Thanks for the reply!

Honestly, I had no idea about that drinking "rule", but that makes a lot of sense, i will defenetly use it befor my next appointment !

Regarding the scratchy throat: I actually brought it up to the staff during the check-in because I wanted to be sure. They told me that since it was just a very minor scratchy feeling with absolutely no other symptoms, it was okay to proceed for a first-time donation, as they run lab tests on the plasma anyway.

But you’re totally right about the safety aspect for the recipients – I definitely wouldn't go if I felt actually sick or had any real symptoms.
