Donating Blood Types

Last time I talked about donating blood, plasma, and platelets. Well, after a little digging, I found out that the Australian Red Cross as preferences for what donations they would like to receive from you based on your blood type. This was funny to me because I didn’t know what my blood type was until like two months ago (I know, I’m so irresponsible). Turns out I’m O+.

A brief breakdown on blood types: there are eight types (four types, either positive or negative). The letters are the blood cell types, with O being the most versatile that all the others can accept and AB is the most accepting being able to take in all other types. Now, it gets a bit more complicated when we bring in the positive and negative aspect of blood types. If your blood has the D protein, you are RH positive, making your blood type positive. People without the protein (negative blood types) can only receive other negative blood types, but people with the protein (positive blood types) can accept both. To visually simplify all this, I borrowed the picture for this blog from the Australian Red Cross page on blood types.

Moving on. I don’t really have an explanation for why they have these listed, but I’m going to cover what the Red Cross prefers is donated based on blood types.

O+, A+, and A- can donate everything. So donate whatever you’re comfortable with. This is especially true for O+ which is the most common blood type, followed closely by A+.  

B+ and AB+ would be best donating plasma.

B- and AB- are good with whole blood and plasma.

And O- donors theoretically would be best to give platelets (if you’re a male).

Now, this is in no way limiting what you can donate; this is just what may be highest in demand for you blood type at the moment. Please, donate what you feel most comfortable donating.
