Biomarkers from the earlobe?


Influence of exercise on the immune system and its influence on number and function of immune cells has been studied intensively and changes in leukocyte counts and composition following an acute bout of exercise were repeatedly observed (Nieman, 1997). Up to now venous blood samples were needed to monitor the influence of exercise on the immune system representing an uncomfortable tool in most exercise settings (Simmonds et al. 2011) since it is relatively invasive, requires a trained phlebotomist, and can cause discomfort and may disrupt training (Sitoe et al. 2011). Micro-sampling methods (as earlobe blood samplings) could be considered as a more versatile method in the exercise setting (Canetti et al. 2016) for guaranteeing more frequent sampling time points and consequently a more detailed analysis of the immune response to exercise.
