PhenX - selenium protocol 050901

PhenX - selenium protocol

Definition

  • The analytical method for serum selenium (Se) is based on inductively coupled plasma mass spectrometry (ICP-MS) using matrix-matched calibration standards. In this method, Se (isotope mass 78 and/or mass 80), and gallium (mass 69) are measured in serum by inductively coupled plasma dynamic reaction cell spectrometry using methane as reaction gas. Strict adherence to quality control (QC) procedures outlined in the Protocol Text is recommended. Controls should be run at the beginning of the day, and then one control analyzed again after approximately each 10 patient samples, and then all QC controls are run at the end of each day's run. Agreement with certified or accepted QC values should be within the +2 S.D. limits.
