Characteristics of the analysis

Component	LOD (mmol L−1)	CV (%)	Sample volume (μL)
Sodium	0.4	< 1	15
Chloride	0.4	< 2.2	15
Potassium	0.2	1.0–1.3	15
Ammonia	0.0001	3.1	20
Lactate	0.2	< 3.6	2
Glucosesweat	–	–	2
Glucoseblood	0.11	0.7	2

Glucose concentration in sweat was determined with a dynamic multiple reaction monitoring method (described in Supplemental Procedure), which is not a routine analysis and, therefore, characteristics are not known
