FYI

fyi

When I first started this blog, I had a calendar that listed random information.  I would compile it for each month based on what it said.  I also had a thing called trifecta of word, picture, and video.  While I’m not going back to the trifecta on a weekly basis, you will find it once or twice a month.  This is basically a page of FYI.  Knowing your blood type is important.  There are eight major blood types and their compatibilities is listed below.  Hopefully you already know your type.  If not, get tested.

4typesThere are four major blood types based on the absence or presence of antigens.  The two antigens are A and B.  The eight most common blood types are A+, A-, B+, B-, O+, O-, AB+, and AB-.  The universal red cell donor is type O- blood and the universal plasma donor is type AB blood.  While worldwide there is no standard rarest blood type, in the U.S. it is the AB- blood group and O+ being the most common.

Blood type O has neither A or B antigens on red cells.  There are A and B antibodies in the plasma. 

Blood type A has A antigen on red cells.  There is B antibody in the plasma. 

Blood type B has B antigen on red cells.  There is A antibody in the plasma. 

Blood type AB has both A and B antigens on red cells.  There aren’t A and B antibodies in the plasma.

O- blood can be donated to A+, A-, B+, B-, O+, O-, AB+, and AB- but can only receive blood from O- blood.

O+ blood can be donated to O+, A+, B+, and AB+ but can receive blood from O- and O+ blood.

A- blood can be donated to A+, A-, AB+, and AB- but can receive blood from A- and O-.

A+ blood can be donated to A+ and AB+ but can receive blood from A+, A-, O+, and O- blood.

B- blood can be donated to B+, B-, AB+, and AB- but can receive blood from B- and O- blood.

B+ blood can be donated to B+ and AB+- but can receive blood from B+, B-, O+, and O- blood.

AB- blood can be donated to AB+ and AB- but can receive blood from AB-, A-, B-, and O- blood.

AB+ blood can only be donated to AB+ but can receive blood from A+, A-, B+, B-, O+, O-, AB+, and AB- blood.
