I will chime in. My daughter is one of those that benefit from people donating plasma. She was diagnosed with an Immune Deficiency when she was 4 years old...her body lacks the ability to fight infections and make memory to different viruses and bacteria (when we tested her she was up to date on all her shots and when they checked her bloodwork, her body didn't make any titers to her vaccines). Every month she receives IVIG (Intervenious Immunogloubins) which is made from donated plasma. It takes over 1,000 donations just to make 1 infusion...this infusion allows my daughter to live a normal life! I guess we do technically have to pay for it since its a "medication", but our insurance covers it. One infusion with supplies involved costs up around $4,000.00. Thankfully, we have awesome insurance and only pay 1,000.00 out of pocked before she's covered 100%.
I say please donate...not just to make a few bucks...but to help kids and adults just like my daughter (IVIG is also used for many other diseases). There have been times where there is a shortage and some people cannot get there immunogloubins.
