Frequently Asked Questions
I just have allergies, not a cold - can I donate?
Seasonal allergies (not illness) usually don't disqualify you. If you have sneezing and runny nose from allergies but no fever or feeling unwell, you can typically donate.
What if I feel a cold coming on?
If you're in the early stages of getting sick, it's better to wait. Donating when you're about to get sick can make your illness worse and your plasma may be affected.
Will they test me for illness?
Centers check your temperature and ask about symptoms. They don't test for colds, but a fever will show on temperature check.
Don't try to hide symptoms. Donating while sick is bad for you and can affect plasma quality.
