When people go in to donate blood, first they are asked a series of questions about their lifestyle. The blood is tested, and then they're asked if they think their blood is suitable for patient care. There are many ways in which they try to screen blood. If they answer questions, and if blood testes positive, it is destroyed. People are informed of the results and receive counseling from the blood center because they have a health care issue that needs to be attended to.
Testing is a very sophisticated technology which is very demanding.
If you look at the testing systems we have in the U.S. today, we're doing multiple tests for each of the major viruses, not including bacteria other than syphilis, or other bacteria. Our process is a single process, and it's been developed to work inside the plastic containers that blood is collected in, and it uses less instrumentation than is required for the sophisticated tests in place in the U.S. today. We think our technology will be more accessible to them in terms of implementation. So, instead of testing blood, you would be treating it. I think there are clearly some parts of the world where treating without testing may make the most sense.
