Test Method

Principle : Competitive type immunoassay with chemiluminescence detection (improved biotin assay)

Reagents: Roche Elecsys Folate III

Analyser: Cobas e801

Uncertainty of Measurement

Uncertainty of Measurement: 2 nmol/L at a concentration of 7 nmol/L 12% at concentrations of 15 nmol/L and higher Haemolysed specimens may spuriously elevate the serum folate result.
