II. Indications

  1. Adjunct to Glucometer in Diabetes Mellitus
  2. Medical Letter does not recommend for routine use yet

III. Mechanism

  1. Meter ($300) worn as wristwatch
  2. Samples Glucose levels through intact skin
  3. Disposable auto-sensor snaps onto back of device
    1. Auto-sensor ($4) provides 12 hours of readings
    2. Contains Glucose oxidase gel discs and electrodes
    3. Samples Glucose via reverse Iontophoresis
      1. Low electric current assists Glucose collection
      2. Discs convert Glucose to hydrogen peroxide
      3. Sensor detects electrons released

IV. Technique

  1. Attach auto-sensor to watch
  2. Allow 3-hour warm-up period
  3. Calibrate device with Glucometer
  4. Set high and low alert values
  5. Device displays new reading every 20 minutes
    1. Readings are averages of two ten-minute measurements
  6. Alarm sounds for Glucose values in alert range

V. Efficacy

  1. Accurate for Blood Sugars over 80 mg/dl
  2. Less accurate for Blood Sugars below 80 mg/dl
  3. Accuracy and device function altered by
    1. Perspiration
    2. Device jarring

VI. Adverse Effects

  1. Skin irritation occurs with short-term use
