The Impact of Delayed Processing of Chilled Whole Blood Specimens on the Measurement of Nutritional Biomarkers in the United Kingdom National Diet and Nutrition Survey Rolling Programme.

ABSTRACT:

Background

The logistics of timely processing of blood specimens remains a barrier in population health studies to the generation of micronutrient status data.

Objectives

To test a blood specimen processing protocol that includes overnight postage with cooling and its effect on nutritional biomarker concentrations.

Methods

This study was embedded within the United Kingdom National Diet and Nutrition Survey. Paired specimens were collected from 64 participants (16 y+). One set of specimens were processed within 2 h of collection ["field"] and paired samples were mailed in an insulated box with cold packs using an overnight postal service to a central laboratory ["postal"]. Specimen processing protocols were aligned across field sites and the central laboratory. Specime
