Quick Answer
Plasma donation deferrals fall into two categories: temporary (can donate after a waiting period) and permanent (cannot donate). Common temporary deferrals include recent tattoos (3-12 months), antibiotics (2 weeks-6 months), travel to malaria zones (3-12 months), and low protein (retest immediately). Permanent deferrals include HIV, Hepatitis B/C, certain cancers, and IV drug use.

Cancer (Varies by Type)
| Cancer Type | Deferral |
|---|---|
| Blood Cancers (leukemia, lymphoma, myeloma) | Permanent |
| Solid Tumors (breast, colon, etc.) | 5 years cancer-free, then eligible (varies by center) |
| Skin Cancer (basal/squamous cell) | No deferral if removed; melanoma = 5-year wait |

Frequently Asked Questions
Can I donate if I have a tattoo from 6 months ago?
Depends on your state and whether the tattoo was done at a licensed shop. In regulated states (most of the U.S.), licensed tattoos have no deferral. In non-regulated states or for unlicensed tattoos, you must wait 12 months. Check with your plasma center—they'll know your state's rules.
If I'm deferred, will I be told why?
Yes. Plasma centers must inform you of the deferral reason and duration. For temporary deferrals, they'll tell you when you can return. For permanent deferrals (e.g., positive viral test), you'll receive a confidential notification and may be advised to follow up with your doctor.
Can I donate if I take antidepressants?
Yes. Antidepressants (SSRIs, SNRIs, tricyclics, etc.) do not disqualify you from donating plasma. As long as your condition is stable and you're not experiencing severe side effects, you're eligible.
How do plasma centers know if I'm deferred at another center?
Plasma centers use a national donor database that tracks deferrals across all centers. If you're deferred at one center, all centers will see it. Attempting to donate while deferred can result in permanent deferral from the entire network.
