Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body. Lead is a highly toxic metal and a very strong poison. It is found in lead-based paints, including paint on the walls of old houses and toys.
A lead test is used to determine the amount of lead in the blood. Lead is a heavy metal found naturally in the environment as well as in many common consumer products. Though it serves no purpose in the human body, most people have a small amount of it in their bodies because it's so prevalent in our surroundings.
