  I think that the definition for serum would be blood plasma which get seperated from its fibrinogen..

  Isabell, here I give you a clue.
  If we want to obtain plasma, we need to add ANTICOAGULANT mixed with our blood sample. Whereas, if we want to obtain serum, we do not need that substance. After being incubated for few minutes, we centrifuge our blood sample and we get our plasma or serum.
  So? Now it’s time for you to get the correct answer 🙂
