A Positive Blood Type: Everything About Being A+

This article presents the complete beginner's guide to A+ Blood Guide.

What Is Blood?

Your blood is made up of fluids and solids. A portion of a fluid called plasma is made up of water, salt, and protein. More than half of your blood is plasma. The solid portion of your blood contains red blood cells, white blood cells, and platelets.

Red blood cells (RBCs) carry oxygen from your lungs to your muscles and organs. White blood cells (WBCs) fight infection and are part of your immune system. Platelets help the blood to drain when cut or sliced. The bone marrow, a sponge inside your bones, makes new blood cells. Blood cells are constantly dying, and your body is making new ones. Red blood cells live about 120 days, and platelets live for about six days. Some white blood cells live for less than a day, but others for much longer.

There are four types of blood: A, B, AB, or O. Also, blood can be Rh-positive or Rh-negative. What kind of type is important if you need a blood transfusion. And your Rh factor can be important if you are pregnant - a conflict between your type and your baby can cause problems.

Blood tests such as blood pressure tests help doctors diagnose certain diseases and conditions. They also help to evaluate the function of your organs and show how the treatment works. Problems with your blood pressure may include blood disorders, obesity, and platelet disorders. If you lose a lot of blood, you may need a blood transfusion.

Blood is essential to life. The blood circulates in our body and carries essential nutrients, such as oxygen and nutrients to our body cells. It also transports metabolic waste products away from those same cells. There is no substitute for blood. It will not be done or done. Donors are the only ones who donate blood to patients who need a blood transfusion. Four basic components make up human blood: plasma, red blood cells, white blood cells, and platelets.

Red Blood Cells

Red blood cells make up 40% -45% of your blood volume. They are produced at a rate of four to five billion per hour in your bone marrow. They have a life cycle of about 120 days.


Platelets are an amazing part of your bloodstream. The platelets are very small in our blood cells and look like tiny plates in their way. Platelets control bleeding. Wherever a wound appears, a blood vessel will send a signal. The platelets receive that signal, travel to the site, and alter their "active" structure, growing tall tents to connect to the vessel and forming clusters to seal the wound until it has cooled.


Plasma is a fluid component of your blood. Plasma is yellow and is made up mostly of water, but it also contains proteins, sugars, hormones, and salts. It carries water and nutrients to your tissues.

White Blood Cells

Although white blood cells (leukocytes) make up only about 1% of your blood, they are very important. White blood cells are responsible for one's good health and protection against illness and diseases. Like red blood cells, they are constantly producing bone marrow. They flow into the bloodstream and attack foreign bodies, such as bacteria and viruses. They may even stop the flow of blood to augment the specific tissues.

What Are The Types Of Blood?

Blood groups: There are four blood groups (blood types) - A, B, AB, and O. Your blood type is determined by the genes you receive from your parents. Each group may have RhD positive or RhD negative, which means they are more than eight blood groups.

Antibodies and antigens: Blood is made up of red blood cells, white blood cells, and platelets in plasma. Antibodies and antigens in the blood characterize your blood type. Protein antibodies are found in plasma. They are part of your body's natural defences. They detect foreign substances, such as germs, and warn of your immune system, which destroys them. Antigen molecular proteins are found on red blood cells.

ABO System

The ABO system defines 4 major blood groups:

  • Blood group A - contains A antigens A red blood cells that have antibodies to B in plasma
  • Blood group B - contains B antigens that have antibodies to A in plasma
  • Blood group O - has no antigens, but both anti-A and anti-B plasma
  • Blood group AB - has both antigens A and B, but no antibodies

Blood group O is the most common blood group. About half of the UK population (48%) has blood group O. Accepting blood from the wrong ABO group can be dangerous to health. For example, if a person with group B blood is given group A blood, his immune system will attack the cells of group A. That is why group A blood should not be given to a person with group B blood and vice versa. Since red blood cells in group O are free of A or B antigens, they can be safely supplied to any other group.

Rh System

Red blood cells sometimes contain another antigen, a protein known as the antigen. If this is the case, your blood type is RhD positive. If not, your blood group has RhD negative. This means you can have 1 in 8 blood groups:

  • RhD positive (A +)
  • RhD negative (A-)
  • B RhD positive (B +)
  • B RhD negative (B-)
  • O RhD positive (O +)
  • O RhD negative (O-)
  • AB RhD positive (AB +)
  • AB RhD negative (AB-)

About 85% of people in the UK have RhD positive (36% of people have O +, the most common type). In most cases, O RhD negative (O-) blood can be safely given to anyone. It is often used in medical emergencies where the blood type is not immediately known. It is safe for most recipients because it has no A, B, or RhD antigens on the surface of the cells and is compatible with all other ABO and Rh blood groups.

