Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Lead
As part of comprehensive health screening, a lead blood test helps you understand your environmental exposure to this toxic metal. Identifying lead levels early is key to protecting your long-term well-being.
What It Measures
This test measures the concentration of lead in your blood. Lead exposure can occur through deteriorating lead-based paint, contaminated drinking water from old pipes, contaminated soil, and occupational settings such as construction, battery manufacturing, and recycling.
Why It Matters
There is no known safe level of lead exposure. Even low levels of lead in the blood can be associated with cognitive difficulties, kidney problems, and cardiovascular effects. Children are particularly vulnerable, as lead exposure may affect neurological development.
When to Test
Testing may be recommended if you live in a home built before 1978, work in industries involving lead, have hobbies such as stained glass or pottery, or experience unexplained symptoms. Consult a healthcare professional for interpretation of results.
Symptoms
Low Levels
Low levels of lead are generally not a cause for concern and may indicate minimal exposure.
High Levels
Fatigue, cognitive difficulties, abdominal pain, joint and muscle pain, kidney issues, headaches.
Lifestyle Tips
If you live in an older home, test paint and water for lead. Run cold water for at least 30 seconds before drinking if you have older pipes. Maintain good hygiene practices such as regular handwashing, especially before meals. Eat foods rich in iron, calcium, and vitamin C, which may help reduce lead absorption.
Frequently Asked Questions
What are the most common sources of lead exposure today?
Today, the most common sources include deteriorating lead-based paint in older homes, contaminated water from aging lead pipes, contaminated soil near industrial areas, and certain occupational and hobby-related exposures.
Is there a safe level of lead in the blood?
Health authorities generally agree that there is no known safe level of lead in the blood. Even low levels of exposure can be associated with health effects, particularly in children. Regular monitoring can help identify exposure early.
How long does lead stay in the body?
Lead in the blood has a half-life of about 30 days, but lead stored in bones can remain for decades. This means past exposure can continue to affect the body long after the source is removed.
