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 wonder what the shelf life of donated blood is?
i hear you got the machine that goes PING!
Can't donate blood coz I feel very weak afterwards
I don't know why, but I was really fixated on that little cradle machine that agitates the blood to stop it coagulating. lol
i am 0 res negativ and i have sleeping lyme borilliosis with antibodys under the threshhold can i still donate?

I think all potential receivers of your blood would appreciate if you pose this question to a competent doctor and not a KZread comments section :-).

You don't need gloves for a blood transfusion.
Unfortunately Secondary Polycythaemia stops me from donating.

I have polycythemia vera, which means I must periodically "donate" blood that must be discarded. That's right. It is treated with blood-letting. No cure. I have asked RI to do a video on the JAK2 gene, which is the one that mutated and caused the disease. So far, no response.

Indeed I have Secondary Polycythaemia to Testosterone HRT from at Atrophied Pituitary Gland Posterior Lobe. Had the gene tests (JAK2, and 8 others, 'normal' from Genotype) and 3 Bone Marrow Biopsies were all negative. So, like you, no 'cure' other than to stop the Testosterone (which means I basically stop functioning as a 40 year old and become like I 90 year old, so not doing that !). Good idea to ask them to do a video, would be very worthwhile; notably my GP said that many men don't get a proper diagnosis as this sort of thing is often missed or mis-diagnosed. Hope you get a response.

Her blood doesn't look very oxygenated.

That's because it's coming out of a vein. Venous blood is returning to the heart and has already given up its oxygen, so it is much darker than arterial blood.

freshoutofcrabs Right. I forgot that's returning to the lungs, so it will be deoxygenated thus having a darker color.
wish they did a better job nice try though
