Abstract

The accuracy, reliability and linearity in two hand-portable lactate analyzers, the Accutrend Lactate^® (AL) and the Lactate Pro™ (LP) versus the EBIO^® plus analyzer (EP) were evaluated. For accuracy, duplicate samples recorded on both the AL and LP revealed an overall average difference versus EP (P < 0.05). The limits of agreement between AL and EP were −0.7 to +1.0, and −1.3 to +1.5 mM between LP and EP. Reliability of AL and LP was assessed at different lactate concentrations; coefficient of variation ranged between 1.8 and 3.3% for AL and between 2.8 and 5.0% for LP. AL and LP had a good reliability for intra-, inter-analyzers, and between test strips (ICC r = 0.999). The linearity was determined versus the EP as reference. The slope coefficient of AL (1.0394) was closer to 1 than that of LP (1.1053). On these bases, AL and LP can be individually considered suitable for the sports research field.
