What Are The Four Major Blood Types
The four major blood types are:
In addition to this, blood types can be either negative or positive, depending on the absence or presence of the Rh factors D antigen, another protein. If you have the Rh factors D antigen as most people do, you are said to be Rh positive. If you dont have it, youre said to be Rh negative. Being Rh negative is less common than being Rh positive. When you consider the major A and B antigens and Rh factors together, there are eight common blood types.
Where Do Uncommon Blood Donations Arrive From
Rare blood types are supplied in three different ways:
The most preferred choice is to use fresh blood cells from regular donors.
Donors with unusual blood types are being contacted and asked to donate.
Using unusual frozen blood – for the rarest blood types is a final resort. These blood types may be preserved for up to 30 years and then warmed.
In conclusion, there are many blood typing methods, but the ABO and Rh systems, which offer the eight basic blood types, are the most commonly recognized. Surprisingly, not all ‘foreign’ antigens are similarly likely to be targeted to eliminate antibodies. Although therefore, there are 36 identified blood group systems overall. Few blood types are avoided during blood transfusions.
AB-negative blood is the rarest blood type of all the eight basic blood kinds. Bombay blood group and Golden blood or Rh-null are the sporadic blood groups. However, because blood type is connected to heredity, no one style is called the world’s most irregular.
A person with an uncommon blood type will have a more challenging time receiving a blood transfusion. It can also raise the risk of specific health problems, particularly after an organ transplant, after particular health conditions, and during pregnancy.
It is critical to understand one’s blood type and find one who may take a quick blood test. In some cases, when donating blood for the first time, many people discover their blood type.
How Does Blood Type Affect Pregnancy
The Rh factor is inheritedthe fetus can get its Rh factor from either the father or the mother. There can be problems if you are Rh negative and your fetus is Rh positive.
If you are pregnant, your first visit to your obstetrician will involve a blood test to find out your blood type and possibly to screen for antibodies. If the mothers body reacts to a positive Rh factor in the fetus blood, her body will create antibodies that can begin to attack the blood of the fetus.
So, to prevent this damaging reaction, a woman who is Rh-negative will be given a medication called Rh immunoglobulin to block the antibodies from attacking the red blood cells of the fetus.

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.

What Causes Kidney Cancer In Children
Cancer happens when cells in the body have changes in their DNA that cause them to grow and divide out of control. Its still unknown what exactly causes these changes to happen in children with kidney cancer.
Researchers have identified several genetic changes associated with kidney cancers in children. However, not all children with kidney cancer have these changes. Overall, more research is needed into the cause of kidney cancer in children.
In order to diagnose kidney cancer, your childs doctor will first do a physical exam and get your childs medical history.

Rhnull The Rarest Blood Type On Earth Has Been Called The Golden Blood
The extremely rare blood type is shared by only a handful of people on Earth.
There are eight common blood types. Keyword there? Common. If what you know about blood stops right around there, then this is all going to escalate very quickly. There are literally millions of varieties of blood types, and the rarest one is shared by fewer than 45 people on Earth. Talk about exclusive.
Why Golden Blood Is So Valuable
You may know somebody who brags about having the super-rare AB-negative blood type, common to only 1% of human beings . However, some blood is far rarer than this. Golden blood in particular is the rarest blood type on earth, with just 43 recorded cases to date .
There are many more blood types than most people realize, but the blood type system used for determining blood transfusions usually divides blood into just eight groups . Blood types are determined by the antigens present in your blood , with rarer combinations resulting in rarer types.
There are lots of different antigens a person can potentially have, but many people have the A or B antigens, or a combination of the two. Type O blood has neither A nor B antigens and is the most common blood type . Together they make up the four common blood type groups: A, B, AB, and O. These four groups are in turn divided into positive and negative, depending on whether or not they have the Rh-D protein. Some people have no Rh antigens at all and fall into a group of their own the Rh-null or golden blood type.

What Is The Most Common Blood Type In China
In most areas of China, the distribution characteristics of ABO blood groups were O > A > B > AB. Similar results were seen in the studies conducted in South-West Nigeria. However, in other regions, such as Pakistan, B blood groups was the most common, while in Istanbul, the A blood groups was the most common.
What Are The 3 Rarest Blood Types
The blood types vary depending on the genetic makeup of an individual. Since there are differences in the distribution of genes in different parts of the world, the rarest and most common blood groups also vary in different populations across the globe. The rarest blood type in the United States is
- the AB- blood type, which is seen in just 0.6 percent of people followed by

Positive Or Negative Blood
The D antigen in the Rh system determines whether you have positive or negative blood.
If you have the Rh D antigen, your blood type is positive. If you lack the Rh D antigen, your blood type is negative.
77% of our donors are Rh D positive.
There are four other main antigens in the Rh system. Your combination of these makes up your blood subtype.
Ethnicity And Rare Blood Types
Your blood type is inherited from your parents in the same way as eye or hair colour.
This means you are more likely to share the same blood type or subtype as someone from the same ethnic background.
For example, Ro is a rare subtype but its ten times more common in black people than white people.
Growing demand for the Ro subtype is one of the reasons why we need more black donors.

