B Negative (B-) Blood Type: The Rare Ones

The Rarity of B-

If you’re carrying a B negative (B-) blood in your veins, then it means you’re one of the very few ones who have that type of blood!

B negative is a rare type of blood— in fact, only 1.5% of the whole population has this kind of blood. This happens because of the absence of rhesus (Rh) antigens in the blood.

To sum it up, here’s the mix of different blood types in the United States:

  • Caucasian – 2%
  • African-American – 1%
  • Hispanic – 1%
  • Asian – 0.4%

Giving and Receiving

Type B- people can donate their whole blood to those who share the same kind as theirs. The following can also receive from the Type B- group:

  • B+, AB-, AB+ – red blood cells
  • B+, O-, O+ – platelets and plasma

People with Type B- blood are compatible to receive blood from those who have B- and O- types. As for plasma, they can get it from fellow B and AB people.

The B- Traits

The traits of B- people are similar to those who have B+ blood type. The following characteristics apply to people with B blood type in general:

  • Type B people always want harmony in their relationships, which makes them the most balanced group out of all the other blood types.
  • Some of the positive traits of people with B blood type are: adventurous, passionate, optimistic, cheerful, creative, flexible, goal-focused, independent, and animal-loving.
  • However, type Bs also have not-so-positive attributes: they can’t multitask very well, are exceedingly curious about everything, and gets easily irritated when things don’t turn out the way they want to. They also tend to be aloof, self-centered, and forgetful.

Celebrities with Type B Negative (B-) Blood


  • Jack Nicholson
  • Mia Farrow
  • Leonardo Di Caprio
  • Paul McCartney
  • Akira Kurosawa
  • Johnny Depp

As you can see, these are the only famous people who have type B- blood. This is because of the fact that B- is the second rarest blood type, the first being AB negative (AB-).

What Should B- People Eat?

People with Type B- blood should also follow the same diet recommended to those who carry Type B+ blood.

Like B+ people, those who have Type B- blood should eat healthy choices of food for weight loss and overall good health. These options include low fat dairy, green vegetables, eggs, and other types of meat such as lamb, rabbit, mutton or goat.

Understanding Leukoreduction

Car accident victims escaping with injury at all is rare, most are likely need to be transfused with blood products. When someone is severely anemic, doctors eventually give red blood cell transfusions. When patients with blood disorders, are always given platelet transfusion. Patients with severe liver disease may need to be transfused with plasma as part of their recovery.

Ever wondered why transfusions are only for whole blood, red blood cells, platelets, plasma transfusions and none are prescribed for white blood cell transfusion?

Because my dear readers, there is no need for it. In fact, white blood cells are removed from whole blood products before transfusion.

Isn’t that part of the blood that kills viruses and bacteria? This may surprise some of you but this is actually a common process called leukoreduction. Leuko what? The name may sound complicated and too technical but it’s actually easy to remember. Leuko which is from leukocytes is another way of calling white blood cells. The word reduction means the state of being reducing- to the point of elimination in this case.

Leukoreduction is when the white blood cells are removed from whole blood. Easy, isn’t it? But why do we need to take away white blood cells from whole blood before transfusion? Isn’t it an equally important component of blood just like red blood cell, platelet and plasma?

The answers to these questions when you read below.

What is Leukoreduction?
Leukoreduction is the process used to filter and remove white blood cells from whole blood before transfusion. White blood cells are removed because they offer no benefit to the recipient but instead carry bacteria and viruses to the patient.

Patients may experience adverse effects when they receive blood that has not been leukoreduced. Among these are fever with chills, alloimmunization, and the transmission of viruses including cytomegalovirus (CMV), a member of the herpesvirus family which can be harmful for low-birth weight infants and to transplant patients.

Benefits of the Procedure
Before we dig a little deeper, let’s first review the respective functions of the different components of blood in the body.

The red blood cells transport oxygen from the lungs to all of the tissues of the body; the plasma serves as the transport system that delivers various materials between the cells; the platelets help clot the blood in the case of an injury; while the white blood cells protect the body from infectious agents.

They all have wonderful functions, right? But let’s say sorry to white blood cells because it has to be removed from its brothers before a transfusion.

