Filter paper lead testing.
Lead is a common toxic metal in our environment. It is present at high concentrations (up to 600 g/kg) in some paints manufactured before 1970. Some artistic ceramic products and leaded glass contain substantial amounts of lead that can be leached by weak acids such as vinegar and fruit juices. Lead is also found in dirt from areas adjacent to buildings painted with lead-based paints and on hig...
متن کاملFilter paper-collected blood lead testing in children.
To the Editor The Editorial " Filter Paper Lead Testing " by Moyer et al. (1) repeats previously raised hypothetical and unsubstantiated claims on filter paper (FP collection-based) blood lead testing (1– 4). All the theoretical charges were appropriately rebutted in the past based on published evidence (5–9). The peer-reviewed scientific literature supports the clinical usefulness of FP-collec...
متن کاملEvaluation of filter paper blood lead methods: results of a pilot proficiency testing program.
BACKGROUND Lead testing on dried filter paper (FP) blood spots is used routinely by some laboratories for lead poisoning screening. Proficiency testing (PT) as required under CLIA '88 laboratory regulations has not been available for these methods. METHODS We describe a suitable PT scheme and evaluate FP laboratory performance based on program results. Monthly testing events consisting of fiv...
متن کاملutility of filter paper for preserving insects, bacteria, and host reservoir dna for molecular testing
background : appropriate methodology for storage biological materials, extraction of dna, and proper dna preservation is vital for studies involving genetic analysis of insects, bacteria, and reservoir hosts as well as for molecular diagnostics of pathogens carried by vectors and reservoirs. here we tried to evaluate the utility of a simple filter paper-based for storage of insects, bacteria, r...
متن کاملProcedures for testing urine specimens dried on filter paper.
METHOD for collection of urine from infants onto squares of filter paper was described as part of a program for early detection of phenylketonuria (1). These urine papers have proved extremely versatile as an aid to testing urine for a number of substances that are excreted as a result of certain metabolic defects, all easily detectable by simple means. Phenylpyruvic acid, phenylalanine, and oh...
