- Oral medications only: Metformin and similar usually OK
- No complications: No neuropathy, retinopathy, etc.
Type 2 With Insulin
This is where policies vary significantly:
- Some centers allow: If insulin therapy is stable
- Some centers defer: Any insulin use = deferral
- Ask first: Call your center before visiting
Type 2 Requirements at Most Centers
- Stable for 3+ months: No recent changes in treatment
- A1C under 10: Some centers have A1C requirements
- No hypoglycemic episodes: Recent lows may defer you

Most plasma centers defer Type 1 diabetics because:
- Insulin dependency: All Type 1 requires insulin
- Hypoglycemia risk: Donation can affect blood sugar
- Autoimmune nature: Concerns about plasma quality
- Safety concerns: Risk during donation process
Exceptions
- Very rare: Some centers may evaluate case-by-case
- Research centers: May accept for specific programs
- Blood banks vs plasma: Different from whole blood donation
Insulin and Eligibility
Why Insulin Matters
Plasma centers have strict insulin policies because:
- Human-derived insulin: Historically a concern (now synthetic)
- Hypoglycemia risk: Donation can cause blood sugar drops
- Medical complexity: More variables to manage
Insulin Policy by Center
| Center | Insulin Policy |
|---|---|
| BioLife | Case-by-case; call first |
| CSL Plasma | Varies by location |
| Octapharma | Generally defers insulin users |
| Grifols | Typically defers insulin users |
Policies change - always call before visiting.

Frequently Asked Questions
Can I donate if I take Metformin?
Usually yes. Metformin is an oral medication, not insulin. Most centers accept donors on Metformin.
Will donating plasma affect my blood sugar?
It can. The process may cause temporary changes. Monitor closely and bring snacks.
What if my diabetes is pre-diabetes?
Usually fine. Pre-diabetes typically doesn't affect eligibility as long as it's monitored.
Should I tell them I have diabetes?
Yes, always. Honesty is required on the health questionnaire. Lying can have legal consequences.
This is general information only. Policies vary by center. Always consult your healthcare provider and call the center before visiting.
