The only blood type that has a mysterious code

In the world, there are only four main blood groups - I, II, III, and IV. But among them, a rare group that attracts special attention from scientists and medical professionals has a unique and mysterious code - the Rh factor "Rh-null," or the so-called "golden blood".

This rarest blood group belongs to the Rhnull type - meaning it doesn't contain any of the 61 possible antigens of the Rhesus system. According to statistics, throughout the history of medicine, fewer than 50 people with such blood have been recorded worldwide. This is what makes it truly unique.

The main feature of "golden blood" is that it can be transfused to almost any person with a negative Rh factor. It is universal for Rh-negative patients, but itself is extremely scarce. In case of an emergency situation for an Rhnull carrier, finding a donor is practically impossible, since compatibility can only be with a person with the same rare phenotype.

Scientists still cannot fully explain the nature of Rhnull. It is believed to be a genetic mutation, found mainly in descendants of consanguineous marriages or in isolated populations. Some researchers call this blood "the blood of gods" due to its unique properties and rarity.

Currently, work is being done worldwide to track Rhnull carriers and create a special database so that, if necessary, they could save the lives of others. Nevertheless, the mystery of the origin of this blood remains not fully revealed - and continues to intrigue both scientists and ordinary people.
