রক্তের ধরণ: বিভিন্ন রক্তের গ্রুপ কীভাবে পরীক্ষা করবেন

All of us bleed red – but of various types. It is common knowledge that blood can be classified into different blood groups; news scrolls and WhatsApp texts carry urgent requests for a particular type of blood and Facebook’s ‘blood donor’ feature caters to requests based on blood groups. Those of us who are a part of any social network that provides a conduit for blood to flow from person to person, know that the following blood groups (or types) exist: A, B, AB, and O. Also familiar to us, is the positive or negative sign that accompanies these basic blood types, further segregating them into eight groups. On what basis, then, are these divisions organised?

ABO Blood Types

• Blood group A has type A antigens (and type B antibodies)
• Blood group B has type B antigens (and type A antibodies)
• Blood group AB has type A as well as type B antigens (and no antibodies)
• Blood group O has no antigens at all (and both types of antibodies)
• (Antibodies are also protein molecules launched by the body to counter the effect of antigens.)

No prior preparation is required for a blood group test, other than the extraction of a blood sample. Any diagnostic centre will have a laboratory equipped to perform the test on this sample, but it is always safer to consult an established and reliable organization.
