Blood testing has traditionally been the gold standard for the physiological analysis and monitoring of professional athletes. In recent years, blood testing has moved out of the laboratory thanks to portable handheld devices, such as lactate meters. However, despite its usefulness and widespread use, blood testing has several drawbacks and limitations, such as the need for the athlete to stop exercising for blood extraction and the inability to have data continuously collected.

One clear example is lactate, a relevant biomarker for both sports and health sectors, with a complex sweat-blood bioequivalence. This limitation decreases its individual significance as a sweat-based biomarker.
