Hydration Testing:
The Power of a Lab
In the Palm of Your Hand

Test Hydration Anywhere, Anytime

Hydration is essential for health and performance. Many hydration testing techniques are inconvenient, inaccurate or invasive. Assessing hydration status with the MX3 Hydration Testing System is fast and reliable. Sample collection, measurement and disposal are much more convenient than urine testing or nude body mass measurements, and sample integrity is ensured by performing direct from the mouth measurements.

Why Salivary Osmolarity?

Testing salivary osmolarity is the only field-accessible hydration testing method that can test for both acute and chronic dehydration.

Saliva Osmolarity: MX3 LAB vs Laboratory Testing

Testing SOSM with the MX3 LAB is faster and more convenient than using a Laboratory Osmometer. SOSM values with the MX3 LAB have an excellent correlation with laboratory measurements.
