🔍 What is the Lead Blood Test?
The Lead Blood Test measures the amount of lead in the bloodstream to detect lead poisoning or exposure to lead-based materials. Lead is a toxic metal that can accumulate in the body through contaminated water, food, air, or old paints, posing serious health risks.
🎯 Purpose of the Test
Detect lead poisoning in adults and children
Monitor occupational exposure to lead
Evaluate symptoms like fatigue, memory loss, and abdominal pain
Assess treatment effectiveness during chelation therapy
📊 Normal Ranges & Result Interpretation (May vary by lab)
Category
Blood Lead Level (µg/dL)
Interpretation
Normal
<5 µg/dL
No significant exposure
Elevated
5 – 9 µg/dL
Mild exposure, requires monitoring (especially in children)
Moderate Toxicity
10 – 19 µg/dL
Increased risk of health issues, needs medical evaluation
Severe Toxicity
≥20 µg/dL
Immediate medical intervention required
⚠️ Health Effects of High Lead Levels
Children: Developmental delays, learning disabilities, irritability
Adults: High blood pressure, kidney damage, memory loss
Pregnant Women: Risk of miscarriage, premature birth, or birth defects
Long-Term Exposure: Nervous system damage, anemia, and reduced fertility
📝 Additional Testing May Include:
Zinc Protoporphyrin (ZPP) Test (long-term lead exposure)
Urine Lead Test (for recent exposure)
Kidney Function Tests
Complete Blood Count (CBC)
