Microlife BodyGem and MedGem indirect calorimeters

Microlife MedGem FDA Cleared Indirect Calorimeter

Microlife MedGem Indirect Calorimeter for RMR - Resting Metabolic RateThe MedGem indirect calorimetry device is a clinically-validated and FDA 510K-cleared, class II, medical device for measurement of patient resting metabolic rate (RMR).

The MedGem is an easy-to-use, handheld device that accurately measures oxygen consumption (VO2) to determine resting metabolic rate (RMR)*.

Measurements made with the MedGem are easy to administer and provide accurate results in only a few minutes.

Microlife’s WatchWT MedGem device was used to assess metabolic changes in The Biggest Loser™ contestants. “We chose to use the MedGem device based on its accuracy in comparison to other indirect calorimeters.” said Dr. Robert Huizenga, Associate Professor of Clinical Medicine at UCLA and Medical Advisor to The Biggest Loser.

Rates range from $60 – $80 in total (Pt. Co-pay + reimbursement).  CPT Code 94690 (oxygen uptake) is a pulmonary code therefore it is suggested that supporting ICD-9 codes be pulmonary in nature.

We offer two types of MedGem System Kits to meet your needs:

The MedGem WatchWT System Kit is $3,499. It includes:

♦ MedGem indirect calorimeter with a 2-year warranty
♦ One 21-pack mouthpiece filters and nose clips
♦ MedGem Analyzer software for Windows
♦ A lightweight carrying case
♦ A metabolic rate and weight management program implementation guide
♦ A marketing materials kit with trifold brochures

The MedGem System Kit is the best long-term system for people who offer a lot of measurements, because it has the lowest per-use cost.

The sensor does not need to be replaced. To continue providing measurements, all you need is additional mouthpiece filters and nose clips.

21-packs of mouthpiece filters and nose clips are $299.

You can extend the MedGem System Kit two-year warranty to three years for $295.

If you have a problem with the device after the warranty has expired, you can get it evaluated and recalibrated in our repair facility for $99 plus return shipping costs.

MedGem Starter System Kit is $1,099. It includes everything you need to administer 42 measurements.

♦ MedGem indirect calorimeter that’s setup to complete forty measurements
♦ MedGem Analyzer Software for Windows
♦ 42 mouthpiece filters and nose clips
♦ A lightweight carrying case
♦ A marketing materials kit with trifold brochures

It uses the same FDA-approved MedGem device, but is programmed to complete only 40 measurements, which allows us to offer it at a lower price point.

The MedGem Starter Kit is a great entry level system if you have low volume or don’t have the budget to purchase the regular System Kit.

When your forty measurements are complete you can send your device to us to get it reprogrammed for 42 more measurements and sent back with 42-filters for $999, to continue testing. You’ll need an RMA number for this service, so that we can track it properly.

Licensed clinicians typically charge between $70-90 for a RMR measurement, so the MedGem Starter Kit allows you to generate between $2,800 – $3,600 in revenue.

  1. No, it’s not designed to work with patients who are ventilated as it’s a hand held device with a mouthpiece filter. Other manufacturers make indirect calorimeters that use hoses that may be able to connect properly to the ventilator.
