Questions about performing a BIA test

• Should the test subject lie down to be tested?

  All research has been performed with the subject lying flat with legs apart and arms not touching the body, therefore it is recommended that the test subject lie down to be tested.

• What side of the body is used for BIA testing?

  The right side of the body is commonly used for BIA testing. However, the left side of the body may be used if necessary. It is important to be consistent and use the same side on a test subject for repeatability.

• Can you feel the test while it is being performed?

  No, the current passed through the body is so small that it is unlikely it will be felt at all!

• How long does it take to perform a BIA test on a subject?

  Typically, the test will take approximately five minutes.

• What electrodes can be used for testing?

  RJL Systems, Inc. (RJL) suggests that the tests be performed using the adhesive electrodes supplied by them. RJL cannot guarantee accurate test results acquired by using other electrodes.

• Do I have to use new electrodes for every test subject?

  Yes, for accuracy, and above all, for sanitary reasons, new electrodes should be used for each test performed.

• Can the age of electrodes affect results?

  Yes, RJL electrodes have a shelf life of 14 to 16 months. Expired electrodes will produce inaccurate results. As well, if electrodes are not kept in a sealed bag or container, they can dry out and also produce inaccurate results.

• Is there anything particular that the test subject should do prior to being tested with the RJL Analyzer?

  The test subject.s body should be dry; no fever should be present, and should not be chilled or cold. Please review .Subject Protocol. on the .Electrode Placement. card.

• Could very dry or very oily skin affect the BIA readings?

  Yes. Good contact between the skin and electrodes must be made for accurate results. If a person.s skin is oily, wipe the area with an alcohol swab before positioning the electrodes. If the skin is very dry, use an electrode gel.

• Do women have to remove their nylons before testing?

  Yes, the adhesive electrodes must make direct contact with the skin for an accurate measurement.

• Will jewelry affect the BIA test?

  No, there will be no affect on the BIA test provided the jewelry does not interfere with electrode placement. However we recommend that all jewelry be removed.

• Do pins in a subject.s arms or legs affect the BIA readings?

  No, pins in a subject.s arms or legs will not affect the BIA readings.

• Can people with pacemakers be tested with the RJL analyzers?

  No, people with implanted electronic devices such as pacemakers or defibrillators should NOT be tested due to the possibility of interference of the BIA signal with the defibrillator.

• Will medication affect the reliability of the BIA test?

  Changes in the results may come from medications, disease and nutritional status. BIA results quantitatively illustrate all of these factors and conditions. That's what BIA is all about!

• Can obese or emaciated test subjects be tested with the RJL analyzers?

  Yes, and serial testing will reflect changes in a person's body composition.

• Can pregnant women be tested with the RJL analyzers?

  No.

• At what age can children be tested?

  Equations were developed on children beginning at age 8. However, people of any age may be tested for resistance and reactance results.

• Are medical professionals the only people that should perform the BIA test?

  No, anyone that has been properly trained can perform the test. Once trained, a technician should be able to retest a patient (changing electrodes) to within a 1% difference in the resistance reading.

• What is the average amount charged for a BIA test?

  $15.00 charge at a health fair and $25.00 to as high as $150.00 for a test done in other environments. The price will depend on the location and the degree of professional consultation.

• How often should the test be performed?

  This would depend on your facility and your client. The average professional generally tests every four to six weeks.

• How could the RJL analyzer be useful in my everyday practice?

  Examples would be a post delivery weight reduction program in an OBGYN setting or lifestyle change in a wellness setting.
