The Childhood Lead Poisoning Laboratory analyzes children’s blood specimens for lead for screening (capillary) and diagnostic (venous) purposes. The laboratory also analyzes environmental samples for lead content including water, air, paint chips, dust wipes, toys and other potential sources of exposure. Most specimens are submitted by county health departments, as part of public health investigations of lead poisoning.
The laboratory is CLIA certified (33D0654341) for clinical testing and holds a NYS DOH Clinical Laboratory Permit CLIA# 33D0654341 and PFI# 1067 in the category Toxicology Blood Lead – Comprehensive. The laboratory is fully certified under NELAP standards for environmental testing by both the NYSDOH (Lab #10762) and by the State of Florida (E37911).
Lead Analysis/tests routinely performed:
- Blood: performed as a diagnostic test on venous blood, or as a screening test on capillary blood specimens, using Graphite Furnace Atomic Absorption Spectrometry.
- Soil: performed for county health units as a supporting test to identify potential sources of lead exposure in confirmed lead poisoning cases.
- Paint: performed on paint chips for county health units as a supporting test to identify potential sources of lead exposure in confirmed lead poisoning cases. The method involves digesting paint chips in strong acid and measuring lead by Flame Atomic Absorption Spectrometry.
- Dust: performed on dust wipes for county health units as a supporting test to identify potential sources of lead exposure in confirmed lead poisoning cases. The method involves digesting dust wipes in strong acid and measuring lead by Flame Atomic Absorption Spectrometry.
Academic Programs: Senior laboratory scientists hold academic appointments in the Department of Environmental Health Sciences of the University at Albany’s School of Public Health. The laboratory hosts both doctoral (PhD) and masters (MS, MPH) students working toward degrees awarded by the University at Albany in the Department of Environmental Health Sciences (EHS). Staff members co-teach several graduate courses (core and electives) that are required for completion of the degree. They include EHS 525 Environmental Chemical Analysis, EHS 530 Principles of Environmental Chemistry, EHS 530 Principles of Toxicology, and EHS 621 Chromatographic Methods. Opportunities for high school students, graduate students, postdoctoral fellows, chemist aides, and laboratory technicians are available, along with access to state-of-the-art instrumentation.
