Other anions such as bromide, iodide and thiosulphate can interfere but usually are not present in high enough concentration to cause significant cross reactivity. A patient from our burns unit had serial chloride measurements on a Radiometer ABL800 blood gas analyser. The results were higher in contrast to plasma measurements on the Abbott Architect Ci8200, which were within reference intervals and in line with the patient's pathophysiological status. This indicated a likely interference with the blood gas analyser chloride estimation. The chloride results on the ABL800 for 3rd, 4th and 5th day after the burn accident were 170, 137 and 119\u2009mmol\/L. Corresponding plasma chloride results on the Ci8200 were all around 105\u2009mmol\/L. Nitrate was found to be markedly elevated in these samples, and the results were 6.7, 4.9 and 1.1\u2009mmol\/L, respectively (reference limit\u2009&lt;\u20090.08\u2009mmol\/L). To further demonstrate nitrate was the causative agent, pooled plasma spiked with 7\u2009mmol\/L of sodium nitrate caused a rise in the ABL800 chloride from 105 to 202\u2009mmol\/L. Later we confirmed that the patient was topically medicated with cerium nitrate cream (Flammacerium\u00ae, Sinclair IS Pharma, UK) for his burns. In summary, the results clearly indicated nitrate was the interferent with the ABL800 chloride estimation and the source was the topical burns cerium nitrate cream.<\/jats:p>","DOI":"10.1177\/0004563214555555","type":"journal-article","created":{"date-parts":[[2014,9,27]],"date-time":"2014-09-27T00:30:28Z","timestamp":1411777828000},"page":"288-292","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Falsely raised whole blood chloride caused by systemic absorption of cerium nitrate cream for burns"],"prefix":"10.1177","volume":"52","author":[{"given":"Leah Y","family":"Ha","sequence":"first","affiliation":[{"name":"Department of Chemical Pathology, Middlemore Hospital, Auckland, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerald A","family":"Woollard","sequence":"additional","affiliation":[{"name":"Department of Specialist Chemical Pathology, Auckland City Hospital, Auckland, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weldon W","family":"Chiu","sequence":"additional","affiliation":[{"name":"Department of Chemical Pathology, Middlemore Hospital, Auckland, New Zealand"},{"name":"Department of Specialist Chemical Pathology, Auckland City Hospital, Auckland, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2014,9,26]]},"reference":[{"key":"bibr1-0004563214555555","volume-title":"Tietz textbook of clinical chemistry and molecular diagnostics","author":"Burtis CA","year":"2006","edition":"4"},{"key":"bibr2-0004563214555555","doi-asserted-by":"publisher","DOI":"10.1016\/0009-9120(94)90009-4"},{"key":"bibr3-0004563214555555","doi-asserted-by":"publisher","DOI":"10.1016\/j.burns.2005.01.014"},{"key":"bibr4-0004563214555555","doi-asserted-by":"publisher","DOI":"10.1016\/j.burns.2005.06.022"},{"key":"bibr5-0004563214555555","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-199603000-00007"},{"key":"bibr6-0004563214555555","doi-asserted-by":"publisher","DOI":"10.1016\/S0305-4179(98)00014-X"},{"key":"bibr7-0004563214555555","doi-asserted-by":"publisher","DOI":"10.1016\/j.burns.2009.07.002"},{"key":"bibr8-0004563214555555","unstructured":"Radiometer M.
