CDC's Division of Laboratory Sciences coordinates the National Biomonitoring Program (NBP) which offers an assessment of nutritional status and the exposure of the U.S. population to environmental chemicals and toxic substances. Through biomonitoring we can understand
- the environmental chemicals to which people have been exposed,
- the amounts of chemicals that are actually in people's bodies, and
- people's nutrition status by measuring indicators such as iron and folate
Measurements by the National Biomonitoring Program are used to improve the detection, diagnosis, treatment and prevention of disease, injury, and harmful exposures in populations.
