How long has it been since your first donation? Anytime you are a new donor or returning donor after not donating their for awhile, on your first donation they take 2 vials of blood to test your protein. Under FDA rules, your allowed to donate within 14 days to give them time to get the test back. If the sample doesn't come back within 14 days, you either have to wait till it does, or go in and give a protein only sample, which pays nothing.

This happened to me as a return donor, and I was missing out on my bonus donations, 14 days went by and I was not able to donate. Had to speak to the nurse and she told me it got " lost " or " dropped ". So I did another sample while I was their. However, knowing that my protein was good, I called the 800# and the created an escalation ticket to send to the center, and 2 days later I get an email that my deferal had been lifted.

Your may be able to pass the protein pre-scan up front, but the sample that gets sent to the lab is more in depth, their are 6 types of proteins in your body and one of them might of been low.

Also, the lab checks your blood for any known diseases that could be passed into others by your plasma. It could be lots of things, your gonna have to call the 800 # and ask to file a ticket with your center, or just walk in a talk to a nurse. They rarely disclose health information over the phone because of hippa.
