blood group type O negative blood.
Answer From Rajiv K. Pruthi, M.B.B.S. For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it’s sometimes called the universal blood donor type.
Is O+ is a universal donor?
Although the blood type O+ can donate blood to all positive blood types (A+, B+, AB+, and O+), it is not a universal donor. Blood type O- is the universal blood donor, meaning that people with this blood type can donate blood to all other types with a lower risk of causing serious reactions.
Can O+ blood donate to anyone?
O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).
What is the rarest blood type?
AB negative
AB negative is the rarest of the eight main blood types – just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.
Why O+ is not universal donor?
About 43% of the population has type O blood, either positive or negative. O positive blood can’t be used universally because it has the Rh factor, but it is compatible with all positive blood types including O+, A+, B+, and AB+.

The main difference between O positive and O negative is that Rh factor is present on the surface of the red blood cells of the O positive blood whereas Rh factor is absent on the surface of the red blood cells of the O negative blood.
Is O Negative a rare blood type?
Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood.
What is special about O positive?
O-positive and CMV-negative blood type is the safest blood type that can be transfused to immunocompromised newborns. Although the O-positive people can donate blood to people with any positive blood type, they can only receive blood from O positive and O negative (O−) people.
Who has the golden blood type?
One of the rarest blood types in the world is Rhnull, sometimes referred to as ‘golden blood’. People with this blood type have a complete absence of any of the Rh antigens.
Can siblings have different blood types?
No, siblings don’t necessarily have the same blood type. It depends on the genotype of both the parents for the gene determining the blood type. E.g. Parents with the genotype AO and BO can have offspring with blood type A, B, AB or O.
What blood types should not have babies together?
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
Which blood type is rare O+ or O?
How common is O positive blood? O positive is the most common blood type as around 35% of our blood donors have it. The second most common blood type is A positive (30%), while AB negative (1%) is the rarest.

Marriage should be avoided in between Rh negative female & Rh positive male.
What is the oldest blood type?
In molecular history, type A appears to be the ‘oldest’ blood type, in the sense that the mutations that gave rise to types O and B appear to stem from it. Geneticists call this the wild-type or ancestral allele.
How do I find out my blood type without a test?
Without drawing blood
A person may be able to use a saliva sample to test for their blood type. Around 80% of people produce the relevant antigens in their saliva. According to 2018 research , if a person secretes these antigens in their saliva, a dried saliva sample can reliably indicate their blood type.
Can your blood type Tell your heritage?
Because blood types are genetic, they are inherited from the parents, blood types have different racial and ethnic differences. The majority of people in the world and across various ethnicities have Rh+ blood type. Subsaharan African populations have a 97-99% Rh+ factor. East Asian communities have 93-97% Rh+ blood.
