AB button (blood type)

An emoji representing blood type AB, designed as a red square button with white letters. It is commonly used when displaying medical information.

AB blood type is one of the rarest blood types worldwide. Particularly in Asia, it holds special significance as only about 10% of the population has this blood type.

Medically, AB type is known as the 'universal recipient' as it can receive blood from all blood types during transfusions. This unique characteristic makes it particularly important in the medical field.

In modern digital culture, this emoji is also used to symbolize diversity and uniqueness. It is sometimes used in games and animations to represent rare characters or items, and can also be used to indicate distinctive or complex characteristics.
