Measurement of free erythrocyte protoporphyrin in blood collected on filter paper as a screening test to detect lead poisoning in children.
A procedure for the measurement of free erythrocyte protoporphyrin (FEP) in a drop of blood collected on filter paper is described. The method is useful as a screening test for lead poisoning in children. Based on the FEP finding and blood lead tests, asymptomatic children are classified into four major categories. A course of action is suggested for each category.
