Use and Clinical Application Humans are continuously being exposed to metals within the atmosphere. High-dose exposures of some of these metals, such as lead, mercury, arsenic, and cadmium, can cause clinical toxicity [1]. Assessing human exposure to metals is crucial to characterizing the hazard; assessment can be accomplished by evaluating the environmental source of your exposure, such as air, water, or food, or by evaluating the quantity of the metal absorbed by the physique. The quantification of chemicals or their metabolites in clinical specimens, such as blood and urine, by using instrumental evaluation in the laboratory is referred to as biomonitoring [4]. Biomonitoring might help diagnose, treat, and monitor sufferers and populations for illnesses and problems caused by exposure to harmful chemicals. Inside the clinical setting, laboratory tests are applied in conjunction together with the patient’s history, situations surrounding the well being concern, along with the physical examination to diagnose ailments or disorders and make recommendations for the patient. In a population, laboratory tests may be employed inside the management of illnesses and disorders by monitoring modifications in trends following an intervention, for instance pharmacotherapy or cessation of further exposure to a chemical. Also, biomonitoring can characterize the prevalence of precise chemical exposure within a population, identify groups in the population with varying levels of exposure to a chemical, and assist with prioritizing investigation activities when sources are restricted. The Environmental Well being Laboratory at the Centers for Illness Control and Prevention (CDC) supports a National Biomonitoring System that develops analytical procedures to measure metals including mercury (total and speciated), arsenic (total and speciated), cadmium, lead, cobalt, tungsten, uranium, molybdenum, antimony, and other trace, toxic, and necessary metals. For every of those metals, CDC estimates their concentrations in blood or urine in the common U.S. populationKeywords Analytical method . Clinical laboratory . Blood . Urine . Metals .
