Blood Test: Lead
A lead test is used to determine or measures the amount of lead in the blood. This test is used to screen people at risk for lead poisoning, including industrial workers and children who live in urban areas. It is also used to see if treatment for lead poisoning is working.
In adults, a low level of lead exposure isn't considered dangerous. However, in babies and young kids whose brains are still developing, even a small amount of lead can cause learning disabilities and behavioral problems. At higher levels, lead exposure can cause seizures, coma, and even death. Usually, the procedure is done inside of the elbow or back of the hand then a tube inserted to draw the blood out. In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding. When the needle is inserted to draw blood, you may feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.
