Selenium Test
The selenium test measures the concentration of selenium in a serum sample. Quest describes it as useful for monitoring selenium status related to parenteral nutrition and certain special diets.
About this test
This test measures the concentration of selenium in a 2 mL serum sample, collected in a no-additive (royal blue-top) trace-element tube and analyzed using Inductively Coupled Plasma/Mass Spectrometry (ICP/MS).
Quest describes selenium monitoring as useful in assessing parenteral nutrition, particularly recent intake, since selenium is one of the elements included in parenteral nutrition formulas. It is also monitored in children with propionic acidemia who require special diets with supplements.
Who might consider this test?
- Often being monitored in the context of parenteral (IV) nutrition
- Are following a special diet that a clinician is tracking with supplement levels
- Such as in propionic acidemia

What this test looks at
The result is a single measurement: the concentration of selenium in serum. Because selenium levels can be affected by recent supplement intake, Quest's preparation instruction asks that vitamin or mineral supplements be avoided for a few days before the draw.
