Transient decrease of blood clotting function: after donating plasma, the concentration of blood clotting factors in the body will decrease due to the decrease of blood clotting function of plasma donors, triggering the symptom of transient decrease of blood clotting function. 2. Decrease in immunoglobulin: plasma is rich in immunoglobulin, and plasma donation leads to a decrease in the concentration of immunoglobulin in the body and a decrease in the immune function, which can easily induce colds and fever, etc. However, timely supplementation after plasma donation can lead to recovery. 3. Dizziness: After donating plasma, the blood volume may drop briefly, resulting in dizziness. Plasma donations must be made through regular hospitals or blood donation vehicles, and need to comply with the provisions of the plasma donation, to avoid irregular channels, causing cross-infection.
