Efficient regulation of zinc homeostasis makes the diagnosis of zinc deficiency and excess difficult, and no single measurement is sufficiently specific or sensitive on its own for this purpose. Dietary zinc content and availability, the prevalence of stunting, and average plasma zinc concentrations in a population could give an estimate of the risk of zinc deficiency. In individuals, plasma zinc concentration, urinary zinc excretion, and the response to an increased zinc intake can provide information about the metabolic state with regard to zinc. Zinc has a low toxicity, but an excessive intake could interfere with copper metabolism.
