Physicians Plasma Alliance (PPA) has been a great paid plasma donation center (for disease diagnosed people) to work with. I have not personally donated there, however I referred three of my close friends to Physicians Plasma Alliance after two of them got Lyme Disease, and one got Malaria while visiting Africa. None of them had any complaints about Physicians Plasma Alliance or the process, and they all told me that Kevin King, PPA's owner, went to great lengths to take care of them, set them up in a comfortable hotel (they flew to TN from MA to participate), and paid them generously ($400+ per plasma donation) with all expenses paid and a flexible schedule. I wish more people knew about Physicians Plasma Alliance since research has so much to gain, as do the patients with these diseases.
