Since plasma is composed of approximately 92% water, the body replaces the plasma taken from your donation very quickly, usually between 24-48 hours. A donor can safely donate twice in a seven-day period, but not two days in a row. We encourage all of our donors to drink plenty of fluids if they plan to donate twice a week on a regular basis. While a donor may be eligible to donate up to twice per week, B Positive reserves the right to not allow an individual to donate twice in one week for any reason at any time.
