TABLE 3.

Statistical evaluation of the quality of resazurin and XTT assays^a

Assay	Z′ factor	C_v (%)^b	Linearity (R²)^c
Resazurin	0.9 ± 0.02	7.6 ± 0.35	0.995
XTT	0.89 ± 0.1	2.4 ± 0.54	0.983

Ideal HTS parameters are a Z′ factor of >0.5 (74) and a C_v of <10% (30).

C_v %, coefficient of variance of cell controls.

Linearity of the dye reduction-versus-parasites/well curve.
