This test measures the amount of lead in your child's blood. It's usually done on blood taken from a small poke in the heel or a finger, or from a vein in the arm.
A high level of lead in the blood is called lead poisoning. It's most harmful to children younger than age 6 (especially those younger than age 3). It can cause learning disabilities, behavioural problems, damage to the brain and kidneys, and anemia.
Testing for lead is done to:
An older child will have a blood sample taken from a needle poke to a finger or from a vein. If your child is a baby, the sample may be collected from a poke to his or her heel. This is called a heel stick.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. Ask your doctor when you can expect to have your child's test results.
