LOINC long common name : PhenX - selenium protocol 050901;
LOINC short name : PhenX - selenium protocol;
LOINC description : 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.;
