Question

Is O negative blood group rare?

Answer 1

The presence and absence of antibodies and hereditary antigenic compounds on the surface of red blood cells are used to classify blood types. Depending on the blood group system, these antigens can be proteins, carbohydrates, glycoproteins, or glycolipids.

Complete answer:
Because anyone can get red blood cells from negative donors, they are commonly referred to as "universal donors". People with O negative blood can only receive red cell donations from O negative donors.
Although O negative blood accounts for roughly 8% of the population, it accounts for around 13% of hospital requests for red blood cells.
Antigens, which are proteins and carbohydrates that reside on red blood cells and determine the type of blood, are also present in your blood. Only two blood type systems are frequently utilised, despite the fact that there are at least 33.
The ABO and Rh-positive/Rh-negative blood type systems are these. These two categories combine to generate the eight basic blood types that the majority of people are familiar with: A-positive. A-negative, B-positive, B-negative, AB-positive, AB-negative, O-positive, O-negative, AB-positive, AB-negative, O-positive, O-negative.
When it comes to blood type, you can get the AB blood type by inheriting an A gene from one parent and a B gene from the other. You may also inherit B antigens from both parents, giving you the blood type BB, or B.

Note:-
For emergencies, air ambulances and emergency response vehicles carry O negative supplies. Obtaining enough O negative blood is an ongoing issue, and your donations are constantly needed. Because it can be given to people of any blood type, O negative blood is often referred to as the "universal blood type". This makes it critical in an emergency or when the blood type of a patient is unknown.
