• Error: Bad/Used test strip

  This error occurs when the LAB detects a faulty or used test strip.
  This most commonly occurs when you have failed to eject the test strip after taking a measurement and have attempted to take another measurement.
  This may also happen when test strips have been exposed to water or very high humidity for extended periods of time.
  In all cases, discard the test strip and repeat the measurement using a new test strip.

• Error: Test Strip Removed too early

  This error occurs when the test strip is ejected before the measurement has finished.
  Make sure that the test strip is not ejected until the LAB beeps a second time and the result is displayed.

• Error: Bad Reading

  This error occurs when the MX3 LAB detects that the measurement is faulty.
  This is typically due to collection of bubbles in the test strip, excessive saliva covering the test strip exit pore or due to contamination with recent food or drink
  If you are seeing many bad readings, please review the sample collection guide in the MX3 Hydration Testing System User Manual or contact MX3 Support for assistance.

SOSM Measurements

Salivary osmolarity (SOSM) reflects the concentration of electrolytes and other solutes in saliva. SOSM has been identified as a non-invasive measure for monitoring of hydration status. Multiple studies have shown that increases in SOSM during exercise are a more accurate measure of active dehydration compared to urine testing.

• What does a SOSM result mean?

  In basic terms, SOSM values increase as dehydration increases, and they decrease as hydration status improves (so higher number = more dehydrated). Most users will exhibit a gradual increase in SOSM as they work or exercise. The MX3 Hydration Testing System classifies hydration status into four possible categories: hydrated, mildly dehydrated, moderately dehydrated and severely dehydrated, based on the SOSM reading and, if determined, the user’s optimal hydration zone.

• What is an Optimal Hydration Zone?

  The optimal hydration zone (OHZ) is a personalized SOSM target range that reflects a user’s fully hydrated state. The OHZ is determined by conducting a series of baseline measurements in a fully hydrated state achieved with a multi-day hydration protocol involving consistent fluid intake. The OHZ is used by the MX3 App to determine a user’s specific SOSM hydration status thresholds and provide a target range for rehydrating after work or exercise.

   

• How should I use MX3 Hydration Measurements?

  For information on how to interpret measurements see the MX3 Hydration Testing System User Manual.

   

• Will food or drink alter an SOSM measurement?

  Yes, eating or drinking immediately before taking a measurement can impact the SOSM score or cause a measurement error. We recommend a user wait at least five minutes after eating or drinking before taking a measurement. If there is substantial food debris within a user’s mouth, we recommend rinsing with water and then waiting five minutes.

• Is my measurement data saved?

  Measurements taken on the LAB while paired with the MX3 App are automatically saved for later analysis in the MX3 App and MX3 Portal. If you take an SOSM measurement with the LAB in LOCAL mode, then the hydration score will not be stored and will need to be manually recorded.

• Can I export my SOSM measurement data to use in another program?

  Yes. The measurement data (list of hydration scores) can be exported from the MX3 App or the MX3 Portal for external analysis or for logging in another user management platform.

• Why do I see different SOSM values when I take multiple readings?

  Each saliva sample is a complex combination of saliva from different salivary glands. It is normal to see a small amount of variation from reading to reading, even when these are taken only a few seconds apart. This variability does not prevent assessment of hydration status as true dehydration effects are usually represented by much larger increases in SOSM.
  It is important to have a consistent methodology when making SOSM measurements. More information can be found in the sample collection guide in the MX3 Hydration Testing System User Manual.

   

• How accurate is SOSM as a measure of hydration?

  For a detailed technical summary please contact MX3 Support for a MX3 technical validation document.

The MX3 LAB

The MX3 LAB is a powerful handheld device capable of laboratory-grade analysis. Simply insert a test strip, take a small saliva sample and get your actionable results in seconds.

• Do I need to calibrate the MX3 LAB?

  No! The MX3 LAB is automatically calibrated by the MX3 Test Strip and the MX3 App. No calibration strips or solutions are needed. However, if you primarily use the MX3 Lab in LOCAL mode you may be required to occasionally sync with the MX3 App to update to the latest calibration data.

• Do I need a phone to use the MX3 LAB?

  No! We recommend you use the MX3 LAB paired with the MX3 App, as it allows you to track and analyze past measurements and personalize measurement results. However, the MX3 LAB may also be used independently, with results displayed directly on the MX3 LAB. However, once the test strip has been removed there is no way of viewing past results, so the result should be recorded prior to discarding the test strip.

• How do I charge the MX3 LAB?

  The MX3 Lab can be charged with most standard USB-C charging cables. The MX3 LAB will typically charge fully in less than 3 hours when connected to a computer USB port or USB power adapter.

The MX3 Hydration Test Strip

• Do MX3 Hydration Test Strips have a use-by-date?

  MX3 Hydration Test Strips should be stored in cool and dry conditions, used within 24 months of manufacturing and 30 days after opening. After this date, test strips may still function, but may have reduced accuracy, precision and flow time.

• Are MX3 Hydration Test Strips safe?

  Yes. MX3 test strips are treated with high-dose gamma irradiation following packaging to ensure sterility. Independent laboratory testing has shown that MX3 test strips are non-toxic following cellular toxicity testing.

The MX3 Sweat Test Kit

• Do I need an MX3 LAB to use the MX3 Sweat Test Kit?

  Yes, you will need an MX3 LAB to perform sweat measurements. If you already have an MX3 LAB, purchased as part of the MX3 Hydration Testing System, it will be able to perform MX3 Sweat Tests. You may need to update to the latest firmware through the MX3 App. You may also purchase a separate MX3 LAB for use with MX3 Sweat Test Kits.

• Can I perform an MX3 Sweat Test without the MX3 App?

  No. At this time MX3 Sweat Tests must be performed while paired with the MX3 App. If you are unable to use the MX3 App at the time of sample collection, the sweat sample may be stored in the provided tube for up to 24 hours before measurement.

• Can I order replacement components if I made an error during sample collection?

  At this time individual Sweat Test Kit components cannot be purchased from MX3.

  Please contact MX3 Support for assistance.

The MX3 Dispenser

The MX3 Dispenser stores up to 45 sterilized test strips. It provides a clean, easy to use, solution minimizing potential contamination from manual handling.
