The Sweat Lab

How is my sweat analysed?

The Sweat Lab uses Ion Selective Electrode (ISE) technology with specific proprietary algorythms to determine sodium concentrations directly. We adopt a methodology known as ‘standard addition technique’ which improves accuracy immensely by testing samples 5 times with minute manipulations applied each measurement.

Your sweat sample is analysed by a Lab technician specially trained in this method. Your sample is centrifuged at over 3000RPM to separate all of your sweat sample prior to testing.

ISE is a gold standard method used in research and industry settings. The Sweat Lab has taken further measures to ensure the accuracy of this method working closely with an applications chemist for the best fit to biological testing, namely sweat sodium determination.

Specific regression equations are applied to your sample depending on what body site the sample was taken from (Back, Chest, Forearm, Forehead or Thigh) in order to determine whole body sweat.
