Determination of blood groups - Physiology practicals

We all should be aware of our blood groups. It plays a very important role when it comes to having a blood transfusion. Knowing our blood group helps us to select appropriate blood for transfusion either during any emergencies or accidents.

Here is a simple and easy experiment to find out our blood type sitting at home with the help of a Blood Group Test Kit.

A human blood cell includes red blood cells, white blood cells, and platelets. All these blood cells play a significant role in transportation, protection and regulation. Blood groups are mainly determined by the presence or absence of antigens and antibodies on the surface of our red blood cells or erythrocytes. Both antigens and antibodies are the protein molecules which functions as the body’s natural defence. This is the reason blood transfusion from the wrong blood group can be life-threatening.

The four major blood groups are: A, B, AB and O. The blood grouping system was discovered in the year 1901 by Karl Landsteiner- an Austrian biologist and immunologist.
