Let's say your name is Gilligan, you've survived a shipwreck and you're stranded on a desert island. You happen to have been stranded with a medical doctor that has a limited stock of medical supplies. One of your shipmates is in desperate need of a blood transfusion but doesn't know his blood type. You do know your blood type. How could you type his blood with your knowledge and limited medical supplies?

Answer:

In order to find the blood type of the shipmate, Gilligan mixes a little blood of the shipmate with himself firstly and than with individual blood types to simplify the data by process of elimination.

Explanation:

There are a total of four types of blood groups which are as follows:

  • A blood grp has anti B antibodies, has A antigen
  • B blood group has anti A antibodies, has B antigen
  • AB blood group has no antibodies, has A and B antigen
  • O blood group has no antigens, has anti A and anti B antibodies

In order to find the blood type of the shipmate in the deserted needs of a blood transfusion, mixing of your blood with some of his blood is carred out:

  • if no clumping seen then the shipmate has same type of blood group as you or has AB blood group (AB has no antibodies).
  • If clumping is seen then person has O blood group(has both anti A and anti B antibodies) or the other type of blood group (that is if Gilligan's blood group is type B, if clumping is seen then the other person's blood group is O or A type because he has anti B antibodies in both of them)
