The process of blood group detection with a blood test
Now it is time to talk about the process of blood group detection with a blood test
To determine the blood group, a blood sample is needed. The test that is done for this purpose is called "ABO typing". In this test, the blood sample is combined with antibodies against A and B blood samples. If the cells stick together and the blood clots, it means that the blood has reacted with one of the antibodies.
The second stage of the test is called "reverse typing". In this step, the liquid part of the blood (serum) that does not have cells, is combined with bloods whose types are already known (A and B). People with blood group A have anti-B antibodies in their blood serum. People with blood type B have anti-A antibodies. Blood group O contains both types of antibodies and clots in both combinations. Example: If your blood plasma forms a clot when it comes in contact with blood group B (containing Anti-A), it means that your blood group is A. These two steps can accurately determine the blood group of each person. In the next step, your blood is combined with anti-RH plasma. If your blood cells clot in response, that means your blood type is positive (RH+) and if no clot is formed, your blood type is negative (RH-).
Important points before the test
Before the test, keep the following points in mind Have:
- The blood group determination test does not require any special preparation, and there is no restriction on food and drink consumption. But it will be resolved soon.

- This test is not particularly risky and you may only feel a little dizzy after the blood sample is taken. Blood
Red blood cells may or may not have another antigen called RhD. If this protein is present on the surface of the blood cells, the person's blood group is RhD positive, and if it is not present, the blood group will be RhD negative.
It is interesting to know that most of the population has a positive blood group. It is often possible to infuse all people with blood type O-. For this reason, this type of blood is usually used in medical emergencies where the patient's blood type has not yet been determined.
This type of blood is safe for everyone because it does not have any A, B or RhD antigens on the surface of the red blood cells and is compatible with all other blood types in the ABO and RhD systems.

- If the blood clots in contact with antiserum A or B, it means that your blood type is A or B. If both antiserum A and B cause clotting, your blood type is AB. But if none of the two clotting reactions show, your blood type is O.
- Finally, check the reaction of the third drop. If no clot is seen in contact with the Rh antiserum, your blood type is negative, and if a clot forms, your blood type is positive.
