Whole blood required - DO NOT SPIN
Dedicated sample preferred
Units : nmol/g Hb
Reference interval : 4.0 to 15.0 nmol/g Hb
Uncertainty of measurement : 15%
Inductively-coupled plasma mass spectrometry (ICPMS)
RBC selenium (Se) has the advantage over plasma Se in that its concentration is unaffected by the acute phase response to inflammation.
In contrast, plasma Se may be decreased in states of infection, illness, inflammation or trauma, which may give a false impression of Se deficiency.
