What is Glucose ?
Glucose is a simple sugar that provides the body with its primary source of energy.
This type of sugar comes from digesting
carbohydrates
into a chemical that the body can easily convert to energy. When glucose levels in the bloodstream aren't properly regulated, a person can develop a serious condition, such as
diabetes
.
Slide3
What is Glucose ?
This functional form of energy then gets absorbed through the small intestine into the bloodstream. It is then carried throughout the body, providing energy for the person to perform all types of activities, such as simple movements, demanding physical exercises or even thinking. Slide4
Normal blood sugar ranges
The
normal blood glucose level
in humans is about (4
mmol
/L or 72 mg/
dL
)
The body,
when operating normally
, restores the blood sugar level to a range of about 4.4 to 6.1
mmol
/L (82 to 110 mg/
dL
)
Shortly after eating
the blood glucose level may rise temporarily up to 7.8
mmol
/L (140 mg/
dL
) Slide5
How to measure concentration of glucose in blood
A
glucose meter
(or
glucometer
) is a
medical device
for determining the approximate concentration of
glucose in the blood.Slide6

It is a key element of home
blood glucose monitoring
(HBGM) by people with
diabetesSlide7
Technology
How it works
Most
glucometers
today use an electrochemical method.
Test strips contain a capillary that sucks up a reproducible amount of blood.
The glucose in the blood reacts with an enzyme electrode containing glucose
oxidase
(or
dehydrogenase). The enzyme is reoxidized with an excess of a mediator reagant.Slide8
Technology
The mediator in turn is
reoxidised
by reaction at the
electrode,which
generates an electrical current.
The total charge passing through the electrode is proportional to the amount of glucose in the blood that has reacted with the enzyme.Slide9

Blood glucose monitoring using

A new way to help diabetics record and share critical health information
.
Over 17.9 million Americans have diabetes, and they all live with the painful, often thrice-daily process of using needles to check blood sugar. The process is clunky and uncomfortable -- and dangerous due to potential errors. But a new
iPhone
-compatible
glucometer
hopes to change all that, by improving the blood collection process while providing an easy way to track data.Slide12
Blood glucose monitoring using
iPhone
This new product can actually take blood samples using a device that plugs right into the
iPhone
.
This system replaces less accurate and more cumbersome stand alone
glucometers
that do not store or wirelessly transmit
data.
A small glucometer accurately reads blood sugar from a strip that a very small sample of blood is placed on -- "a prick that can hardly be felt”.Slide13
Easy to carry every where and more portable
A case can be fitted around the meter that wraps around the phone, keeping it extremely handy for users who are on the go. And like a text message from your body,
a
prompt can be programmed into the
phone
to serve
as
a reminder to check levels.Slide14
Software access
Using the
iPhone
app
in conjunction with the monitor also allows the meter to do many things it could not do alone. Namely, the app allows the user to input various
behavioral
or environmental changes -- skipped a meal, exercised, recently injected insulin -- and can track that information along with the blood sugar
levels.Slide15

glucometer
, show how the information is plotted.Slide16
Software access
The data stored in the application can be accessed on the phone or the computer, allowing the user to always have the information at hand for a health care
provider.
The
data can be programmed to be
shared.
