Plasma transfusion involves which practice?

Plasma transfusion involves which practice?

• A. Giving young blood or plasma to older people; early studies show weak or inconsistent benefits
• B. Transferring red blood cells to boost stamina in athletes
• C. Transferring plasma to donors for storage
• D. Using plasma to treat bacterial infections

Answer: (A)

Plasma transfusion means giving plasma from one person to another to provide plasma components like proteins and clotting factors. The option described involves infusing plasma from young donors into older people as a potential anti-aging or rejuvenation approach. Early studies suggested possible benefits, but those effects were weak or inconsistent, and the overall evidence hasn’t supported a reliable positive outcome. So this described practice is the best match for what plasma transfusion has been explored as, even though it isn’t a proven, standard therapy. The other options reference different concepts—transfusing red blood cells, collecting plasma for storage, or using plasma to treat bacterial infections—which are not what plasma transfusion, in the strict sense, denotes.
