Testing Services

At Houston Family Nutrition, we offer a variety of testing to help meet your health needs. We have partnered with Composition ID for DEXA scans, RMR, VO2 Max, as well as third party labs for blood-work.


A DEXA (Dual Energy X-ray Absorptiometry) scan is a safe and accurate way for you to discover your body health metrics. In a non-invasive way, you will be able to learn your fat mass, lean mass, and bone mineral density. This scan will allow you to see how your fat mass and lean mass is broken down across different regions of your body, and you will also be able to view a comparison of the lean muscles between your left and right sides.  

How the Test is Conducted: You will lie on your back on a table above the x-ray generator, which will take images of different parts of your body.

With a DEXA Scan, you will be able to determine:

  • Your total body fat percentage
  • Your risk for osteoporosis and osteopenia 
  • Your body’s regions of concern 
  • Any muscular imbalances due to injury or overuse
  • Any potential health risks that you did not anticipate

RMR Test (Resting Metabolic Rate)


The RMR (Resting Metabolic Rate) test measures the amount of energy your body burns at rest. This information is helpful in determining the amount of calories you should consume for gaining weight, maintaining weight, weight loss and what you should not go under for optimal metabolic health. 

How the Test is Conducted: During a 10-minute rested breath test, the equipment will determine your RMR by calculating how many calories your body burns while you are doing absolutely nothing.

With a RMR Test, you will be able to determine:

  • The number of calories your body burns at rest
  • How many calories you should consume for maintaining weight, losing weight, and medically supervised zones
  • How long it would take you to reach your goal weight when following your custom calorie intake
  • Where your metabolism lies (slow, normal, fast)
  • How your metabolism compares to others 

Cost: $110

Vo2 Max

The VO2 Max (Maximal oxygen uptake) test measures the maximum amount of oxygen your body can use during an intense exercise. It is an accurate and effective way of telling us about your cardiovascular fitness and performance capacity. 

How the Test is Conducted: During the test, you will run at different intensities and speeds, and the equipment will analyze your breath to measure how much and at what rate your body is using up oxygen.

With a VO2 Max Test, you will be able to determine:

  • Your baseline fitness level
  • Your heart rate training zones for tailoring your workouts to receive maximum gains
  • Your aerobic, anaerobic, and lactate threshold zones
  • How to effectively increase your VO2 aerobic capacity

Cost: $125
