"Many blood brokers use arbitrage to obtain blood cheaply and then sell it all the while using "charitable" drives as the motivating factor."
Hi Questioningmyfaith,
Just a couple of things on blood regarding processing costs: 1. The type has to be identified with a cross-match 2. It has to be tested for HIV, HIV-2, Hepatitis B+C, Syphilis, West Nile virus etc. 3. It has to be put in cold storage until used and only after all of these can sub-components be extracted.
So yes there are profits to be made, but its also not cheap to prepare. Blood donation is just the first step.
