Often people start to think about their blood group in case of health problems. But a person must know such important information about himself and his family. When treated in a hospital, doctors will conduct this research independently, but in critical cases, where every minute counts, this information is extremely necessary. We will tell you how to determine the blood group at home.

How to determine the blood type
In addition to emergency situations, knowledge of the blood group and Rh factor is required to improve a person's condition. For example, when making recommendations on nutrition.
There are 3 main ways to know which blood:
- Fulfillment of analysis in the laboratory.
This method is considered the most effective. The study is conducted on a professional level with special equipment. The advantage of the method is to obtain an accurate result.
- Donation of blood.
This method is at the same time the most accurate and fastest. In addition, the surrender of your blood can help the sick.
- Conducting a study at home or blood group tests.
Without the necessary tests, it is very difficult to correctly establish the blood group, but the probability of an accuracy of the method of determination exists.
The advantage of the method is to exclude the need for a trip to the hospital. The only thing that is necessary is the knowledge of the theory in the field of biological sciences.
There is a special system of antigens AB0. The blood group is a special combination of antigens and antibodies of the ABO system located on the erythrocytes. Agglutinins are antibodies contained in plasma. With the help of them, group membership is determined. α-agglutinin is characteristic of the I and III group, and β-agglutinin for I and II. In red blood cells, antigens A or B can be contained individually, together or completely absent. Hence, there are 4 main groups:
- I group. It is characterized by a content in the plasma of 2 agglutinins.
- Group II is characterized by the content of β-agglutinin.
- Group III is characterized by the content of α-agglutinin.
- Group IV - agglutinins are absent.
The rarest group is the fourth. The most common are the first and second groups.
Rhesus factor (Rh) is an antigen, determined together with the blood group. It happens to be positive and negative.
Methods of conducting a study of belonging to blood groups without testing
The easiest way to find out where the group is written is to look at the information in your passport. Most people have a seal with the appropriate blood type and Rh factor. If there is no such data in the passport, you should look at the medical card.
In the statement from the card, the group characteristics must be indicated. Depending on them, you can determine the blood group. If 00 is specified, then you have I group; 0A, AA-II; 0B, BB - III and AB - IV. Rhesus factor is even easier to find out, at the top should be "+" or "-".
Remember!Only a specialized doctor will be able to correctly determine your group and Rh factor in the analysis of the tests.
How is the blood group and taste preferences of a person
Some experts put forward several theories about the effect of the blood group on the taste preferences of people.
According to the carried out researches they carried certain classes of products to each group. Thus, finding out what you most like, you can predict your data.
Representatives of the I group include lovers of meat products. For II - is characterized by a love of vegetables and various types of cereals. People who prefer dairy products are referred to as III. The representatives of the IV group do not have obvious taste preferences.
Blood type and psychology
There is an opinion that the blood group affects the character and ability of a person. Using this theory, you can compare your character.
A person with clearly expressed leadership qualities, a strict character, self-confident, is the representative of the first group. To the second, people are calm, quiet and peaceful. The third one - characterizes bright, eccentric and sociable personalities. The character traits of the fourth representatives are much more complicated, they are too versatile.
Important!These theories do not give a complete picture of the required question. The further use of information for medicinal purposes may harm your health.
How to recognize the blood group and Rh factor in a child
There is an opportunity to conduct research on belonging to a certain blood group before the birth of the baby.
Everyone knows that any person inherits genes from their parents. A similar situation occurs in the case of this analysis. To determine it, it is enough to know the blood type of the father and mother. In this case, after going through all the possible combinations, you can find the child's belonging to the group in a percentage.
As already mentioned above, for each group there are conventions. Using them, you can get the necessary information. Of course, not all cases guarantee a definition with 100% accuracy. But it is worthwhile to list possible combinations.
If both parents belong to the first group (00), the second (AA) or the third (BB), then the child will have the same probability with 100%. In cases where one parent has I (00), and the other has II (AA) or III (BB), then II (A0) or III (B0), respectively. The fourth group can be a child, one parent with a second group (AA), and the other with a third (BB).
With the Rh factor, things are much simpler. If both parents have a negative parent, then the baby will have a similar one. In other cases, it is impossible to predict the result.
Attention!If the father has a positive Rh factor, and the mother has a negative Rh factor, it is mandatory to consult a specialist.
Innovative methods for determining the blood group and Rh factor in the home
To date, scientists from Austria have developed a unique way of conducting home-based analysis, which will help quickly identify the blood group. They carried out a very serious work. The method presages not only obtaining the exact result, but also the simplicity of carrying it out as a whole.
To do this manipulation at home, you need only a small test strip and a drop of blood. Literally in a few minutes, the hands will have a ready result.
This innovation will avoid waiting for the analysis and the result in the hospital. Often time in this matter plays an important role.
Home test for Rh factor
Do not fall behind on innovations and experts from Denmark. Express cards developed by them, under the trade name Eldoncard, can significantly reduce the processing of this analysis. And they can be used in emergency situations in hospitals, educational institutions and at home.
The basis is improved types of "dry" monoclonal reagents. With their help it is possible to determine the antigens AV0 and Rh-accessory together and separately.
The analysis does not require specially trained personnel, laboratories and equipment. You need only water or fiz. solution.
The order of the research:
- In each circle with the reagent add a drop of water.
- Take the blood and apply it on a special wand.
- Apply to the map and wait 1.5-2 minutes.
Attention!After interpreting the result, it is necessary to apply a protective film to the test for its full preservation (up to 3 years).
Express test has a wide range of storage temperature. He passed numerous tests in various premises, in emergency situations, has certification in Russia.
In the end, if you are just curious to know your blood group and the process of research, then certainly follow the instructions given in the article. Otherwise, you should contact the medical institution for an accurate result. In any case, whatever reasons may be, to do some kind of analysis at home is entirely realistic!
