Blood groups......?

Question

Can you tell me the blood groups according to their rarity.Which is the universal donor,O- or O+

Answer 1

i think  ,  usually  o+ is the universal donor.   we must help people who are wanting blood. its my kindly request.

Answer 2

0+ is universal, because everybody + can take it.  The least universal would be analogically AB-, AB is quite rare anyway.

Answer 3

o is best donor and worst aceptor  but o+ is best donor to all posetive blood group and o negative is donor for all negative blood group .Cross-matching for the RhD antigen is extremely important, because the RhD antigen is immunogenic, meaning that a person who is RhD negative is very likely to make Anti-RhD when exposed to the RhD antigen [perhaps through either transfusion or pregnancy).

Answer 4

O- is a universal donor

while AB is the universal recipients

O negative is also vitally important for specialized procedures, like giving an unborn baby with a blood disease a transfusion in the womb. It can also help prevent brain damage in a newborn baby suffering from jaundice. And it's the blood used most frequently for patients receiving bone marrow transplants.

Answer 5

o+

Answer 6

For the ABO blood grouping system:

The groupings are in order of most common first:

O+ ,O-, A+, A-, B+,B-,AB+, AB-.

O- s the universal donor.

Hope  this helps!

Answer 7

O is the most common blood type worldwide, though in some countries A is slightly more common. B is significantly less common, and AB rarer still. Rh+ is significantly more common than Rh-. The percentages of people by blood type worldwide are roughly:

O+ 38%

A+ 34%

B+ 9%

O- 7%

A- 6%

AB+ 3%

B- 2%

AB- 1%

O- is the universal donor type. That's because it contains neither the A or B antigens (which is what the "O" bit means), nor the Rh  antigen (which is what the "negative" bit means). O+ is NOT the universal donor type because it can't be given to people who are Rh negative - their body would have a haemolytic reaction to the unfamiliar antigen. However, it is usual to test the recipient's blood for compatibility before a transfusion is given - though the ABO and Rh antigens are the most important factors in matching blood types, other antigens can occasionally cause problems for the recipient.

Answer 8

O+ is universal donor

most rare blood group is AB group

and least rare is B+

Answer 9

from most to least:

O+, A+, B+, O-, A-, B-, AB+, AB-

but this varies slightly between each country. for example about 9% of the population in Aussie have the O- blood type, but there are virtually no people with any negative blood types in China
