Hi friends!!!
In our previous blog, we have discussed about cochlear implants. Please check out for the link given below.
In today's blog we are going to discuss about glucometer.
Monitoring Blood glucose level has become a routine in a diabetic patients life. And glucometer plays a vital role in doing so. Therefore it is important for every common people and healthcare professionals to know about glucometer.
Let's get into the topic.
WHAT IS
GLUCOMETER?
The glucometer is used to identify the level of glucose in the blood. The glucometer is a hand
held device that tells whether blood glucose level is high, low or right on the
target value. The glucometer uses test strips to measure blood glucose level.

WHAT IS THE NEED TO
MEASURE BLOOD GLUCOSE
LEVEL?
Maintaining
optimum level of glucose in blood is a job of pancreas in our body. Pancreas
secrete glucagon and insulin, it also maintains them at a value of
approximately 100 ,milligrams per deciliter of blood. If our pancreas does not
able to fulfill its function, our body will not be able to secrete insulin and
maintain optimum blood glucose level. So it is important to manually check blood glucose levels periodically and
inject ourselves with insulin to maintain blood glucose level.
WHAT IS THE
TECHNOLOGY OF
GLUCOMETER?
The glucometer works based on electrochemical technology. The test strips of glucometer consists of an enzyme called glucose oxidase. Glucose oxidase reacts with glucose in the blood droplets applied on the test strips and forms gluconic acid. There is a another chemical in the test strip called ferricyanide. These gluconic acid reacts with ferricyanide to form ferrocyanide. Now glucometer passes electric current onto the test strips.The electric current reads the ferrocyanide and determine the blood glucose level.
GLUCOMETERS?
INVASIVE OR SELF MONITORING
GLUCOMETER
Invasive glucometer is the most common types of glucometers used as home based glucometer. It uses test strips
with blood droplets to measure blood glucose level.

ADVANTAGES
1. Invasive glucometer is portable, cheap cost of device and easy to use.
DISADVANTAGE
1. Additional cost
of buying test strips frequently.
2. Pain during finger pricks.
NON INVASIVE GLUCOMETR
The non invasive glucometer measure blood glucose levels without the use of blood droplets. The non invasive glucometer is sensor based and measures glucose levels on the blood rich areas of the
skin. Now a days sweat based blood glucose monitors are available.
ADVANTAGES
1. No additional cost
of buying test strips.
2. No pain during
finger pricks.
DISADVANTAGES
1. External factors
may affect sensor reading.
CONTINUOUS GLUCOSE MONITORS
In continuous
glucose monitors, a sensor is implanted under the abdominal skin to measure
glucose readings 24 hours a day. To ensure the accuracy of the sensor, we still
need to do finger prick tests daily with invasive glucometer. They are used to
measure glucose levels during various routine activities of diabetic patients life.
Example: During exercising, sleeping, playing etc.
ADVANTAGE
1. This type of glucometer can take time based readings.
2. We can get
better interpretation of glucose levels.
DISADVANTAGE
1. It needs minimally
invasive surgery to implant the sensor under the skin.
WHAT ARE THE FEATURES
TO LOOK OUT IN
GLUCOMETER?
1. Availability of
mobile app to store test results and track previous results.
2. Bluetooth connectivity to have bluetooth glucose meter to share the test data.
3. No coding
facility to use new batch of test strips without calibrating the code.

WHAT ARE THE
COMPANIES
MANUFACTURING
GLUCOMETER?
1. Pulsatom
Healthcare – India’s first indigenous glucometer in 1995.
2. Bhat Bio-Tech
India (P) Limited, Bangalore.
3. OK Biotech Co.,
Ltd, Taiwan.
Now I hope you have acquired some knowledge about glucometer. We will discuss in detail about a topic related to Biomedical Engineering in our next blog.
NOTE: Dear friends!!! ...Please do comment a topic related to Biomedical, so that we can discuss it in future blogs.
