Comments

Analysis for screening only- See patient report. Puncture site must be very clean so specimen does not get contaminated with lead. Adequate sample requires complete filling of at least 2 card circles. Outpatient specimen transport: Mail filter paper cards to the Laboratory per instruction sheet provided in collection kit or send with scheduled courier. Dried spots stable for 6 months, but are discarded in lab after 30 days.
