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.
 Glucose Testing Meter
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

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.
 Examples
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:
1. Can be painful
2. Messy
3. Costly
4. Average number of tests a day
is 1.6, compared to the
recommend 4 times a day
Non-Invasive Glucometer
(Future)
•
How it works:
1. Finger or Earlobe goes into the
slot
2. Uses near-infrared light to
measure real-time blood
glucose levels
3. Takes 20 seconds or less
•
What Separates This Device From
 Other Non-Invasive Devices?
1. “Optical Bridge”
2. 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.

Grove’s 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
