Table V.

Unknown Urine Sample Results (µg/L) by Method (n = 50)

Method	LOD (µg/L)	ULOQ (µg/L)	n > LOD	Measured PHMA (µg/L)
Method	LOD (µg/L)	ULOQ (µg/L)	n > LOD	Minimum	Maximum
A	0.600	100	40	0.607	9.03
B	0.150	100	35	0.202	18.7
C	0.080	120	42	0.094	26.2
D	0.024	100	47	0.035	29.7
E^a	0.200	50.0	45	0.201	16.6

^{^a}

Laboratory E uses a limit of quantitation (LOQ) rather than an LOD. For the purposes of this study, we used their LOQ as the method LOD. ULOQ, upper limit of quantitation.
