Vitamin A Laboratory - External Quality Assurance
Program Information
Key Resources
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. The program assists labs in monitoring the degree of variability and bias in their assays. Information received from the program can then be used to -
- Eliminate bias or precision problems in the assay system.
- Confirm the quality of analysis and increase the confidence level of the lab.
Participation in VITAL-EQA is voluntary and free of charge. Results are not used for accreditation or certification.
