Can A Blood Transfusion Change Your Dna
Olivia Luz
Studies have shown that donor dna in blood transfusion recipients persists for a number of days sometimes longer but its presence is unlikely to alter genetic tests significantly.
No it does not change your dna. Scientific american explains that when donor blood is mixed into the body with a transfusion that person s dna will be present in your body for some days but its presence is unlikely to alter genetic tests significantly it is likely minimized because the majority of blood is red cells which do not carry dna the white blood cells do. If whole blood is used in an emergency transfusion it causes a fever called febrile non haemolytic transfusion reaction as the recipient s own white cells destroy the foreign dna. Only one systemic process such as bone marrow transfusion could actually change the dna profile of a recipient.
So to answer the question does a blood transfusion change dna. Most of the new blood is composed of red blood cells which do not contain genetic information. Most people only receive red cells or blood plasma during medical procedures and neither one of those blood components contain any dna material. Even blood components that.
Donated blood is spun in a centrifuge to separate it into plasma platelets red cells and white cells and only the first three are used for transfusions. To receive a straight blood transfusion does not change a dna but could mess with the results for a few days then the recipients own blood cells will take over and over whelm those of the donor. Interestingly if you have received a blood transfusion you will carry the dna of the donor in your blood stream for a time depending on how much blood you received. Transfused blood still needs to be a match to the recipient s blood type including the abo blood groupings.

This does not mean that donor dna and donor blood cannot have an effect on the recipient s body. Most people only receive red cells or blood plasma during medical procedures and neither one of those blood components contain any dna. Transfused blood does however host a significant amount of dna containing white blood cells or leukocytes around a billion cells per unit roughly one pint of blood. Getting a standard blood transfusion cannot and will not change your dna.Blood transfusions cannot change your dna in any way. Red blood cells the primary component in transfusions have no nucleus and no dna. Could a blood transfusion change your dna answered by dr.
