It's necessary to match the donor and recipient blood types to prevent hemolysis (destruction of red blood cells), clot formation, renal failure, and death. If blood types are incorrectly mixed, the antibodies of one may attack the antigens of the other.
For example, type A blood contains A angtigens on the surface and anti-B antibodies. Type B blood contains B antigens on the surface and anti-A antibodies. If type A blood is donated to a recipient of type B blood, the recipient's anti-A antibodies will attack the type A's A antigens. Red blood cells will be destroyed and the host's body will develop blood clots, release toxins that will result in death.
Type O blood can generally be given to anyone. It's known as the "universal donor" because it contains A and B antibodies but NO antigens. The recipient's body will accept the blood. However, type O blood can ONLY receive type O blood. Otherwise, it's anti-A and anti-B antibodies will attack the received blood.
Type AB blood can generally receive any blood type. It's known as the "universal recipient." Type AB has both A and B antigens but no antibodies. Therefore, it accepts any antigens. However, type AB blood can only be donated to another person of type AB blood. Otherwise, the host's anti-A and/or anti-B antibodies will attack the A and/or B antigens of the AB blood.
This was just a basic summary, and didn't take into consideration the Rhesus factor (positive and negative blood types).
There are 30 blood types recognized by the International Society of Blood Transfusion.
Have a great day.

∙ 14y agothis happens because the donor may have HIV or any other blood disorder or disease. this is only to protect the people getting the blood put into them.

Can you donate blood if you were an IV drug user?
You COULD, but traces of the drug would be transferred over to the donated blood. I don't know if the donated blood is tested for it, but the medical personnel doing the collecting would definitely be told to watch out for donors like that, and to turn them away.

When did they start testing blood transfusion recipients or givers for HIV?
Blood banks and hospitals did not test blood for HIV and AIDs before a test was invented in 1985. Now, all blood for transfusions and other purposes are tested before being collected. Prior to 1985 it was not possible to test blood donors or donated blood for HIV. In that year Robert Gallo of the NIH developed a kit which allowed the testing. Later the Louis Pasteur Institute sued and got half the rights to the invention.
How do people acquire the HTLV-1 virus?
The common routes of transmission are through breast milk, transfused blood (especially prior to 1989 when donated blood was not tested for HTLV-1), sexual intercourse, and drug injection.