Blood Group Tests

To identify your blood group and other parameters, your red blood cells are mixed with different antibody solutions. For example, if the solution contains anti-A antibodies, and you have A antigens in your cells (you are a blood group A), they will accumulate. If the blood does not respond to any antibodies against A or B, it is the blood group "O". A series of tests with different types of antibodies can be used to identify your blood group.

If a blood transfusion is given - when blood is transfused from another person - your blood will be tested with a sample of donor cells containing ABO and RhD antigens. In the absence of a reaction, donor blood with the same type of ABO and RhD may be used.

Pregnancy: Pregnant women are regularly screened for blood clots. This is because if the mother does not have RhD, but the baby receives RhD-positive blood from the father, it can cause problems if left untreated. RhD-free women of childbearing age should always receive RhD-free blood.

Donors around the world are those with blood type O negative. Why? O blood can be used for transfusions of any type of blood. Type O is often in short supply and is in high demand in hospitals - both because it is the most common blood type and because O-free blood is the universal blood type needed for emergency transfusions and deficient infants. About 45 percent of Caucasians are O (good or bad), but 51 per cent of African-Americans and 57 per cent of Hispanics are type O. Thus, young and diverse people play a vital role in meeting the ongoing need for blood. The O-negative and O-types are much needed. Only 7% of people are O negative. However, the need for O-negative blood is very high because it is widely used in emergencies. The need for O + is high because it is a common blood type (37% of people). The universal red blood donor has blood that does not have Type O. The universal plasma donor has blood Type AB. 

Blood type (also known as blood group) is a blood system based on the presence and absence of antibodies and antigenic properties found in the upper layer of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group's system. Some of these antigens are also present in many cell types of various tissues. Many of these red blood cells produce antigens that can mutate from one allele (or another gene) and combine to form a blood group system.

Blood types are inherited and represent the contributions made by individual parents. As of 2021, a total of 43 blood group programs have been recognized by the International Society of Blood Transfusion (ISBT). Two important principles of blood group are ABO and Rh; determined a blood type (A, B, AB, and O, and + or - indicating RhD status) to qualify for a blood transfusion.

A+ Blood Type

Blood type is also known as blood group. It is a blood system that depends on the presence and absence of antibodies. It also depends on the anti-inflammatory properties on the surface of red blood cells (RBCs). Let's learn more about the Blood Group "A" program and the ABO. Antigens can be proteins, carbohydrates, glycoproteins, or glycolipids depending on the blood group system.

As we know, there are four categories of blood or blood types, namely A, B, AB and O. Your blood type is determined by the genes you have inherited from your parents.

Before we find out about blood type, let us first take a look at antibodies and antigens. Blood contains red blood cells, white blood cells, and platelets in plasma. About 45% of blood is made up of blood cells (red and white), and the other 55% is plasma. The immune system is nothing but plasma proteins. They are part of the body's natural defences. They see foreign objects that can harm life as germs and warn the immune system to fight them off and destroy them. On the other hand, antigen molecules are proteins found in red blood cells.

The presence of proteins in red blood cells called antigens defines a person's blood type. This means that if antigen A is present in your blood, then you have type A blood, while if antigen B is present, then a person has type B blood. If both A and B are present, then it is the blood group "AB". If no antigen is present, then a person has blood type O.

Anaemia consists of red blood cells carrying oxygen throughout the body. It also contains white blood cells that help fight infections, as well as platelets that help control blood.

There are eight types of blood that most of us are aware of.

  • A-positive
  • A-negative
  • B-positive
  • B-negative
  • AB-positive
  • AB-negative
  • O-positive
  • O-negative

These are ABO and Rh + and Rh blood group systems.

We will learn about blood group A +.

When a person's blood group is A positive, it means that the blood contains type A antigens containing a protein known as rhesus (Rh) factor. Antigens are markers on the surface of a blood cell. According to the American Red Cross, it is one of the most common blood types.

Why Do People Have Blood Type A +?

Blood type is hereditary. If a person has Type A, it means that his or her parents had one combination of blood types which may be mentioned below:

  • AB and AB
  • AB and B
  • AB and A
  • AB and O
  • A and B
  • A and A
  • O and A

And if the parents had the following combinations of blood types the child would not have type A blood type:

  • B and B
  • O and B
  • O and O

There is no scientific evidence that blood types are associated with certain personality traits. It is an ongoing theory of Japanese culture called "ketsuekigata." For those who believe in this theory, A + blood type personality is associated with time, stubbornness, honesty, responsibility, patience, restraint, rationality, and creativity.

If a person has to type A blood, they can get type A blood or type O blood type. According to the Red Blood Cross organization, there are more than 600 known antigens, and their presence or absence creates "unusual blood types". Your blood is rare if it does not have the antigen of 99% of people who hope for it. If you somehow do not have antigen i.e., 99.99% is positive. Therefore, your blood type is very rare.