What Is The Treatment For Kidney Cancer In Children
Surgery is a common treatment for kidney cancer in children. When part or all of a kidney is removed, its called a nephrectomy.
Many times, Wilms tumors and other childhood kidney cancers are treated using a radical nephrectomy. This is when the entire kidney, including the tumor, is removed. Nearby lymph nodes may be removed as well.
A partial nephrectomy is the removal of the tumor and some of the surrounding kidney tissue. It may be done if the cancer affects both kidneys. Its aim is to get rid of the cancer and preserve as much kidney function as possible.
Radiation therapy and chemotherapy may also be used for treating kidney cancer in children. These treatments may be recommended:
- before surgery to help shrink a tumor
- after surgery to help get rid of any remaining cancer cells
- when surgery isnt recommended as a treatment option
- if the cancer has come back or spread to other areas of the body
Its also possible that targeted therapy or immunotherapy may be used, depending on the specific type of cancer and its stage.
Since some kidney cancers in children are quite rare, a doctor may also suggest getting treatment through a clinical trial. Clinical trials are used to evaluate the safety and effectiveness of new kidney cancer treatments.
Some of the potential risk factors of kidney cancer in children are:
- having a family history of kidney cancer or childhood kidney cancer
- having certain genetic conditions, including:
- Beckwith-Wiedemann syndrome
How Is My Blood Type Determined
Its inherited. 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.

* Note: If you have questions about paternity testing or about blood group inheritance, your primary care physician should be able to provide you with an appropriate referral. Testing difficulties can cause exceptions to the above patterns. ABO blood typing is not sufficient to prove or disprove paternity or maternity.

Why Are Rare Blood Subtypes Important
Most blood transfusions are based on the ABO and Rh groups.
But if someone needs ongoing transfusions, blood works best when it closely matches their own.
If you have a rare subtype, your blood could be vital for a patient who also shares that subtype.
If you give blood, you’ll find out if you have a rare subtype after your first donation.
How And What Makes Blood So Rare
Although the ABO and Rh blood types are the most crucial for blood transfusions, 36 more blood groups have been identified.
Antigens are carbohydrates and proteins located on the exterior of red blood cells and are unique to each blood group. Because there are over 600 antigens, there is room for diversity between persons.
A rare subtype could be identified by unusual antigens or the absence of common antigens in the blood.

What Is Kidney Cancer
The kidneys are two bean-shaped organs that are found in the upper back part of the abdomen. Their function is to filter waste as well as excess salt and water from your blood. These filtered substances eventually become urine.
Kidney cancer is cancer that starts in the kidneys. It happens when cells in the kidneys begin to grow and divide out of control.
, almost 9 out of 10 kidney cancers in children are Wilms tumors.
Wilms tumors typically develop between the ages of 3 and 5 years . They often only affect one kidney , but in rarer cases can affect both kidneys .
Most Wilms tumors have grown to be very large by the time of diagnosis. Theyre often felt as a mass in the abdomen and may be first noticed when a parent is bathing or dressing a child.
Other types of kidney cancers are less common in children, but can still occur. Some examples include:
- Mesoblastic nephroma: This type is often diagnosed in the first 3 months of life.
- Renal cell carcinoma:Renal cell carcinoma is the most common type of kidney cancer in adults and happens
Whats The Rarest Blood Type
AB negative is the rarest of the eight main blood types – just 1% of our donors have it.
Despite being rare, demand for AB negative blood is low and we dont struggle to find donors with AB negative blood.
However, some blood types are both rare and in demand.
This includes the Ro subtype, which is often used to treat people with sickle cell.
Only 2% of donors have it but demand for it is increasing by 10-15% each year.
The combination of being rare and sought after makes people with these blood types very important donors.

Discovery Of A New Rare Blood Type Could Save The Lives Of Future Newborns
The devastating loss of a pair of newborns has provided critical insights into a rare set of blood types spotted for the first time in humans 40 years ago.
“This work demonstrates that even after all the research conducted to date, the simple red blood cell can still surprise us,” says University of Bristol cell biologist Ash Toye.
Blood typing describes the presence and absence of combinations of proteins and sugars that coat our red blood cells’ surfaces. Though they can serve different purposes, our body generally uses these cell-surface antigens as identification markers with which to separate self from potentially harmful invaders.
We’re most familiar with the ABO and rhesus factor blood group systems, thanks largely to their prime importance in matching blood transfusions. But there are actually many different blood group systems based around a wide variety of cell-surface antigens and their variants.
Most of the major ones were identified in the early 20th century, though a late-comer to the collection, called Er, only popped onto our radar in 1982, forming the foundation for a 44th blood group. Six years later, a version named Erb was identified. The code Er3 was used to describe the absence of Era and Erb.
While it’s been clear for decades now that these blood cell antigens exist, too little has been known about their clinical impact.
Their research was published in Blood.
Is Your Blood Cmv Negative
CMV is a common virus found in the environment. It can be spread through body fluids, including blood transfusions. About 50% of the general population is infected. It is not a serious infection, except for people who are already in compromised health conditions, such as newborn babies or pregnant women. In these cases, the CMV virus could cause birth defects.
- Doctors request CMV Negative blood for transfusions for newborns or other specific patients where the presence of the CMV virus could cause serious health complications.
- Unlike blood type, CMV status can change over time, so be sure to check your donor card for your CMV status.
