Prior to a lactate test, it is wise to practice hygiene so that the samples provided are not contaminated. The subject under study must scrub their hands the same way as a surgeon prepares his hands before an operation. A roll-down test on the trained before the beginning is advisable as well as ensuring that the baseline lactate level does not exceed 1.5 millimoles. If it exceeds, the athlete is advised to rest at around 100 Watts until lactate drops.
