Precision of folate analysis by trienzyme extraction-L. casei

Parameters1)	Folate content (μg/100 g)
	Repeatability2)	Reproducibility3)
	Mean±SD	180.39±3.91	183.64±2.69
CV (%)	2.17	1.47

n=5 in triplicates; SD=standard deviation; CV (coefficient variation)=100×(SD/mean)
Repeatability refers to the results of five independent determinations (triplicates each) of folate in a QC sample performed in a day.
Reproducibility refers to the results of five independent determinations (triplicates each) of folate in a QC sample performed once a day for five different assay days.
