Golden blood Rh-null: 43 people on the planet that doctors are hunting for

      Their addresses are kept in secret databases, they receive calls in the middle of the night from other countries, and their own lives hang by a thread. Meet the holders of the rarest blood in the world — Rh-null.

      Imagine: your blood is a universal key to saving dozens of people, but at the same time, it makes you a hostage of your own body. This is how about 43 people on Earth live, diagnosed with Rh-null — blood without a single rhesus antigen. It lacks all 61 known rhesus system antigens. This is absolute purity, a gift from nature to only a select few. The story began in 1961 in Australia when something incredible was discovered in a local Aboriginal woman. Lab technicians thought the equipment had malfunctioned — the results contradicted all laws of hematology. Ten rechecks confirmed the shocking fact: there is not a single rhesus marker in her blood. The world encountered a phenomenon for the first time, which would later be called "golden."

      So why are there so few such people? For an Rh-null individual to be born, a match of the rarest mutations in the genes of both parents is required. The probability is vanishingly small. Today, fewer than fifty carriers are known worldwide, but scientists suspect there may be a few more — many have simply never undergone testing at such a deep level.

      For medicine, these people are an invaluable resource. Their blood is suitable for transfusions to patients with the most exotic rhesus types, for whom regular donor blood is deadly. International hematology centers keep the contacts of carriers in strict secrecy. Every call from another country is someone’s last chance.

      However, the medal has a reverse side. If the Rh-null holder themselves gets into an accident or urgently needs a transfusion, finding a donor for them is almost impossible. The nearest compatible person could be thousands of kilometers away. That’s why many of them donate their own blood in advance and store it frozen in special banks.

      One Swiss doctor spoke about a patient who received six calls in a year asking her to save strangers. She felt not unique, but a hostage of her own biology. Constant fear, responsibility, and the realization that her life is a fragile balance between a gift and a curse. A teacher from Japan, a farmer from Brazil, a programmer from Russia — random people with an extraordinary fate. Their blood is gold, which can become the cause of their demise.
