What is the primary goal of blood screening for infectious diseases?

The primary goal of blood screening for infectious diseases is to prevent the transmission of pathogens through transfusion. This is crucial because blood transfusions can transmit various infectious agents, including viruses, bacteria, and parasites, which can pose significant risks to patients receiving transfusions. By rigorously testing donated blood for these infectious diseases, blood banks can ensure that only safe and healthy blood products are used for transfusions.

This preventive measure protects not only the immediate recipient by reducing the risk of transfusion-related infections but also contributes to overall public health safety. It is essential to minimize the risk of transfusion-transmitted infections through comprehensive screening protocols that check for a broad spectrum of infectious agents.

While assessing donor health and fitness, enhancing the nutritional quality of blood, and increasing the shelf life of blood products are important considerations in blood banking, they do not primarily address the critical concern of infectious disease transmission, which is a central focus of blood screening efforts.
