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.

PPA can obtain whole blood and plasma samples from these patients when they become available to our network of clinicians. Some disease types may have a long backorder depending on the frequency of the disease occurrence in the general population. All samples come from fully consented IRB approved collections.
