Lead Testing and Health
Lead may be invisible, but its impact on health is anything but.
Even low levels of lead can damage the brain, kidneys, and nervous system—especially in children and pregnant women.Regular lead testing at home is the first line of defense against silent exposure.
Why Is Lead Dangerous?
Lead interferes with the body’s ability to produce hemoglobin, slows cognitive development, and raises blood pressure.
According to the CDC, no safe blood lead level exists; action is recommended if children reach 3.5 µg/dL or higher.
Symptoms often appear only after prolonged exposure, making proactive testing essential。
Common Sources of Lead in Your Home
Aging Lead‑Based Paint (homes built before 1978).
Tap Water from Lead Pipes, Solder, or Brass Fixtures.
Contaminated Soil near Roadways or Industrial Sites.
Imported Toys, Ceramics, and Cosmetics with Lead Pigments.
Knowing where lead hides helps you target the right tests.
