A blood sample is needed. For information on how this is done.

Preparation for analysis

If your child is going to have this test, it can help to explain what he or she will feel during the procedure and even demonstrate with a doll . Explain why the test is being done, as knowing “the how and why” can reduce your anxiety level.

Symptoms during analysis

When the [[needle is inserted to draw blood, you may feel moderate pain or experience a prick or stinging sensation. Afterwards, there may be some throbbing sensation.

Causes

This test is used to screen for people at risk for lead poisoning, such as industrial workers and children living in urban areas. It is also used to see if treatment for lead poisoning is working.

Although lead has no function in the body, it is generally found in the body in some quantity, as it is very common in the environment. Low lead levels in adults are not believed to be harmful, but in infants and children they can lead to toxicity that can lead to impaired intellectual or cognitive development.

Lead poisoning

Normal blood lead test values

  • Adults: Less than 20 micrograms / dL of lead in blood
  • Children: Less than 10 micrograms / dL of lead in the blood
  • Note: dL = deciliter

The ranges of normal values ​​may vary slightly between different laboratories. Talk to your doctor about the meaning of your specific test results. Meaning of abnormal blood lead test values

Adults exposed to lead should have lead levels in their blood below 40 micrograms / dL. Treatment is recommended if you have symptoms of lead poisoning or if your blood level is greater than 60 micrograms / dL.

In children, a blood lead level greater than 10 micrograms / dL requires additional testing and monitoring. The source of the lead must be identified and eliminated. A lead level greater than 45 micrograms / dL in a child’s blood generally indicates the need for treatment. However, treatment can be considered as low as 20 micrograms / dL.

Risks

Veins and arteries vary in size from patient to patient and from one side of the body to the other, which is why obtaining a blood sample from some people can be more difficult than from others.

Other risks

  • Excessive bleeding
  • Fainting or feeling dizzy
  • Hematoma (collection of blood under the skin)
  • Infection (a slight risk whenever the skin is broken)
