Short Answer
Whole blood donation collects all blood components together, while plasma donation collects only plasma and safely returns the remaining blood components to the donor.
Detailed Explanation
In whole blood donation, approximately 350–450 ml of whole blood is collected in one donation.
During plasma donation, an apheresis machine separates the plasma and returns red blood cells, white blood cells, and most platelets back to the donor.
Because red blood cells are returned, plasma donors generally recover faster and may be eligible to donate plasma more frequently than whole blood, subject to national guidelines and medical eligibility.
