Yup. O- is the universal blood type and the one that is in shortest supply. It can be given to anyone and is used in emergencies where there is not enough time to test the blood type of the patient. The downside is that O- people can only have O- administered to them. So all you O- guys and gals, get out there and donate (like my DH) because you never know when you might need to save yourself or your loved ones and others.

P.S. 80% of us will need blood at some point in our lives, but only 4% of NZ donate.

Hi Flair, you might like to open a new thread so everyone sees it again.

Oh and if you are less than 12 weeks into a continuing pregnancy (ie. you are not miscarrying) you generally don't need to have it as it is your blood rather than the babies that you are spotting, altho some LMC's would do it anyway as routine procedure after any bleeding. I never had it after my first two lots of spotting with the gremlins in the first tri.
