Blood products are components derived from human blood that are used for medical treatments. These products include red blood cells, plasma, platelets, and cryoprecipitate. They are essential for patients who have lost blood due to surgery, trauma, or medical conditions like anemia. These products are collected through a process called blood donation and are carefully tested for safety. Once processed, they can be stored and transfused to patients in need, helping to restore blood volume, improve clotting, and support overall health during medical procedures or treatments.
