Hair vs. serum mineral analysis as a diagnostic tool

Traditional equine diets often don’t meet the horse nutritional requirements, causing mineral imbalances and other disorders. Mineral elements undergo homeostatic controls in the blood, and thus routine serum analysis usually won’t indicate sub-clinical conditions. However, hair analysis, known as a possible non-invasive biomarker for mineral status in humans, may serve better, being a metabolically inactive tissue, which tends to accumulate minerals.

Hair mineral analysis results showed a significant affect in all treatment groups, while Serum mineral analysis showed no significant affect, apart from copper and strontium. 

Expert opinion by Shirley Ferber

These results strengthen previous data on hair and serum mineral elements concentrations. Indicating hair analysis as a valid diagnostic tool for veterinarians and nutritionists, and perhaps a better biological indicator for mineral status in horses. Although, as suggested by the author, future research is needed to determine reliability.
