Infection and/or inflammation will both bump ferritin briefly higher. The body knows iron can feed infection (all pathogens need access to iron to reproduce) and fan inflammation (iron the ultimate pro-oxidant), so empty "apo-ferritin" is pumped out in a desperate attempt to sequester any free iron whenever the body experiences infection or inflammation. The ferritin blood test reads empty apo-ferritin the same as iron loaded ferritin, so this can result in a jump, or even false positive into out-of-range high levels. This typically will also cause a dip in saturation and serum iron.
I wouldn't sweat an isolated blip in iron labs that occurs during or shortly after a known infection. As long as saturation holds in the middle third of its normal range you should not have an issue with excess iron tissue damage.
This said, I like to keep my ferritin out of triple digits, so if you've donated before and don't mind doing so again a trip to the blood bank couldn't hurt. Each donation should drop ferritin by around 30-50 points from your previous average, so a single donation would likely take you out of triple digits and back to optimal iron homeostasis.
