Point-of-Care device for quantification of zinc in serum.

With 42,000 cases reported annually in the United States and an approximate 10% mortality rate, [1] pediatric septic shock is a major health problem that is often difficult to treat effectively. Several studies have shown that children experiencing pediatric septic shock often have critically low levels of serum zinc (Zn), suggesting supplementation of Zn to be an effective therapeutic strategy. However, to protect the safety and well-being of the patient, it is extremely important to monitor blood serum concentration of Zn during supplementation in order to ensure that levels remain at or near the physiological norm and thus minimize the risk of heavy metal toxicity from over supplementation.
