O-negative ( 𝑂 − 𝑂 − ) blood is generally considered slightly more rare than A-negative ( 𝐴 − 𝐴 − ) in many populations, or they have similar, low scarcity. While approximately 7 % 7 % of the population is 𝑂 − 𝑂 − , 𝐴 − 𝐴 − is found in roughly 6 % – 8 % 6 % – 8 % of the population. Both are significantly rarer than positive blood types but crucial for donations.
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).
Most Rare Blood Type
A positive: You can receive blood that's A positive, A negative, O positive or O negative. A negative: You can receive blood that's A negative or O negative. B positive: You can receive blood that's B positive, B negative, O positive or O negative. B negative: You can receive blood that's B negative or O negative.
While the Bible doesn't mention Jesus's blood type, scientific analysis of relics linked to him, like the Shroud of Turin and Eucharistic miracle samples, consistently shows Type AB blood, a rare type, leading some to believe it's a miraculous sign, though skeptics point to potential bacterial contamination.
O negative is the universal blood type. O negative blood type can only receive O negative blood. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.

Studies have found that people with Type A or Type AB are at higher risk for gastric cancer. Additionally, if you have Type A, Type B or Type AB blood, you may have a higher risk for pancreatic cancer.
Ichor originates in Greek mythology, where it is the "ethereal fluid" that is the blood of the Greek gods, sometimes said to retain the qualities of the immortals' food and drink, ambrosia and nectar. Ichor is described as toxic to humans, killing them instantly if they came in contact with it.

O negative blood is often called the 'universal blood type' because people of any blood type can receive it. This makes it vitally important in an emergency or when a patient's blood type is unknown.
Being pregnant, Naide from Turkiye discovered that she had the Rh-null blood type - the rarest in the world, also known as "golden blood". Less than 50 people have it. As she faced complications, she needed an urgent blood transfusion.
The O gene is recessive, so a person must inherit an O gene from each parent to have type O blood. The Rh negative gene is also recessive, so a person must inherit an Rh negative gene from each parent to be Rh negative.
Rh-negative blood is rare because it's a recessive genetic trait, meaning you need two copies of the non-functional gene (one from each parent) to be Rh-negative, while Rh-positive (having the D antigen) is dominant. This recessive nature means it's less common overall, appearing most frequently in specific populations like Western Europeans, possibly due to historical genetic bottlenecks or selective pressures, though the exact evolutionary reasons are still debated.
In Ancient Greece, it was thought the gods had golden blood. Called Ichor, this ethereal fluid was fabled to have immortal properties, but was toxic to mere mortals.

Although there is no proven correlation between blood type and personality, many matchmaking services use it.
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.
The O Negative Effect program is back for 2026: Whole blood O negative donors will receive a $50 e-gift card for each whole blood donation and double red O negative donors will receive a $100 e-gift card. *
