Lead and Heavy Metal Exposure

Magellan Diagnostics' Analytical Services Group (formerly ESA Laboratories) has provided rapid and reliable blood lead and zinc protoporphyrin (ZPP) analysis for over 30 years.  Certified by CLIA and the AIHA Laboratory Accredidation Programs (AIHA-LAP), LLC, we are proud to serve as one of the reference laboratories for the Centers for Disease Control and Prevention (CDC).

Monitoring Exposure in Employees

The Occupational Safety & Health Administration (OSHA) requires monitoring of lead levels by companies whose workers are occupationally exposed.  This includes airborne lead analysis as well as blood lead and ZPP testing.  Companies may also monitor air levels of other heavy metals (e.g., cadmium, zinc, nickel). 

We are experienced in providing rapid, reliable and confidential results to industrial clients.  We are dedicated to the highest levels of personal service, accurate results, and reliable turnaround times.


All testing services are a two-day turnaround (business days), with STAT results available upon request.  For details and pricing, please call 978-250-7150 or email
