Thing is eeg, when I say "ok" on the O type, stock currently in our bloodbanks, its not a static thing and fluctuates very quickly. If your O neg and been at least 12wks since you were last there, Id urge you to go if youre able. If You are O pos I would also urge you to go, as that is the most common blood type int he UK and that is the type which is needed the most. with B type coming next after that.....
The shelf life of blood or its components, isnae too long (it differs depending on what has been donated <not the blood type, the components/platelets etc>, before it starts to degrade, so the "fresher" the donation the better it is for the Patient.)
Literally every single donation that comes in is used on someone deperately ill. You may have specific components in your blood that can be taken from your donation which can specifically help eg cancer patients or babies. Also every single expectant mother has blood specific to them and their child ready, incase of any complications. All hospitals are unable to perform surgery unless there is sufficient blood stocks.
So if you are able to at anytime get yourself to your nearest Blood Collection, please do.
Apologies for the guilt laden post
