Where is a person's blood type recorded

An individual's blood type cannot be found online. To find out your blood type, you can go to the hospital and have your blood drawn for a blood type test.

Blood type can be tested by taking blood from a hospital. There are two blood type systems commonly used in clinical practice, the ABO blood type system and the RH blood type system. The blood type can be detected through laboratory tests, and the operation is relatively simple. Just take blood from a peripheral vein, and the results will be ready in 20 minutes.

The four most common blood types are A, B, AB, O, and RhD positive blood. RhD-negative blood is the least common blood type. There are dozens of typing systems for human blood types, and the two main typing systems are ABO blood type and Rh blood type. They are currently used for clinical blood typing as well as for transfusion of blood products.

Methods to determine your blood type:

Methods to determine your blood type include taking a blood type test, checking your health records, and speculating based on your parents' blood type.

1, blood type test: you can go to the hospital or professional testing organization for blood type test. The test is divided into two methods, one is the ABO blood type test, analyzing the antigen on the surface of red blood cells for identification; the other is the Rh blood type test, testing the RhD antigen on the surface of red blood cells.

2. Check your health records: blood type information is usually recorded in your health records, and you can look for documents containing your personal health records, such as your enrollment physical examination report.

3. Parent's blood type: Based on the blood type of your parents, you can deduce the range of your own possible blood type. However, this method does not give you the exact blood type and can only be used as a reference.

It is important to note that using a home kit to test your blood type on your own may have errors and is not as accurate as the results from a professional testing organization. If necessary, it is recommended to go to a regular medical institution to have your blood type tested.
