The ABO blood group system was discovered by Karl Landsteiner in 1900. 46 year later (1946) the Blood Transfusion Service was formed. In 1996 the National Blood Service was formed to collect and provide blood supplies for all the hospitals in England and North Wales. We then merged with UK Transplant to create NHS Blood and Transplant.
8, 000 units of blood are needed every day to meet hospital demand. Blood comes in four main types - O, A, B and AB. Group O is the most common which means it is in high demand. Blood can also be subdivided into its main components - red cells, white cells, platelets and plasma. Unfortunately red cells only have a shelf-life of 35 days, while platelets shelf life is even less, only five days.
Almost anyone between the ages of 17 and 65 can become a new blood donor. And those who are regular donors can continue to donate as long as they are in good health.
Last year we collected 2.1 million donations from about 1.6 million donors. Although that sounds a lot, it reflects only 4% of the population, giving two or three times a year.
The average adult has around 5 trillion red blood cells in one litre of blood. Which means you have on average 25 trillion red cells running around inside you, although 25 million (or 0.1%) of them die every day. That works out at roughly 300 a second.
William Harvey was the first physician to discover that blood circulates round the body back in 1628. Sir Christopher Wren (St Paul's Cathedral Christopher Wren) actually injected fluids into the circulation of animals, using an instrument invented by the aforementioned Mr Harvey.
The first successful blood transfusion was carried out in 1665 by Dr Richard Lower. He used dogs as the donor and recipient. However, when they started performing transfusions on humans, they couldn't understand why the people receiving the blood kept dying. It wasn't until 1900 that Dr Karl Landsteiner discovered the ABO blood group system and realised that human patients needed to be given compatible blood. He got the Nobel Prize for his discovery.
46 year later (1946) the Blood Transfusion Service was formed. In 1996 the National Blood Service was formed to collect and provide blood supplies for all the hospitals in England and North Wales. We then merged with UK Transplant to create NHS Blood and Transplant.
The most important blood groups in transfusion are the ABO blood group system and the RhD blood group system.
Blood groups are determined by a protein (antigen) on the surface of the red cell. So, the ABO system has A and B antigens and the RhD system has the D antigen.
In all, there are 30 major blood group systems. This means a person may be A RhD positive, and at the same time Kell (Kell system) positive, M and N (MNS system) positive and Lea and Leb (Lewis system) positive.
The ABO blood group system
If you have blood group A then you have got the A antigen on your red cells.
Blood group B means you have the B antigen, while group O has neither, and group AB has both A and B antigens.
The ABO system has associated anti-A and anti-B antibodies, antibodies being the body's natural defence against foreign antigens. These antibodies are found in the plasma.
Blood group A has the A antigen. This group recognises the B antigen as foreign and can make anti-B antibodies.
Similarly, blood group B has the B antigen and therefore recognises the A antigen as foreign and can make anti-A antibodies.
Group AB has both the A antigen and the B antigen so this group makes no antibodies.
Group O has neither A nor B antigen so this group can be given safely to any other group. This is why Group O donors are known as ‘universal donors’. Group O can make both anti-A and anti-B antibodies if exposed to these antigens.
Giving someone blood from the wrong ABO group could be life-threatening.
For instance, the anti-A antibodies in group B attack group A cells and vice versa. This is why group A blood must never be given to a group B person.
Will Nascar recognized national organ donor day during the Daytona races?
If anyone hasn't registered for donating organs its a great program that helps others to live if when you don't. I have signed my license and have done so for years.
No need to ask what organ you will be donating Mongo/Rainbow (can't tell you two apart). Yes please wear a condom. Just remember to stick a checked flag in your partners ears. The next day is the Daytona 500.
