Programs
Performance Verification Program for the Folate Microbiologic Assay
The Performance Verification Program for the Folate Microbiologic Assay assesses the performance and continued proficiency of regional resource laboratories engaged in public health work. The program uses 40 serum and/or whole blood samples analyzed in one year.
Performance Verification Program for Serum Micronutrients
The Performance Verification Program for Serum Micronutrients assesses the performance and continued proficiency of laboratories engaged in public health work. The program uses 40 serum samples analyzed in one year.
Vitamin A Laboratory – External Quality Assurance (VITAL-EQA)
The Vitamin A Laboratory – External Quality Assurance (VITAL-EQA) program is a standardization program designed to provide labs measuring nutritional markers in serum with an independent assessment of their analytical performance.
Quality Control Materials for Serum or Whole Blood Folate
Quality Control Materials for Serum or Whole Blood Folate offers sets of value assigned serum or whole blood quality control (QC) materials for folate status biomarkers.
Quality Control Materials for Serum Micronutrients
Quality Control Materials for Serum Micronutrients offers sets of value-assigned serum quality control (QC) materials. These materials have been characterized for biomarkers of water-soluble and fat-soluble vitamins, iron status, and inflammation status.
Folate Harmonization for Public Health Laboratories
Folate Harmonization for Public Health Laboratories offers support and materials to laboratories conducting the folate microbiologic assay for epidemiologic use in population surveys.
Technical Assistance for Micronutrient Surveys
Technical Assistance for Micronutrient Surveys provides training and technical assistance to international public health organizations on sample analysis and field logistics for national nutrition surveys.
