Diagnosis and detection of deficiencies of micronutrients: minerals.
Determination of the presence or absence of a deficiency of one or more of the micronutrient minerals (usually described as trace elements) can be a complex problem, frequently requiring the integration of clinical, nutritional and biochemical data. Almost invariably, laboratory investigations are required and this short review describes the more common techniques applied for the various essential trace elements. Using a combination of techniques it is usually possible to determine, with confidence, whether an individual subject or small groups of subjects have a deficiency of a specific trace elements, but simple reliable tests which can be used in population studies are still lacking for several key elements. This problem appears most acute for studies of chromium, copper and zinc, deficiencies of which may have important roles in the pathogenesis of a variety of human disorders.
