Body Composition Analysis
Pre-Test Guidelines

Things to keep in mind for an accurate measurement:

The accuracy of our body composition analyzer is dependent in part on the client and the environment in which the test is conducted.  Certain precautionary steps should be taken in order to assure accurate results.  Before setting up your appointment please read through the following steps very carefully.  Then schedule your testing appointment appropriate to meet these guidelines.   
If you have any questions please phone Suzanne at 925 838-1000.

1. Assure that the test is conducted before a meal 
In cases where the client has already eaten, the test should be put off until two hours have elapsed since the last meal.  This is because the mass of the food is counted as weight, and thus, may result in measurement error. 

2. Make sure to use the bathroom
Although not included in the body’s compositional elements, the volume of urine and excrement is included in the weight measurement.  This can cause incorrect readings.

3. Do not exercise right before the test.
Strenuous exercise or dynamic movements can cause temporary changes in body composition. Try to test approximately two hours after exercise or better yet, test before exercise.

4. Stand still for about 5 minutes
Conducting the test immediately after lying in bed or sitting for a long period of time might result in a slight change in the test results.  This is because body water tends to move to the lower extremities of the body as soon as a person stands or gets up.

5. Do not conduct the test right after a shower or sauna
Sweating causes temporary changes in a person’s composition.

6. Do not take measurements during the menstrual cycle
Females experience increases in body water during their menstrual cycle.

7. Conduct the test at normal temperature (68-77 degrees)
While the human body is stable at normal temperatures, body composition is susceptible to change in hot or cold weather.

8. Wear minimal clothing (guys: light t-shirt or no shirt and shorts, ladies: sports bra or light t-shirt and shorts).

9. If a retest is scheduled, make sure to conduct the test under the same consistent conditions as the pre-test (i.e. same clothing worn). Identical conditions need to be maintained in order to assure the accuracy of the test results.
