What is a strategy that should be used to test for lead poisoning?

The gold standard for testing for lead poisoning is a blood test. This test measures the amount of lead in a person's blood, which can indicate recent or past exposure to lead. Blood lead levels can be used to diagnose lead poisoning and to monitor the effectiveness of treatment.

Other tests that can be used to test for lead poisoning include:

* Hair analysis: This test measures the amount of lead in a person's hair, which can indicate long-term exposure to lead.

* Urine analysis: This test measures the amount of lead in a person's urine, which can indicate recent exposure to lead.

* Bone lead analysis: This test measures the amount of lead in a person's bones, which can indicate long-term exposure to lead.

The specific test or combination of tests that is used to test for lead poisoning will depend on the individual's age, health history, and potential for exposure to lead.
