Table 3.

Concordance between the reference ranges of the two methods.

All patients (n = 91)		Ion exchange chromatography			Cohen's kappa	p-value
All patients (n = 91)		tHCY < lower limit	tHCY within reference range	tHCY > upper limit	Cohen's kappa	p-value
Immunoassay	tHCY < lower limit	0	0	0	0.565	<0.001
	tHCY within reference range	2	66	4
	tHCY > upper limit	0	7	12

tHCY: total homocysteine.
