2.DNA detection methods
In a word, blood type test is a very important medical test, which is of great significance to blood transfusion, organ transplantation and marriage matching. When testing blood type, the examinee should pay attention to choose a regular medical institution for testing, and follow the doctor's guidance and precautions to ensure the accuracy of the test results and their own health and safety.
Serological detection refers to the determination of blood type through the reaction to the serum and reagents of the detected person. This method is mainly suitable for the detection of ABO blood group and Rh blood group. In this method, the doctor will mix the serum of the tested person with reagents of different blood types, and observe whether agglutination reaction or dissolution reaction will occur between them, so as to determine the blood type of the tested person.

DNA testing refers to determining the blood type by detecting the DNA sequence of the detected person. This method is mainly suitable for the detection of ABO blood group, Rh blood group, Kell blood group and other blood groups. In this method, the doctor will extract DNA samples from the blood of the subject, and then detect them by PCR amplification, electrophoresis and other technologies to finally determine the blood type of the subject.
