If you were denied for a medical reason, discuss with your doctor and if he gives the OK call the blood center (7314274431) and see if they can accept a doctor's note. Otherwise 2 weeks for platelets or plasma and 16 for whole blood.
Depending on what you donated. If platelets or plasma, only about week or so and if whole blood, about 16 weeks or so
