This test measures the amount of lead in your blood, providing valuable insight into potential lead exposure. By understanding lead levels, you and your healthcare provider can assess your risk for lead-related health issues.
Lead is a heavy metal that can build up in the body over time, causing serious health issues, even at low levels. Lead mainly affects the nervous system, but it can also harm the kidneys, blood, heart, and reproductive organs in adults. Knowing your blood lead level can help guide decisions about reducing environmental exposure. Although lead use has decreased in recent decades, it is still found in some homes and products.
Preparation: No special preparation is needed.
The lead test measures the concentration of lead in your blood. Elevated lead levels can cause various health issues, including cognitive problems, anemia, kidney damage, and reproductive issues. Early detection is crucial for preventing long-term health effects.
Living in older homes (built before 1978) or areas with potential lead contamination can increase your risk of lead exposure. A lead blood test can help assess your environmental risk, providing peace of mind or alerting you to potential hazards in your surroundings.
Even small amounts can lead to potential health problems over time, such as high blood pressure, kidney damage, and reproductive problems3. Testing for lead in the blood can help check for lead exposure, since symptoms can be mild or mistaken for other conditions.
Taking a lead test allows you to be proactive about your health. Some people with high lead levels do not have obvious symptoms. Testing may help identify exposure early, so steps can be taken to reduce further exposure and prevent long-term health problems.

A blood lead test is the most common and reliable method for detecting lead exposure and potential toxicity. It measures the amount of lead currently circulating in your bloodstream.
The frequency of lead testing depends on your risk factors. Those with environmental exposure may need regular testing to monitor lead levels while others may only need a screening. Consult with your healthcare provider for appropriate testing guidance based on your situation.
While you can't undo past lead exposure, you can take steps to reduce further exposure and mitigate its effects. Identifying and removing sources of lead, maintaining a healthy diet, and following medical advice from a healthcare provider can help manage the impact of lead exposure.
