How do I know my blood type without analysis?, as blood is an essential component of the circulatory system, which also includes the heart and blood vessels, and the function of blood is primarily concerned with delivering oxygen and nutrients to the cells of the body, as well as getting rid of waste and carbon, and in this article on the website Reference The question will be answered, and the discussion will also be addressed about how to know the blood type through analysis, the systems for determining blood types, the characteristics of each blood type and the methods of blood transfusion.

blood type concept

Although everyone’s blood is made up of the same basic parts, there are actually a variety of blood groups, with eight different blood types, and their type being determined according to your parents’ blood type. This means that the subject is related to genetic characteristics, and it can be said that most people have about 4-6 liters of blood in their bodies, and blood is made up of different types of cells that float in a fluid called plasma, and red blood cells deliver oxygen to the various tissues of the body and remove carbon from Body tissues, white blood cells destroy invaders and fight infection, platelets help in the process of blood clotting, and blood plasma is a liquid made of proteins and salts, and what separates one person’s blood from another person’s blood is the unique mixture of protein molecules called antigens and antibodies Antigens live on the surface of red blood cells, and antibodies live in the blood plasma.[1]

How do I know my blood type without analysis?

In fact, there is no specific way to know your blood type without a test, but a simple and simple home test can be done by piercing your finger with a small pin and placing a drop of blood on a special test strip, then placing the test strip. The blood is on the strip, and the areas through which the blood is circulating can be traced and the results compared. The personal characteristics or some characteristics possessed by each type, and the following statement about this:[3][2]

• Stomach cancer is more common in people with type A than in types B and O.
• Blood type A, mosquitoes are not attracted to them like other blood types.
• Type B blood contains 50,000 times more beneficial bacteria than type A or O blood.
• Blood type B increases the risk of heart disease by 11% more than type A blood.
• Women with type AB or B have an increased risk of developing ovarian cancer.
• Type AB+ increases the risk of heart disease compared to type O by up to 23%.
• Type O can transmit red blood cells to anyone.
• People with blood type A are resourceful, serious, patient, responsible and rational, but they are usually stubborn and tense.
• People with blood type B are emotional, energetic, creative and strong in character, but they have selfish, irresponsible and curious personality traits.
• AB blood people are cold, rational and adaptable, but are often described as clumsy and irresponsible.
• People with group O are characterized by self-confidence, willpower, quick intelligence, and workaholics.

How do I know my blood type through analysis?

A person may not think that blood type tests are important if they have any health problems. According to the classification of blood type, a blood transfusion can threaten a person’s life if the wrong blood type is given, so it is necessary to study the blood type of the person who donates blood to him, as well as the blood type of the donor in order to know whether there is compatibility between them, in addition to the importance of examining the woman’s blood The pregnant woman to find out whether she is Rh negative or positive, in addition to the health care providers testing the blood type before transplanting the organ or donating an organ to transfer it to another person, and the blood type can be found in several ways using the analysis in one of the specialized medical laboratories, and the methods of analyzing blood groups are In the following:[3][2]

Glass slide method

One of the traditional methods is after blood sampling, where the specialist places two drops of blood: one to the right of the antigen solution A, and the other to the left of the antigen solution B. Then, he applies a drop of test blood to each solution on the slide if it collects with solution A, but It didn’t happen in B then it would be blood type A, but if it clustered with solution B, but didn’t happen with A, it would be blood type B, but if the two solutions clustered together it would be AB blood type. But if a clot does not form in any of the solutions, the blood is type O and a drop of blood is added to the third point, which can be used to determine the Rh factor in the blood, Rh positive in the person, and it is added to his blood type with a negative or positive sign.

How to find out your blood type at home

There are many devices and tools that are sold to determine your blood type from home, and they are easy to use for those who are not familiar with the details of the laboratory and the medical methods used in the laboratory and others who use a method similar to laboratory tests by wounding the tip of your finger with a medical scalpel and putting a few drops on a special card that comes with Your home test kit, or it can be liquids placed in medical tubes to identify areas where blood is circulating or accumulating and matching it with a special guide to reading the result that comes with the device itself.

How to check the blood type that is not taken

There are many tools for blood type without using a sample of the blood itself, where 80% of people excrete blood type antigens with other fluids inside the body, such as: secretions of saliva, sweat or mucus, and there are many of these equipment that are used to determine blood type using a sample of saliva, but it is expensive compared to other methods used.

Blood group features

Experts use the ABO blood group system to refer to the types of antigens present in red blood cells and the types of antibodies found in blood plasma, and researchers generally use the ABO and RH blood group systems to identify blood groups or groups that may be compatible together in a transfusion Blood varies from person to person. For another, and in general there are four blood groups belonging to the ABO blood group system, which can be mentioned and their characteristics as follows:[3]

• Group A: The surfaces of red blood cells in this group contain type A antigen, while the plasma contains B antibodies, which can attack any exogenous B antigen.
• Group B: The surfaces of red blood cells in this group contain B antigen, while the plasma contains type A antibodies, which can attack any exogenous type A antigen.
• Group AB: The surfaces of red blood cells belonging to this group contain B antigen and type A antigen, while plasma does not contain type A or B antibodies, so people with this group can receive blood from any blood type or blood group .
• Group O: The surfaces of red blood cells belonging to this group do not contain type B or type A antigens, but the plasma does contain type A or B antibodies, which means that a person with this group can donate blood to anyone.

