Answer Details
The best word to complete the sentence is "before." Blood is usually screened before transfusion. This means that medical professionals check the donated blood for any infections, diseases, or other potential problems before giving it to a patient. Screening helps ensure that the transfusion is safe and effective for the recipient.
For example, if the blood contains a virus or bacteria, it could make the patient sick or even put their life in danger. Screening is a crucial step in the transfusion process that helps prevent these types of complications.
