What is measured?
Indication(s)
Assessment of vitamin E status.
Specimen, collection and processing
Patient/subject: Over night fasting is recommended.
Matrix: Serum or EDTA plasma.
Volume: Minimum volume is 50 µL, but 200 µL is optimal and allows reanalysis.
Preparation and stability: Serum gel tubes must not be used. Samples should be put on ice, and protected from light.
Transportation
Protected from light, frozen, on dry ice (for general instruction on transportation, click here)
Reported values, interpretation
Reported values (aToc/gToc): 11-106/0.5-11 µmol/L.
Intraclass correlation coefficient (ICC) (aToc/gToc): 0.86/na.
