Use the MX3 LAB anytime, anywhere. Simply take a quick saliva or sweat sample on the field or in the locker room.


MX3 is scientifically proven to measure biomarkers from saliva as accurately as a laboratory osmometer.


Your hydration level is recorded within seconds of taking a saliva measurement, and results immediately upload to your app.


The LAB can be used over and over by one person or entire teams. Just replace the disposable test strip after each measurement.


Test strips load easily into the LAB, and saliva measurements are made by simply placing the strip on the tip of the tongue.


The LAB can be used with or without Bluetooth or Internet access. Measurements can be taken anytime for immediate readings, then stored for later upload.

Hydration Testing System

The MX3 Hydration Testing System (HTS) uses a single device, the MX3 LAB, to run two different tests in real-time. The HTS not only informs a user how much to drink but what to drink, optimally replacing the correct electrolytes lost during exercise.

Saliva Testing Strip

Hydration Test

A simple saliva test shows any fluid deficit to determine hydration levels and can be compared to an athlete’s Optimal Hydration Zone (OHZ).


Hydrated < 65 mOsm
Mildly Dehydrated 65-100 mOsm
Moderately Dehydrated 100-150 mOsm
Severely Dehydrated > 150 mOsm

Sweat Test Strip

Sweat Test

A sweat sodium test tells an athlete how much sodium one loses in sweat, which is the critical datapoint for determining optimal electrolyte replacement and rehydration strategies.


Low < 750 mg/L
Moderate 750-1100 mg/L
High 1100-1450 mg/L
Very High > 1450 mg/L