White blood cells may hide infectious disease and some pathogens will be more concentrated in WBCs that the rest of the blood components. There’s also a theory that the donor white blood cells may suppress the recipient’s immune system by interacting with it.

What is Leukoreduction

Benefits of Leukoreduction

In a study made by Dr. Neil Blumberg of the University of Rochester, New York, he said that leukoreduction was significantly useful in reducing infections and other morbidities after surgery, with savings of about $1700 – $2000 per unit of blood transfused. In contrast, transfusion of a patient with non-leukoreduced blood resulted in an increase in overall spending of about $4000 – $4500 per patient.

Scientific journal “Transfusion” published an April 2007 meta-analysis by Dr. Blumberg and others that covered 3093 patients who received leukoreduced blood. The meta-analysis revealed that use of leukoreduced blood decreased the frequency of post-transfusion infection by 50%. Moreover, Blumberg and others reported in a previous study that a shift to universal leukoreduction at Strong Memorial Hospital lessened post-transfusion infection by 33-45%.

About 60-70% of blood derivatives used for transfusions are now leukoreduced. Canada and Europe are moving towards using leukoreduced blood as routine practice.

No one ever would want to be in the situation where blood transfusion are needed, just in case there is, I hope that this helped demystified what leukoreduction is.


We Love Blood Memes!

Memes are all over the internet these days. Technically, a meme is an idea or a style of behavior that spreads from one person to another within a culture. One idea that catches the imagination of people eventually turn it into an internet craze- this is how an  “internet memes” is born. Internet memes are like a virus, spreading from person to person through blogs, social networks, emails or other web-based services.

Most Internet memes evolve as commentary, parody, imitations of real life situations which   spreads rapidly in the blogging community and social networks because its funny, witty and bordering on sarcastic.

Working for a blood donor network has not made us immune to witty and catchy BloodBanker memes.

"Give blood. It's free."

Give blood. It’s free.

There is no substitute to seeing how a person reacts when they see the word FREE anywhere. Giving blood is a donation you are free to become a hero 3 times over.

Y-U-No Meme

Y U No Donate Blood!

“Y U No” meme is one of the most used and popular memes on the internet. The face of “Y U No” guy was taken from a chapter in the Japanese sci-fi manga/anime series Gantz. There, “Y U No” has a new advocacy: to promote blood donation. The “Y U No” guy asks why you’re not donating blood today? And he has a point. Let me ask you that again, “Y U NO DONATE BLOOD TODAY?”. At least “Y U No” is concerned about blood donation and blood shortage. Are you?


“X all the Y” or “X all the things meme”

X all the Y or X all the things meme

The image, which was first published in the comic “This is Why I’ll Never be an Adult”, was made by illustrator Allie Brosh to convey frustration with her inability to keep constant enthusiasm for her daily tasks.

In this image, “X all the Y” enthusiastically announces that you “Give all the Blood!” to help save lives. With an energy as high as that, are you now convinced to Give all the blood away?

"Joseph Ducreux meme"

Joseph Ducreux meme

Another meme that is making the rounds in the Internet is a self-portrait of a man from the 18th century who has that spunk and swag everyone in the 21st century loves! The cheesy grinning man is Joseph Ducreux, a French painter, miniaturist and engraver who is known for his unorthodox style of portrait paintings.

In this meme he asks : “Give thy blood. Thou Knowest it makes sense”. Indeed, donating blood donation makes sense since you are helping save lives.

So you’re a noble man, eh? Prove that to the world by giving blood.

Who hasn’t seen a picture of this cute toddler with a clenched fist with texts saying how successful he has done something? This meme, also known as “Success Kid”, showed up in 2008 and had spread like wildfire across various social media platforms.

"Success Kid"

Success Kid meme

Success Kid has many versions of funny texts around the internet such as: “Went on a date: Saw my Ex”, “Goes to Youtube: First to Comment”, “Overslept: Still First in Office”, “Threw paper wad at trash can: Made it on the first try”, “Ex-Girlfriend sees me: with new Hotter Girlfriend”and a whole lot of proud moments which anyone can easily relate to.

