Glucose Testing

• Glucose Testing is a important and vital part of
  a diabetics daily health care.
• Without testing, a diabetic can become sick
  because their glucose levels are not where they
  need to be.
• Glucose testing is done by using a glucose
  testing meter, which uses a glucose testing strip.

Steps for Testing Glucose

• To test for glucose one must drop a sample of
  blood by placing on the strip.
• This is done by poking the skin with a needle
  called a lancet.
• The lancet pricks the finger which allows the
  sample of blood to flow right onto the glucose
  strip.
• Once the blood sample has made it on to the
  glucose strip, a device called a glucose meter is
  used to measure the glucose in the blood. In each
  test strip, there is a chemical called glucose
  oxidase.
• This glucose oxidase reacts with the glucose in
  the blood sample and is created into a acid
  called gluconic acid.
• This current is then able to read and determine
  how much glucose is in the sample of blood on the
  testing strip. The number is then relayed on the
  screen of the glucose testing meter.

Blood Glucose Meters

• Examples

• A glucose meter is used to determine the
  approximate concentration of glucose in the
  blood.
• The glucose meter is a key element in monitoring
  diabetes can help test if the blood sugar is too
  high or low.
• Glucose meters are small and are handheld, they
  can fit in the palm of a hand.
• Glucose meters cost anywhere from 20 to the most
  advanced meters costing 500.

One Touch Verio Glucose Meter System

• The One Touch Verio glucose meter is practical,
  reliable, and affordable.
• This glucose meter provides instant notifications
  of high and low blood sugar trends, unsurpassed
  accuracy, and requires a very small blood sample
  size.
• The Verio glucose meter is one of the more recent
  and efficient meters that have came out in the
  past couple years.

• Specialized Glucose Meter

Invasive Glucometer (Current)

• Present day best way blood sugar level
• The reason is accuracy
• Problems
• Can be painful
• Messy
• Costly
• Average number of tests a day is 1.6, compared to
  the recommend 4 times a day

7
Non-Invasive Glucometer (Future)

• How it works
• Finger or Earlobe goes into the slot
• Uses near-infrared light to measure real-time
  blood glucose levels
• Takes 20 seconds or less
• What Separates This Device From
• Other Non-Invasive Devices?
• Optical Bridge
• Measurements are taken directly from the blood
  not from interstitial fluid

Conclusion

• Glucose meters are mostly accurate but biomedical
  engineers are constantly finding new problems
  with them which they are using to help to make
  the next glucose meter more innovative and
  useful.
• The future for Glucose Meters is providing a
  device with precise accuracy, easy to use,
  affordable, and new software to detect any
  problems a diabetic may be having.
• Groves Future Device
• Passed International Standard for the last 2
  years
• Expected to be released during 2013 summer
• Faster, cleaner, and pain free compared to
  invasive devises
• Small and battery operated
