Chromosome 9 - It's in the blood

Blood transfusion used to be a hit & miss affair, until the discovery of blood groups. The group most people have heard of is the ABO group, controlled by a gene on Chromosome 9 as explained by Nicole Thornton. This gene controls what blood type you are - whether A, B, O or AB. However, there are actually over 30 other blood group systems, most of which are extremely rare.

Nicole explains the consequences of receiving blood from the wrong blood group as she chats to Olympia Brown, who learns what blood group she is when giving blood, and how important it is that as many different people donate blood, the first stage in the blood transfusion process.

Donated 12 times now, never had any adverse reactions or dizzy feelings. Everyone should give it a try!

arg >< looks like I'm just going to just listen to this one, though I've had to had my blood taken many times due to illness I still can't stand watching.. it's so bad when I do it I have to have it in the back of my hand or I freak out.

I don't know why, but I was really fixated on that little cradle machine that agitates the blood to stop it coagulating. lol

[Missnaughty]

Can't donate blood coz I feel very weak afterwards
