What does the Lead (Hair) test measure?

Q: Why is Lead (Hair) measured?

Hair lead screening may identify chronic environmental or occupational exposure, but clinical decisions—particularly in children and pregnant women—require confirmation with blood lead. Even low-level chronic exposure is associated with neurodevelopmental deficits, hypertension, and renal impairment. Interpretation demands exposure history and correlation with blood testing.

Q: What is the reference range for Lead (Hair)?

The standard reference range for Lead (Hair) is Reference intervals vary; often <3–5 µg/g, but hair lead correlates imperfectly with blood lead, the diagnostic standard.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Lead (Hair) (Pb) is a clinical biomarker used in heavy-metals-toxicology assessment. Lead incorporates into hair during growth and reflects exposure over the preceding months. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Reference intervals vary; often <3–5 µg/g, but hair lead correlates imperfectly with blood lead, the diagnostic standard.
Units: µg/g, ppm
Measured In: 1 test
Category: Heavy Metals

Functional medicine optimalNo safe threshold for lead exposure has been identified; any detectable elevation warrants exposure source identification and mitigation.

What is Lead (Hair)?

Lead incorporates into hair during growth and reflects exposure over the preceding months. Blood lead is the validated marker for systemic burden and neurotoxicity; hair testing is a retrospective exposure indicator and does not replace blood lead in clinical or regulatory contexts. External contamination from environmental dust and occupational sources can inflate results.
