The ELGII predicts lean body mass with reproducible scientific accuracy when compared to the criterion hydrostatic tank

[ELG Sensor sites] [Performing the test]

APPLYING THE ELG SENSORS

  A fresh set of sealed BIO|ANALOGICS' ELG sensors (4 sensors) is required to perform an ELG bioimpedance test.

*Note: Only BIO|ANALOGICS' "Impedance Code A" ELG Sensors are recommended for their low impedance (< 3 ohms) and high conductance values. To insure scientific accuracy and good hygiene practices, new ELG Sensors should be used for each test.

First Sensor Site
  The first sensor should be placed on the back of the right hand near the wrist. Locate the "Styloid Process" (the bump near the back of the wrist). Place the center of the first sensor in the middle of the wrist just across from the Styloid process. The first red alligator clip will be attached here (A).

Second Sensor Site
  The second sensor should be placed on the back of the hand, directly behind the knuckle of the index finger. The first black alligator clip will be attached here (B).

Third Sensor Site
  The third sensor should be placed on top of the ankle, bisecting a line between the Medial and Lateral Malleoli (the bumps located on the inside and outside of the ankle. The second red alligator clip will be attached here (C).

Fourth Sensor Site
  The fourth sensor should be placed directly behind the joint of the great toe. The second black alligator clip will be attached here (D).

PERFORMING A BIOIMPEDANCE TEST

  Once the patient has been properly connected to the ELG meter, their bioimpedance may be accurately measured. The patient should be supine (lying down) on a nonconductive surface such as an exam table or massage table, or standing comfortably with arms and legs slightly spread. The supine position is preferred due to potential fluctuations in readings associated with muscle contraction in the legs while standing.

*Note: A sitting position is never recommended and will yield unpredictable results.

Calibration
  Press the ELGII Calibrate and Operate buttons simultaneously. The LCD screen should read 000 indicating that the meter in calibration.

        

Operation
  Once the ELGII meter calibration has been verified, release the calibrate button and continue to press the Operate button only. In a few seconds, the patient's bioimpedance value will appear on the LCD screen. This number is then recorder for input into the body composition algorithm contained in the HMS Body Composition module or the QuickComp Body Composition Calculator. A typical reading is in the range of 300 to 700 ohms.

You are now ready to produce a body composition report.
