Plasma copper concentrations are usually low and plasma zinc concentrations high. The aim of this study was to measure the predictive value of this combination of results as a means of facilitating its early diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Low plasma copper (\u22646\u2009 \u00b5mol\/L) and high plasma zinc results (&gt;18\u2009 \u00b5mol\/L) were retrieved from the laboratory database from 2000 to 2014.

Of the five remaining patients, two were treated with zinc because of Wilson\u2019s disease which was the cause of hypocupraemia, two were treated parenterally with zinc, and insufficient information was available in the final patient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The combination of a low plasma copper and high plasma zinc is strongly predictive for the diagnosis of zinc-induced copper deficiency.
