How is sample collected for lead poisioning detection?
Lead poisoning can be screened & confirmed in two ways: Venipuncture and Capillary testing. Venipuncture is puncture of a vein through the skin in order to withdraw blood for analysis and is more preferred for specimen collection over the capillary testing as the later is prone to contamination because of the possibility of lead containing dust and dirt on the hand or under the fingernails.
