Biological sample collection and handling methods for fat-soluble vitamin and trace mineral analysis

Abstract

Diagnostic reports of biological samples submitted from farms are essential to correctly identify any underlying issues in a herd, including disease and improper nutrition. Proper sample collection, handling, and storage are critical to most accurately diagnose health complications or nutritional status. When possible, sample pigs before they eat, keep tissue samples frozen, avoid hemolyzed blood samples, and minimize transport time to the diagnostic laboratory. Concerns regarding sample collection and storage can be addressed with a veterinary diagnostic laboratory.
