520 | _aCurrent chemistry analyzers measure ion concentration using ion- selective electrodes; however, may differ in the specific technology at the bedside versus the central laboratory. Instruments utilized for point-of-care testing (POCT) at the bedside use direct ion-selective electrodes, whereas central-laboratory analyzers use indirect ion-selective electrodes. Under most circumstances, these instruments will deliver the same result; however, various substances can cause interferences in one or the other. An 18-year-old Hispanic woman with a history of immune thrombocytopenic purpura (ITP) presented at Children's National Medical Center (CNMC) with a severe headache and required intravenous immunoglobulin (IVIG) therapy. Because a discrepancy developed between her point-of-care and central-laboratory sodium values, another instrument was used to retest the central-laboratory plasma specimens. The results were more in agreement with those from the point-of-care instrument and revealed a unique interference in sodium measurement related to IVIG use. | ||
