Psoriasis is a chronic disease that causes the rapid build-up of cells on the skin surface forming thick scales. Patients will often be affected by itchy dry red patches that can be painful as well.

Leukopaks are obtained by a donation process where blood is withdrawn from the donor via leukapheresis utilizing an aphresis machine such as the Spectra Optia. The donor’s white blood cells are selectively collected and the remaining blood is reinfused to the body.

PPA's fresh Psoriasis leukopaks are obtained by aphresis from donors with Psoriasis. All of our donors are fully consented and IRB approved.
