Blood type

Can you change your blood type?

Many people wonder if it’s possible to change their blood type. This topic raises many questions, and it’s important to distinguish facts from myths. In this blog, we dive into the science behind blood types and explore whether a change is possible.

What are blood types?

Blood types are determined by the presence or absence of certain antigens on the surface of red blood cells. The most common classification is the ABO system, which includes four main types: A, B, AB, and O. Additionally, the Rh factor (positive or negative) plays a role in determining your blood type.

Can you change your blood type?

An individual’s blood type is genetically determined and normally does not change during their lifetime. The antigens on red blood cells are set by the genes inherited from your parents. This means your blood type is a fixed part of your genetic code and cannot be altered by diet, medication, or other external factors.

Exceptions and medical procedures

However, there are some rare circumstances where a blood type change can occur:

  • Bone marrow transplant: When a person undergoes a bone marrow transplant from a donor with a different blood type, the recipient’s blood type can change to that of the donor. This happens because the new bone marrow produces new blood cells with the donor’s blood type.
  • Rare diseases: In extremely rare cases, certain diseases or medical treatments can affect the blood type. However, these are exceptions and occur very rarely.
