"The April rain, the April rain,
Comes slanting down in fitful showers,
Then from the furrow shoots the grain,
And banks are fledged with nestling flowers;
And in grey shawl and woodland bowers
The cuckoo through the April rain
Calls once again."

Mathilde Blind, April Rain

Transforming all donated blood into a universal type

science24science24 Posts: 987 ✭✭✭✭✭
Every day, thousands of people need donated blood. But only blood without A- or B-type antigens, such as type O, can be given to all of those in need, and it’s usually in short supply. Now scientists are making strides toward fixing the situation. In ACS’ Journal of the American Chemical Society, they report an efficient way to transform A and B blood into a neutral type that can be given to any patient.

    O positive is the universal donor isn't it? But isn't this also the most common blood group @science24 ?

    O negative is the universal donor @mheredge. As it can be donated to all the positive and negative blood groups. Whereas, O positive can only be donated to all the positive blood groups not to the negative ones. Am I right @science24?

    I was always lucky, @science24; that mistake never happened to me. :)

    You are right @mheredge it is the most common blood group, but as @Dora mentioned it might not be given to Rh negative blood patient, so the universal blood donor is O negative, though it's not as popular as O positive is, for that some ppl like to call O+ the universal blood donor for that abundance.

    lucky you @april but the new generation don't have to worry about that anymore

    I'm not sure if we can do anything about making all blood donated universal. Surely matching the blood type is preferable?

    Universal donors will be converted into global donors then. :)

    I'm not sure if there are blood banks everywhere yet @Bubbly. Certainly there aren't many in Nepal and there are often appeals to friends and relatives who share the same blood type as the patient needing blood. I try to donate blood whenever the opportunity arises.

    @mheredge I dont even know my blood type but I am curious to know it. I can't donate blood because of diastolic BP.

    @Dora is right and always a problem happened with people who have a negative blood but now there is solution for that

    It would definetely prove useful, more people would be cured and a way faster, don't have to wait until a person with appropiate blood type will be found

    We have to follow the same rules in kidney transplantation while the rhesus negative or positive don't have no importance. We take attention only on ABO system.Few years ago doctors developed a new methods that allow to person who's A to receive an organ from person who's B and vice versa.This method can eject B antibody from the A blood after this he became neutral and he can receive a kidney

    if this new technology hasn't any side effects it would be helpful in rescuing the life
    of millions of people around the world :smile
