Hi Alicia, You can find your center's hours of operation by visiting http://www.grifolsplasma.com/en/web/plasma/locations/find-a-donation-center and clicking on your plasma center location.
The new donor appointments are first come first served...they fill up fast the latest you want to get there is 11AM
As a new patient on Sunday you want to go as early as you can cuz they close at 4 PM. They have a set amount of slots for new patients.
I don't know, however they close at 4pm.
Thanks! Your answer is awaiting moderation.
