The results of endotoxin are connected to the amount of endotoxin from the merchandise dose administered to the affected individual. Because the dose differs from products to merchandise, the endotoxin limit is expressed as K/M. K is five.0 EU/kilogram (kg.), which represents the approximate threshold pyrogen dose for human beings and rabbits. That is the stage at which a product is adjudged pyrogenic or non-pyrogenic.
