How many of you have donated blood at least once?

Lot of information on blood groups.. I am universal donor(O+) but never got chance to donate... :P :)

Just wanted to add that even though people with O blood group are called universal donor, The real Universal donor are people with O- blood groups for they can donate to person of any blood groups while the people with O+ blood groups can donate only to people with O+, AB+, A+ and B+ groups.

Can O- people donate blood to positive groups? :unsure: :unsure: :unsure:

I learnt in school that......it does not harm for the first time when positive group people is given negative blood group and vice versa . But the real problem occurs when second time blood is donated.
i.e. When blood is donated, they produce corresponding antibodies that time will surely harm the second time blood is donated.
I think positive groups produce negative antibodies and negative groups produce positive antibodies which will react second time, when any of the blood group is donated...... i.e. When both type of antibodies are present in our body, it will fight against the antibodies next time. Sheetal, am I right? :dry: Am quoting it from my memory. Just add missing factors please

Yes sandhya you are right somewhat.. O-ve can donate blood to all the blood groups but can receive blood only from O-ve donor and thats y people with O -ve blood group are called as universal donor. Since O blood group do not have antibodies and antigens against A or B . Hence they can donate blood to any blood groups. I hope your doubt is clear now. By the way ur memory is good...U still remember correct things.

Sheetal could you also please explain about what sandhya had said that there is no problem when negative blood group is donate to the positive blood group people for the first time and vice versa and that the problem arise when it is donated for the second time. Actually, I read somewhere that problems can arise from the first time itself.

Yes we cannot donate the -ve blood group to positive not even first time also.
Only Rh-ve can donate blood to Rh +ve because Rh-ve do not have antigens in their plasma. But Rh+ve cannot donate blood to Rh-ve as Rh+ve would have specific antigens in their blood plasma.

Are blood group with Rh-ve and negative blood group different things? I thought that they were same. So, I find your sentences contradictory. could you please explain the differences?

Rh -ve means negative blood group and Rh+ve means positive bld group . they are the same.

Positive blood group, found in Rhesus Monkey...Rh factor :P
So, all positive group people including me are :laugh: :laugh: :laugh: :laugh:

Rh -ve means negative blood group and Rh+ve means positive bld group . they are the same.

In reference to your previous post, in the first sentence you said that we cannot donate negative blood group to the positive blood group people from the first time itself. Then in the second sentence, you said that Rh-ve can donate to the Rh+ve because Rh-ve do not have antigens. And if the meaning of Rh-ve and negative blood group are same, then your second sentence is just the opposite of what you said in the first.I mean first saying cannot donate, then saying can donate.... Am little confuse

Ya..Sheetal should clear it. I also have the same doubt...even donating blood, first time....

wow :woohoo: , there are so many useful information about blood groups. Lets wait for Sheetal's final answer for blood group confusion. :dry:

Vinodh we all must know this information as it is useful some times to us and others.

Sheethal, where are you???

As this is weekend he is enjoying with his wife so he is out of the site.

Sheetal..I want your answer
Please clear my doubt.

Sheetal has gone to collect your answer,wait for some times.

I have donated blood for at least 20 times as this was par of our corporate culture. We did it every year.

I donated blood only once.And my blood group is 'O' positive. My husband group is also o+. :) :)

I did not donate my blood before. My blood group is b+ :silly: :silly: :silly:

I never donated my blood in my life. I feel i have less hemoglobin so it is not much good to donate

I have got many opportunities to donate blood.But Icannot donate because my health does not permit to donate blood.

What is the problem? :blink:

Are you under weight? :blink:

Sj, there will be many causes, if the hemoglobin is less, if we have BP, or any blood related problems we cannot donate blood

I want to donate blood but due to my health problem I could not donate blood to anyone.

I like to donate blood.I think that if I could donate it then I can save any body's life.But due to some problem I cannot do so.
