Health Assessment Measurements Quality Assurance Program

Summary

The National Institute of Standards and Technology (NIST) established a Health Assessment Measurements Quality Assurance Program (HAMQAP) to support the measurement needs of the food, dietary supplement, and clinical communities. The HAMQAP concluded in 2021, and parts of the HAMQAP community will now be served through other programs such as ClinQAP, DSQAP, and FNSQAP.

Description

NIST established a Health Assessment Measurements Quality Assurance Program (HAMQAP), in part as a collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS). Participants measured concentrations of nutritional and toxic elements, fat- and water-soluble vitamins, fatty acids, active and/or marker compounds, and contaminants in samples distributed by NIST.   Samples that represent human intake (e.g., foods, dietary supplements, tobacco) were paired with samples that represent human output (e.g., blood, serum, plasma, urine), and analytes were paired where possible to represent the full spectrum of health assessment.  Participant data was compiled at NIST and analyzed for accuracy, precision, and concordance within the community. Reports and certificates of completion were sent to participants.  The HAMQAP, which concluded in 2021, served a wide range of analytical testing communities, previously supported via historical QA programs, such as the Dietary Supplements Laboratory QAP, Micronutrients Measurement QAP, Fatty Acids in Human Serum and Plasma QAP, and Vitamin D Metabolites QAP. New and revitalized programs at NIST will continue to support and serve these measurement communities: ClinQAP, DSQAP, and FNSQAP.
