Quick Answer

Temporary deferrals have a set waiting period (days to 12 months) after which you can return. Permanent deferrals mean you cannot donate plasma at any center, typically due to positive disease tests or high-risk medical history. Most first-time deferrals are temporary.

Understanding Temporary Deferrals

A temporary deferral means you're currently ineligible but can return after a specific waiting period. These are the most common type of deferral.

Common Mistakes About Deferrals

  1. Assuming all deferrals are permanent: Most first-time deferrals are temporary and resolvable
  2. Not asking about return date: Always ask when you can come back
  3. Giving up after one deferral: Temporary issues like low iron are easily fixed
  4. Not disclosing medical history: Incomplete information can lead to longer deferrals
  5. Trying a different center immediately: Centers share information; be honest about recent deferrals
  6. Assuming you know the reason: Always ask staff to explain the specific cause

What to Do After a Deferral

  1. Ask for specifics: Get the exact reason and duration
  2. Get it in writing: Ask for documentation if possible
  3. Mark your calendar: Set a reminder for your eligible return date
  4. Address the cause: Take steps to resolve temporary issues
  5. Consult your doctor: For medical deferrals, get professional guidance

Frequently Asked Questions

What is a temporary plasma deferral?

A temporary deferral means you cannot donate for a specific period but can return after that time passes. Examples include low iron (days to weeks), tattoos (3-12 months), or certain medications (varies by medication).

What causes a permanent plasma deferral?

Permanent deferrals are typically caused by positive tests for certain diseases (HIV, Hepatitis B/C), history of IV drug use, organ transplants, or certain blood disorders. These are safety-related and cannot be reversed.

How do I know if my deferral is temporary or permanent?

The plasma center staff will tell you the deferral type and duration. Temporary deferrals come with a specific return date. If no return date is given, ask the staff directly about your status.

Can a permanent deferral ever be reversed?

In rare cases, permanent deferrals may be reconsidered if they were based on conditions that have changed (like updated FDA guidelines). However, deferrals for positive disease tests are typically not reversible.

Will a temporary deferral show up at other plasma centers?

Minor temporary deferrals (low iron, elevated pulse) usually stay at that center. However, centers share information through databases, so deferrals for more serious reasons may appear at other locations.

How long after a tattoo can I donate plasma?

In states with regulated tattoo facilities, the deferral is typically 3-4 months. In unregulated states or for tattoos from unlicensed facilities, the deferral is 12 months.
