Why does DayZ use the ABO Blood Type system? Wouldn't they be using Jan Janský nomenclature?

I work in healthcare and today I was thinking about Blood and Rh Factors.  At lunch, I thought about DayZ and thought about the I,II,III,IV nomenclature by Czech serologist Jan Janský and wondered why blood typing isnt using that based on the location.

 

Wikipedia: http://en.wikipedia.org/wiki/ABO_blood_group_system#History_of_discoveries

 ...Czech serologist Jan Janský had independently pioneered the classification of human blood into four groups.

Janský's nomenclature is however still used in Russia and states of the former USSR, in which blood types O, A, B, and AB are respectively designated I, II, III, and IV

 

So what does that mean? The fact that we have US flags on the tactical shirts, M4's, and ABO blood typing, does that mean we're not indigenous people? Are we Americans, who for whatever reason, were on mission to Chernarus (perhaps aid? UN directive?), and have lost consciousness only to awake without equipment or memory somewhere on the coast.
 
Perhaps we are civilian contractors with the UN and US forces who's ship capsized and now we have washed up on shore, regained consciousness, and now must try to survive?
 
I'm reading way to far into this.
 
TLDR: Shouldn't I be 'Blood Type I Rh +' instead of 'Blood Type A+'?

Hm, it has to be one system. And I think there are like 20 or so around the world? Tell me if I'm wrong. Besides that I love my 0- :)

I solved the mystery. I win.

That is the funniest thing I'll hear all day. Beans

Oh I thought that Rh means something different. I didn't know there were other systems.

The main system is the ABO system.  The Rh factor is the + and - blood type.

 

Czech serologist Jan Janský came up with the I,II,III, and IV types almost 20 years before anyone else.  It is still used in Russia.  <-- This is why I figured it would be so appropriate for DayZ.

 

Why we dont use it?   Well a similar nomenclature was created by William Lorenzo Moss three years later.  He had no knowledge of Janský's work as it was a few years before the internet. With his classification, the I and IV were opposite of Janský's.  This caused a lot of confusion which meant people were getting wrong blood type transfusions.  This was one of the main proponents to ABO becoming standard.

So... Is said activity with dolphin the cause?   Are you patient zero?

While I agree with it in an immersion sense.  I think the system used is universally understood thus making it functional across the board.  As to a main story addition, no clue.
