Precision of Measuring GMAb Concentration in Human Serum.^*

	Coefficient of variation*			Operator to operator† (Mean + SD)(mcg/ml)
Serum samples‡	Well-to-well	Plate-to-plate	Day-to-day	Operator 1	Operator 2	P value
PAP patient 1	10.3	11.7	11.6	100.4±4.5	97.8±7.0	0.27
PAP patient 2	9.1	8.3	5.4	142.1±12.9	138.4±11.1	0.61
PAP patient 3	4.5	10.0	7.2	24.0±2.5	25.5±2.1	0.47

^*Coefficient of variation was calculated as defined in the methods. Standard deviation × 100 / mean

^‡GMAb concentration of three serum samples were evaluated to validate precision of the assay.

^†GMAb concentration of three serum samples were evaluated by two different operators. Data are expressed as mean.
