Multiple Sclerosis (MS) is a chronic disease that is often progressive. The disease is characterized by damage to the central nervous system. This includes the brain, spinal cord and the optic nerve. MS can cause numbness, severe fatigue, blurred vision and impaired speech and impaired muscular coordination.

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.