Blood groups and their distribution ratios among the population

Some red blood cells contain what is called Rh antigen, which means that blood cells that contain this antigen can be described as RH, and blood cells that do not contain this antigen can be described as RH negative, and finally this question prompted experts to integrate the blood type system RH with the ABO blood group system in order to finally obtain eight blood groups that differ according to the proportions of their distribution among the population in the United States of America, which are as follows:[3]

• Blood type A+: It is estimated that about 30% of the population has this type.
• Blood type A-: About 6% of the population is considered to be a carrier of this blood group.
• Blood type B+: It is estimated that about 9% of the population has this type.
• Blood type -B: Only about 2% of the population is believed to have this type.
• Blood type AB+: Only about 4% of the population is believed to have this blood type, and a person with this blood type is called a joint recipient because they can get blood from all people regardless of blood type, due to the lack of AB blood type + Blood cells for type A, B and Rhd antibodies.
• Blood type AB: This blood type is the rarest of the blood’s virtues. The proportion of speakers is not more than 1% of the total population.
• Blood type O+: It is estimated that about 39% of the population has this type.
• Blood type -O: About 9% of the population carries this blood type, and a person who carries this type is called a common donor due to his ability to donate blood to all people regardless of their blood type, and this is due to the lack of blood type O blood cells for antigens from the groups A, B, and Rhd.

It should be noted that the above coefficients are not constant for all countries and regions, as in India, for example, blood type B + is the most common, while blood type A is most common in Denmark, and the proportions vary among the ethnic American population, for example For example, people of Asian ethnicity predominate in the presence of type B+ in a greater proportion than people of Caucasian or Latin American origin.[4]

How is blood transfusion?

Blood is transfused according to the type of blood type, and it is better for the donor and the recipient to have an optimal match between the two blood types for both, but in most cases there is no need to match the two blood types. But compatibility between them is important, because each blood group has its own advantages, other blood types can be donated and recipients of others according to these characteristics, the following groups are not allowed from each other and groups that move between them:[4]

• Blood type O: Derived from blood type O only.
• Blood type A: which comes only from type A or O.
• Blood type B: It is transmitted only by type B or O.
• Type AB: The one who receives from A, B, AB, or O.

What does blood type depend on and is it hereditary?

Human blood groups are determined according to genetics; Since every person inherits genes from his parents, he inherits a gene from his father and a gene from his mother, and accordingly his blood type is determined according to the following:[5]

ABO system

Sometimes a person inherits A antigen from one parent and then inherits B antigen from the other, so his blood type is AB, while he can inherit B antigen from both parents, so his blood type is BB, and on the other hand, blood type O does not contain any antigens; Which explains the no effect on blood type A and B, which means that if a person inherits from his mother O and inherits from a father with type A, then his blood type will be A, and parents with blood type A or B can also have a child with type O if They had an O antigen, and parents with an AO blood type could pass the O antigen to their child whose blood type is OO or only O.

Rhetoric RH

A person’s blood type is also determined by the Rh factor; This is another antigen found in red blood cells, where if the cells contain this antigen, then the blood type is positive (ie, Rh factor positive), but if it does not contain this antigen, then the blood type is negative (ie, Rh factor negative). ); The different blood types are classified as positive and negative, as mentioned earlier, depending on the Rh factor.

Frequently asked questions about blood types

Common questions about blood types include:[5][6]

Can children’s blood type differ from their parents’ blood type?

A person’s blood type is determined based on the genes he inherited from his parents. He inherits a gene from his father and a gene from his mother.

Is blood type related to corona?

Some recent data indicate an increased risk of contracting Covid 19 (coronavirus) in people with blood type A, while this risk is reduced in people with type O, but these risks remain relative and vary from person to person.

Is the blood type diet a fact or a myth?

Over the past decade it has been widely believed that eating certain blood type foods reduces the risk of certain diseases (blood type diet), but there is no scientific evidence to support these claims.

How important is knowing your blood type?

Austrian scientist Karl Landsteiner discovered different types of blood in 1901, and doctors at that time believed that all people’s blood was the same, which led to the death of many people as a result of blood transfusions; Mixing two different blood groups leads to blood clotting and death, as the recipient’s antibodies attack the donor’s blood cells, causing a toxic reaction.

Finally, in this article, the question posed has been answered, how do I know my blood type without analysis? The discussion was also discussed about how to know the blood type through analysis, the systems for determining blood groups, the characteristics of each blood type and the methods of blood transfusion.
