Microlife MedGem Metabolism-Based Weight Management Solutions

Microlife MedGem indirect calorimeter to measure RMRThe MedGem RMR indirect calorimeter is a clinically-validated and FDA 510K-cleared, class II, medical device for measurement of patient resting metabolic rate (RMR).

Instead of estimating RMR with the Harris-Benedict or Katch-McArdle formula, the MedGem scientifically measures a clients Metabolic Fingerprint, that is unique to them.

Estimation formulas cannot factor in thyroid issues, the effects of medications, etc.

For the best care, the American Dietetics Association recommends using indirect calorimetry to measure RMR for the most accurate assessment of nutritional needs.

The MedGem is the same type of indirect calorimeter as the BodyGem, but it’s designed for professionals who need an FDA-approved device, to make insurance claims.

It’s Simple – To perform a measurement, your client simply breathes into the MedGem, which measures their oxygen consumption (VO2), the resulting RMR number is clearly displayed on the device’s LCD screen.

It’s Accurate – The MedGem has been validated against the gold standard Douglas Bag, and other commonly used metabolic carts

It’s Convenient – The MedGem comes with a portable carry case, it’s self-calibrating, easy to administer, and provides a result in 10 minutes or less.

It’s Affordable – The MedGem is available in different measurement capacities to ensure your organization has the right device for your needs.
