Glucometer
is a portable device with which one can measure and monitor blood sugar levels/
concentration of glucose in blood. Glucometer is of great use to diabetic patients as they can keep a record of their blood sugar levels from the comfort
of their home. This device is easy to use. It helps in providing instant
results regarding the blood sugar levels hence enabling the patient to decide
when he needs to meet his doctor.
Regular monitoring of blood glucose is
important as it can prevent or delay complications of diabetes. Monitoring of
blood sugar level further helps in comprehending the effects of various food
substances and activities on blood glucose levels in your body.
There are different types of glucometers available in the market but
they all perform the same function. Commonly used glucometer kit includes
lancets (needles used to prick the skin); test strips (used to test and measure
blood glucose levels). Each strip is to be used once and then discarded.
Before testing ensure that the test strips have not expired.
LCD display on the glucometer
displays the blood sugar readings and towards the bottom, there is a slot to
fit the test strip. The device has an in-built memory to store the glucose readings. Some models of glucometer can be connected to a personal computer and
the test results can be stored.
Working
Lancet is used to prick the skin
and a small sample of blood is placed on a test strip which is then placed in
the device slot. The sensor underneath this slot transmits the reading for the
blood sample. Test strips are coated with chemicals which react with glucose present
in blood. Glucometer measures the amount of glucose present. Glucose level displayed
is measured in milligrams per deciliter (mg/dL) or millimol per liter (mmol/L).
Volume of blood sample required for testing varies from
model to model, from 0.3 to 1 μl. Time
taken to read the test strip may vary from 3 to 60 seconds for different
models.
Accuracy
Glucometers must meet the accuracy standards set by the International Organization for Standardization (ISO). There are several factors that affect the accuracy of a test, such as calibration of meter, amount and quality of blood sample, cleanliness of meter, humidity, aging of test strips, etc. Good machines too, have a margin of error of minimum 10%. Laboratory testing for blood sugar is advisable once in 6 months.
