive Rh-negative blood, but people who are Rh- positive can receive either Rh-positive or Rh-negative blood, the Red Cross says.

What's more, type A blood can be used for transfusions for patients with type A or type AB blood; type B blood can be used for patients with type B or type AB blood; and type AB blood can be used for patients with type AB blood. 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. Live Science. Please deactivate your ad blocker in order to see our subscription offer.
