How much Venom required for 1 of antivenom?

The amount of venom required to produce one unit of antivenom can vary significantly depending on the type of snake and the specific production process. Generally, it takes several milligrams to grams of venom from the snake species in question to immunize animals (like horses) for antivenom production.
