can a muslim donate plasam?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah and that Muhammad  is His slave and Messenger.

As it is permissible to donate blood, it is also permissible to donate blood plasma because it is part of it and is one of its components. For more benefit, please refer to Fatwa 85317.

Allah Knows best.