Yes! Success Kid knows he did right by donating blood and saving multiple lives at once. Though blood donation is not for people below 17, the meme characterizes the joy of making it right.

How about you? Have you tried donating blood and experienced the gratifying feeling of saving lives? Maybe Success Kid could inspire you to get your sleeves rolled up. And if you did, you can tell the whole world about it, too!

BloodBanker wants to urge more people to donate blood by using memes to convey a heartily and funny message about the importance of blood donation. It doesn’t matter if you use articles, photos or memes to recruit blood donors. What matters most is we get to send our message across: that blood donation is free, gratifying and a noble thing to do. Donate blood now, and if you can’t, at least help us spread the word. You make yourself a hero either way.

Have Fun While Saving Lives

Do you get bored easily?

Blood donation is a worthy cause yet boredom is probably one of the reasons why 15% of non-donors do not want to give blood. The most common misconception is that blood donation takes more than half of their day. People consider sitting back and doing nothing while your blood fills up a bag is torture and not much fun at all.

We say otherwise! Entertaining yourself while giving blood is the solution to boredom “phobia”. First timers should go with a couple of friends or family to pass the time away with. Here are some other suggestions to spice up your donor session …

Try: Going in as one of the vampires in Twilight

Scruffy hair-waxed hair and a bit of glitter will do, you can also throw in a pair of fake canines too. Who says role playing can’t be done in a donor center?!

Try: Mumbling to yourself as your bag is filled

You may have to do this a couple of minutes until a nurse or phlebotomist asks if you are okay. When they do, give them a big grin and tell them you were testing how attentive people are at blood donation centers.

Try: Taking deep breaths (close to hyperventilating)

Volunteers or phlebotomy trainees are bound to get concerned and would go up to you to see if you’re alright. Assure them you are and tell them you plan to audition for the next SAW movie.

Try: Make small talk

There are centers that have volunteers or interns who get credits for on the job training. You can take it a little further if they’re cute and your type, might as well strike up a conversation while lying there with your blood dripping in a bag.

Try: Betting your buddy that you can fill your bag faster than him

You just got to be hooked up at the same time though. I think there are no restrictions on how many of your cookies you can bet – there’s always a lot of them after you donate blood.

Try: Say you’re giving 2 pints

Let them in on the joke if they start explaining it too seriously. Phlebotomists need to lighten up sometimes, eh?

Try: Pretend to faint 

WARNING: This gag is for the bold hearted. It would be a  sight to have a grown man swoon and faint. Anyway be prepared to have a hearty laugh and own up to pretending.

Try: Asking why the bag looks like it’s twitching

Nurses, phlebotomists and volunteers are always there to answer questions. This will be out of the norm but it’ll get their attention alright.

Doing a good deed like sparing a pint of blood shouldn’t take the fun out of everything. Every one  deserves a good laugh once in a while besides it is a way to make the good deed more interesting. .


Some of the fun stuff we’ve written have come from our friends at LaughtNet.

Blood Types in Japanese culture: True or Sham Science?

For most of us, knowing our blood types is not an utmost priority. Unless there is an emergency, like a transfusion or hospitalization, that thoughts about blood exist. But in Japan, there is more to blood type than meets the eye.

Japanese take blood types very seriously to the point that they use it to determine a person’s personality. As a matter of fact, high school students mention their blood types as a way of introducing themselves in class and matchmaking agencies use blood-type compatibility tests to find your perfect partner. Blood types can even get you hired or fired from a job! Comic books and video game characters even have blood types. To prove their mania for this blood type hype, manufacturers even produce and market a wide variety of blood-type specific products such as blood-type towels and bath soaps, chewing gums, colas, and yes, even condoms.

"Blood Types in Japanese Culture"

Blood Types in Japanese Culture

This may sound absurd, but for Japanese, this thing is completely normal. As to how and why this has become important to them, let’s read more below:

Short History of Blood Type Hype
The study that blood types have something to do with one’s personality is non-statistical and unscientific. Yet interestingly, the Japanese make a big deal out of this.

