Why Is This Test Done?
Your healthcare provider may order this test if you have symptoms of lead poisoning (like headaches, fatigue, or behavioral changes), if you work in an environment with lead exposure, or if you live in an area with contaminated water or dust. It’s also part of routine screening for children in certain high-risk groups.
What Does the Test Involve?
You’ll have a small needle inserted into your arm to draw a small amount of blood. The blood sample is then sent to a lab for testing. The test usually takes a few minutes, and you may feel a slight pinch or discomfort during the draw.
What Are Common Results?
Results are typically reported in micrograms per deciliter (µg/dL). Higher levels may indicate exposure to lead, which can cause health problems. Your doctor will interpret the results in relation to your symptoms and medical history.
What Are the Risks?
The main risk is a minor bruise, swelling, or slight pain at the needle insertion site. Rarely, there may be a reaction to the blood draw, such as fainting or a slight allergic response.
Reference range
Adult males: 4.2-5.9; Females: 3.8-5.1 x 10^12/LN/A
