Is RH Negative B Blood Type Rare?

RH Negative Type B Blood is a very rare blood type, unlike the common A, B, O, AB, etc. RH negative type B blood is extremely precious and rare, with limited inventory in blood banks. There are considerable risks when RH negative type B blood requires a large amount of blood transfusion, as this blood type is not as easy to find as common blood types. Therefore, RH negative type B blood is a relatively special blood type.

1. RH Negative Type B Blood as "Panda Blood"

RH negative type B blood is very rare and precious. If a person with RH negative type B blood receives a transfusion of other blood types, it can lead to immune hemolytic reactions, endangering their life. Although the A, B, O, and AB blood types are more common, RH negative type B blood is very rare, accounting for less than 1% of people with Rh blood types. In summary, RH negative type B blood is rare, and if a large amount of blood transfusion is required due to an accident, it can be troublesome as blood banks may have insufficient inventory.

2. Introduction to Rh Blood Type

Most people have Rh-positive blood, while a small minority have Rh-negative blood. Rh-positive blood accounts for approximately 99%, while Rh-negative blood accounts for only about 1%. The Rh blood type system is the most complex among red blood cell blood types, with the D antigen being the most potent. Therefore, red blood cells containing the D antigen are referred to as Rh-positive, while those lacking the D antigen are referred to as Rh-negative.

3. The Specificity of RH Blood Type

The RH blood type is both special and rare, requiring proper registration in blood banks for emergency use. In China, people with RH-negative blood are very rare, and they can only receive RH-negative blood. Therefore, A-type RH-negative blood refers to a person with ABO blood type A and RH blood type negative.
