This highlights the importance of innovations in blood screening and testing, which enhance the reliability of transfusions and protect patient health.
What are the risks associated with blood transfusions?
The risks associated with blood transfusions include allergic reactions, fever, hemolytic reactions, and transmission of infections. Allergic reactions can occur in about 1-3% of transfusions, leading to symptoms like hives or itching. Febrile non-hemolytic transfusion reactions, caused by the recipient’s immune response to donor white blood cells, can happen in approximately 1% of cases. Hemolytic reactions, which occur when the recipient’s immune system attacks the transfused red blood cells, can be acute or delayed and are serious complications. Additionally, although rare, there is a risk of transmitting infections such as HIV, hepatitis B, and hepatitis C, despite rigorous screening processes. According to the American Red Cross, the risk of contracting a serious infection from a transfusion is about 1 in 1.5 million units transfused, highlighting the importance of ongoing innovations in blood screening and testing to enhance transfusion safety.
How can innovations mitigate these risks?
Innovations in blood screening and testing can mitigate risks associated with transfusion safety by enhancing the detection of infectious agents and improving blood compatibility.