In 1927, a Tokyo professor named Takeji Furukawa published a paper “The Study of Temperament Through Blood Type” in a journal Psychological Research. He observed the differences in temperament of the students who applied to his school and made conclusions that all humans could be divided into two personality types. According to him, people with blood type A were intellectual and mildly tempered while those with Type B were unintellectual and easily angered. Despite his study was unscientific and lacked the proper case studies with documented evidence, the public were quick to  believe Furukawa’s conclusions.

After Furukawa’s death in 1940, the interest in the theory faded as well. But in 1971, Masahiko Nomi, a journalist and lawyer without medical background, revived and expanded Furukawa’s theories in a best selling series of books “Understanding Compatibility from Blood Types”. His new theories associated some blood types to academic success and different types of crime. Nomi’s work was largely unreliable and uncontrolled, which consequently received negative criticisms from the Japanese psychological community. But even if the methodology of his conclusions was unclear, Nomi’s books remain popular among the Japanese public.

After Masahiko Nomi died, his son Toshitaka Nomi founded the Institute of Blood Type Humanics or “Ketsueki-gata Ningen-gaku Kenkyusho”. Since the Institute’s founding, people’s fascination and interest in “keksu eki gata” or blood type continued to grow. In fact, Masahiko and Toshitaka Nomi wrote more than 65 books and sold more than 6 million copies in Japan. Truly, the idea that blood type and personalities are related to each other was received well by the Japanese despite its illogical and unscientific bases. This is why blood types have been used to hire employees, dictate child-rearing strategies and even find partners!

What Your Blood Type Says About You!
Now that you know the history of blood types in Japanese culture, let’s have a peek at the characteristics that are attributed to each blood type. Check if your blood type matches your personality, too!

People with Type A blood group are believed to be kind, hospitable, hard working, earnest, creative, patient, responsible, sensible and reserved. They consider things carefully and can understand other people’s feelings easily. They do not express themselves just to avoid possible conflict and they are calm even when accidents happen. Moreover, Type A’s are artistic, shy, very serious, reliable and levelheaded. But sometimes they can be overearnest, tense, fastidious and stubborn.



Hunters are optimistic, passionate, strong, wild, active, friendly and flexible thinkers. They are not pretentious, they like to play, love festivals and parties, but they are afraid of being alone. Type B’s like to go their own way and are masters of breaking rules. Nonetheless, this blood group are the most practical of all and they are specialists in what they do. They stick to a goal and follow it through the end, even if it looks impossible. The bad traits of type B’s are selfish, unforgiving, irresponsible, and unpredictable.




Those who belong in the Type AB blood group are calm, rational, sensitive, sociable, adaptable, careful and efficient. They have strong spirituality, they chase ideals and dreams and they do not like interference from other people. Type AB’s are known to have “split personality” because they are considerate of other people’s feelings but are strict with themselves and those close to them. In addition, they are helpful, outgoing, confident and frank. But sometimes, these people can be indecisive, forgetful, critical and moody.



The warriors are realistic, ambitious, optimistic, outgoing, expressive, passionate and athletic. They are highly motivated, very cautious and romanticists. Type O’s are good at developing economic concepts and are devoted people, usually with a strong desire to monopolize. They are peaceful, carefree, big-hearted, benevolent and generous. On the other hand, they can be vain, jealous, arrogant, rude, greedy, clumsy and unreliable.


The Japanese belief in blood type personalities may be interesting, especially to those who haven’t heard of this yet. However, Satoru Kikuchi, a psychologist at Shinshu University argues that this belief is “sham science” and the idea encourages people to judge one another by their blood types. If you think that the characteristics under your blood group perfectly matches you, it could just be purely coincidental. The scientific community dismisses these beliefs and considers this as pseudoscience.

Unfortunately, this belief has already caused emotional damage to most Japanese. Since this creates stereotypes among people, “Bura-hara”or Blood type harassment has been blamed for several unwanted yet completely avoidable social and personal issues such as bullying, loss of job opportunities and ending of happy relationships.

Knowing your blood type is good, but once it comes to a point when a person’s destiny is determined by the type of his blood, this is where we have to examine ourselves. Our character and future are determined by our choices and circumstances, not by the blood type that we are born with.
