According to the American Red Cross, only about 7% of the United States population has type O-negative blood. This statistic often raises the question: `How rare is O-negative blood?` While not the absolute rarest, its low prevalence combined with its life-saving compatibility makes it one of the most consistently sought-after blood types for hospitals and emergency services.

Fewer than 50 people worldwide are known to have golden blood, a precious and exceptionally rare blood type medically known as Rh null. This unique blood lacks all Rh antigens, posing significant health challenges and severe transfusion difficulties for those who possess it.

Worldwide, a blood type known as Rh-null is one of the most difficult to source, with fewer than 50 known cases ever reported globally [4]. It is often referred to as “golden blood” because of its extraordinary rarity, directly addressing the query about what is the hardest blood type to get donor [4].

With more than 40% of Americans having O+ blood, its commonness is a stark contrast to the world's rarest types. For those with exceptionally rare blood, knowing **what is the hardest blood to donate?** is a matter of life-or-death, impacting the speed and reliability of crucial transfusions.

The majority of the global population, around 85%, has Rh positive blood. Despite common misconceptions, Rh positive is not rare; it is significantly more common than Rh negative blood.

While human blood is consistently red due to the iron-rich protein hemoglobin, its exact shade can differ slightly depending on oxygen levels. But what is a rare blood color in nature? The answer expands far beyond human physiology, encompassing remarkable biological adaptations in the animal kingdom.

With less than 50 known individuals throughout history, the rarest blood type is a medical marvel. But who has the rarest blood in the world, and what are the profound implications for those who carry this unique genetic trait? The story of 'golden blood' is one of immense medical value and significant personal risk.

While O-negative blood is always in high demand, it accounts for about 7-9% of the population, making it far from the rarest blood type. The frequent need for O-negative blood in emergencies often creates a misconception about its true rarity.

With less than 50 known cases worldwide, the title for the rarest blood type belongs not to a common ABO type, but to the extraordinary Rh-null, also known as “golden blood.” Understanding which blood group is rare involves moving beyond the common A, B, AB, and O types.

The human blood system is incredibly complex, with hundreds of possible antigen variations beyond the common ABO and Rh systems. With fewer than 50 known cases worldwide, the rarest blood type, Rhnull, presents unique and profound challenges for individuals requiring a transplant or transfusion, a condition sometimes called 'golden blood'.
