title: Interference of gadolinium on the measurement of selenium in human serum by inductively coupled plasma-quadrupole mass spectrometry.
abstract: Selenium is an important clinical biomarker of nutritional status; however, the occurrence of gadolinium in a patient's serum as a result of the contrast agents used during magnetic resonance imaging investigations, results in a significant positive bias in its measurement by inductively coupled plasma-quadrupole mass spectrometry.
