Don't know your blood type?
Your attending doctor or a rapid test from the pharmacy will provide the answer.
Only 43 people worldwide have “golden blood”.
The blood group also became an issue in the context of the corona pandemic. In 2020, Austrian researchers informed that the blood type should determine whether you are infected with Covid-19. Eva Maria Matzhold and Thomas Wagner from the University Clinic for Blood Group Serology and Transfusion Medicine at the Medical University of Graz concluded from their study results:
People with blood group zero are less likely to get the Sars-CoV-2 coronavirus
than people with blood groups A, B or AB.
Corona patients with blood group A also have more frequent respiratory problems than those with blood group AB or B, according to the Siemens company health insurance company SBK.
According to the health insurance company, this is probably not due to the blood group itself
, but to certain characteristics that have an influence on the immune function and are inherited together with the blood group.

However, the fact is: certain blood groups are more common than others, which is particularly relevant in the area of blood donation.
In Germany, most people have blood group A (43 percent) and blood group 0 (41 percent)
.
As the German Red Cross (DRK) further informs, there is a high need for blood group 0 for the care of emergency patients, since blood products of this group can be used universally.

Universally applicable: rarest blood group in the world RhNull
There are several blood type systems, the most important of which are the AB0 and Rhesus systems. The Rh system distinguishes between positive rhesus (Rh +) and negative rhesus (Rh-). The AB0 system divides the four blood groups A, B, AB and 0, according to the blood donation service of the Bavarian Red Cross. "
When blood components are transfused, the compatibility of donor blood and recipient blood must be given on the basis of these characteristics,
" says the DRK blood donation service.
If the blood lacks all 55 antigens from the Rh system, it is officially referred to as RhNull.
This is considered to be the rarest blood group in the world because currently only 43 people worldwide are known to have this blood group.
Hence the term "golden blood", which is based on the rare resource gold
.
In theory, these people would be the perfect donors, provided the AB0 group is correct, reports the SBK.
Because the blood group RhNull, unlike other groups, has no rhesus antigens, there are no life-threatening defense reactions with recipient blood, informs the knowledge portal geo.
