What are the occasional blood types?

Could someone give me a list of different blood types and how rare they are? I'm donating blood this Thursday and I'm simply curious

Be aware that the rhesus and ABO systems are not the only systems in use. There are also about 200 other antigen types found on red cell, major examples being Kell, la and rho. Some of these antigens are exceedingly rare.

For the ABO system coupled with the Rhesus system, there are 8 types. Assuming you are located in the US, the types and occurrence are as follows.

AB+ - 3.4%
AB- - 0.6%
A+ - 35.7%
A- - 6.3%
B+ - 8.5%
B- - 1.5%
O+ - 37.4%
O- - 6.6%

There is an even rarer type, Bombay blood, that cannot even receive type O, but Bombay type only. This type is very rare, and falls surrounded by the hh antigen system.

There are even rarer types that can complicate transfusions.