Recently, a new Chinese study revealed that people with blood type "A" are at greater risk of getting coronavirus infection than any other blood type. And according to scientists, people with blood group "O" are more resistant to the virus than people with any other blood group. Let's see what it is.

Researchers are studying COVID-19 in its epicentre, in Wuhan and the city of Shenzhen. They found that half of all Type A patients infected and killed by the disease were "significantly higher" than those of the same blood type in the general population. Some studies indicate that patients with an "O" blood type make up a small percentage of those who become infected and die from the virus.

Researchers at Wuhan-Based Medical Research Center wrote that "people of blood group A may need specialized personal protection to reduce the risk of infection". The team, led by Wang Xinghuan, trained the study as "first", and much work needed to be done to improve the findings. Let us tell you that the study was published on It compared the blood types of 2,173 certified cases of coronavirus in Wuhan and Shenzhen with more than 3,694 healthy residents in the Wuhan area.

It was found that 31.16 percent of Wuhan residents had blood type A and 37.75 per cent of the coronavirus-tested patients at the local Wuhan Jinyintan hospital had the same blood type. And a sample of cases of coronavirus patients in the hospital showed that 25.8 per cent had an "O" blood type compared to 33.84 per cent in the general population. In addition, the study also examined 206 patients who died of coronavirus and found that 85 victims, or 41.26 per cent, had Type A. blood. Only 52 of those who died, or about a quarter, had Type O blood. Researchers in the city of Tianjin Gao Yingdai said "there is no need to panic.

It does not mean that blood type A will be 100% infected, and on the other hand, people with blood type O are completely unsafe. However, safety measures need to be taken as hand washing and compliance with guidelines issued by the authorities.


Having blood type A (also defined as A +) means that a person has type A. antigens A mark + is determined by the presence of a rhesus protein known as Rh factor. And if the Rh factor is not present, it means we are no longer talking about A + blood type. Direct blood type is the second most common type of blood in the world. As the second most common blood type, A + can be found in 34 people out of 100 people in the world. Some statistics show that the exact type of blood can be obtained by one-third. Generally, this means that about 36 per cent of people have an A + blood type. Although the numbers are high, by nationality, the numbers of those who participate in this blood type are not the same. For example, in Africa, only 24% of people have A +, in Spanish countries that number is high (29%), and in Asia, we have 27% of people with good blood.

Asset patterns A +

The gene known as ABO is found in chromosome 9 and is used to establish a blood group system. In this gene, A and B are closely related. Note that people in group A have antigen in their blood and antibody B in their plasma while those in group B are negative. There is a specific pattern followed by blood groups, and it is used to determine the continuous path of the blood group. My patterns are as follows: An interesting fact about blood type A + is that a child will have a blood group or blood group O if their parents have group A and O. But if a child has blood type A or B, it means that one of his parents has an O and the other has an AB group. On the other hand, if both parents have group A, the child will have blood type A or O. If one parent has group A and the other has group B, the child will inherit A, B, O, or AB. However, a child will have A, B or AB if his or her parents have A and AB blood groups. And finally, if both parents have AB blood group, the child will have group A, B or AB.

Acceptance of compliance: A + can only receive blood: A +, A-, O +, and O- The reason why a person with a good blood type receives blood in certain groups only is that A + has antigen A in red cells. People with this antigen in the blood can get blood from people with the same antigen (in this case, A + and A- blood types), and they can get blood from the universal O group (both good and bad). All other transfusions, such as blood transfusions in group B, can cause the immune system to develop and have serious side effects.

Donation Agreement: A + can only donate blood to people with blood groups A + and AB +. Although it can receive blood from both A and B blood types regardless of + or - signalling it, a person with A positive blood type is the only corresponding donor of those with Rh factor present in their blood and A-antigen. These interesting facts about blood type A + limit the number of those who can receive blood from an A + donor and do not include those with blood types A + and AB +. Note that blood can be renewed after 56 days.

Plasma type relationship: find A and AB, give O and A. Since A is a blood group that does not have antibodies A, it can get plasma from blood groups A and AB. On the other hand, as a donor, a person with type A blood may donate plasma only to those with A or O. Note that the same person may donate plasma after 28 days.

A +, the presence of Rh Factor: We have already listed Rh Factor. It can be described as one of the additional symptoms found in blood, and it can be either good or bad. The primary purpose of the Rh factor is to determine genetic variation. When it comes to blood type A, it has an Rh-positive factor. An interesting fact about good blood is that it is thought that people with blood type A + have an increased risk of certain diseases such as diabetes, various heart diseases, all kinds of allergies and more. That is why it is highly recommended to keep track of these situations and to pay close attention to them. Different strategies can be used to prevent and achieve lifelong success.
