I think he was referring to test itself. I assume during the test that solutions are used. But, this is the number he said.

When they get blood from me they access my Port in my chest which requires a kit that is discarded . Where as if they poked my arm it would be just a needle.

David, on another matter, I was recently relinquished blood for a Hepatitis and HIV test. They took four vials of blood. To your knowledge, why so many?
