After several weeks and many injections, enough antibodies are present in Pamela's blood to begin the sequence of donations. Bloom draws a cup of blood in a process that is similar to a human blood donation, then races with the sample to her lab. In the laboratory, the collected blood is allowed to clot. Allowing the blood to clot makes it easier to separate the solid red and white blood cells from the serum, or liquid part of blood. The serum contains the antibodies to bark scorpion venom.
Bloom uses a centrifuge to spin the blood sample at very high speed.
During the centrifuge process, Pamela's blood separates into its solid and liquid parts. The pure goat serum is then filtered, sterilized, bottled, and frozen. Bloom repeats this process once a week for several weeks each winter. Pamela and three other special ASU goats are the lifesaving donors. Once enough serum has been made to meet the pending seasonal demand, Bloom sends it to a medical laboratory for packaging.
