"The results of this preliminary evaluation show that the results produced by the Lactate Pro appear to be homeoscedastic (ie there appears to be no obvious relationship between the degree of disparity between analysers and level of lactate measured).

This is in contrast to the Accusport Lactate Meter, which exhibits a degree of heteroscedasticity where values in excess of 8mM appear to be substantially lower than in other analysers and this difference increases with increasing levels of blood lactate concentration.

The Lactate Pro requires a sample size of only 5 µl and does not require pipetting of blood onto the reagent strip. This eliminates the potential mental error related to pipetting and facilitates a more rapid measurement. Initial indications are that the Lactate Pro can analyse a sample and displays the result approximately 30 seconds more quickly than the Accusport."

"In summary, this evaluation has shown that the Lactate Pro exhibits a high degree of accuracy with other lactate analysers, good reliability and a high degree of versatility under a variety of testing conditions."
