Furthermore, determining blood type can be done using the ABO method. However, the ABO method does require a blood test as a preliminary step. By using this technique, the test results will classify the blood types into 4 categories: A, B, AB, and O.

When blood is dropped onto a surface that has been treated with anti-A substance, the blood type is determined as follows:

- If the blood clots on the surface with anti-A substance, the blood type is A.

- If the blood clots on the surface with anti-B substance, the blood type is B.

- If the blood clots on both surfaces, the blood type is AB.

- If the blood does not clot on both surfaces, the blood type is O.

4. How to Determine Blood Type with Rhesus

Same as the ABO method, the rhesus method will also be carried out together with blood type testing using ABO. The doctor will identify the rhesus (Rh) blood of a person. This is done by mixing antigen D and a blood sample. After that, the rhesus type will be determined.

- Rhesus positive (Rh+), if there is Rh antigen in the red blood cells. People with Rh positive can receive blood transfusions from individuals with Rh+ and Rh-

- Rhesus negative (Rh-), if there is no Rh antigen in the red blood cells. People with Rh negative can only receive blood transfusions from individuals with Rh- as well.

Those are some ways to determine blood type even without testing. To obtain accurate results, it is advisable to undergo medical tests to confirm your blood type. Hope this is helpful.
