FDA Donation Rules
The FDA regulates plasma donation frequency for your safety. Here are the official rules:
The Core Rules
- Maximum: 2 donations per 7-day period

- Calendar week: Most centers track Sunday-Saturday
- No exceptions: Centers must follow FDA guidelines
Why These Limits?

Frequency FAQ
Can I donate 3 times per week?
No. FDA regulations strictly limit plasma donation to twice per 7-day period. No center can allow more.
What if I wait exactly 48 hours?
You can donate. 48 hours is the minimum. The center's system will allow you to donate once 48 hours have passed.
Does donating twice weekly hurt my health?
Not for most people. If you're healthy, well-hydrated, and eating properly, twice-weekly donation is safe. Listen to your body.
Can I donate at two different centers?
No. Centers share a national database. You can only donate at one center, and total donations cannot exceed twice weekly across all centers.
What happens if I try to donate too soon?
The system will stop you. When you check in, the computer will show you're not eligible yet and tell you when you can return.
Always follow FDA guidelines and listen to your body. Individual health factors may affect your optimal donation frequency.
