I have been researching information on various blood fractions that are available. In my research I have found that Albumin contains up to 4 % of Plasma and immunoglobulins up to 4%. Suppose I was to receive a serum/injection of either, how much would actually be of blood being a fraction? What alternatives are available for immunoglobulins, for example: to counteract a snake bite? Are these alternatives be available world-wide, like Thailand for example?
Any insight would be helpful.
