Blood-glucose monitors help diabetics to keep track of their glucose levels wherever and whenever they want. The results allow them to make appropriate medical and lifestyle choices, also it is helpful to avoid hyperglycemia and hypoglycemia episodes.
Glucose monitor overview
Glucose monitor is useful to measure the blood glucose level, which in-turn helps better diabetes management. Monitoring of the blood-sugar level allow them to make appropriate medical and lifestyle choices, also it is helpful to avoid hyperglycemia and hypoglycemia episodes.
Other names for glucose monitor are blood-glucose monitor, glucometer, glucose meters, glucose monitors, diabetes monitor, diabetic meter, blood-glucose monitoring system, home glucose monitor.
The most common way to check glucose levels involves pricking a fingertip with an automatic lancet (lancing device - Lancet is a small instrument for pricking the skin with a quick-action fine needle.) to obtain a blood sample and placed on a disposable test strip then using a glucose meter to measure the blood sample’s glucose level.
How do you choose a Glucose monitor?
Important features to consider when selecting a glucose meter: choose a meter,
- Which is conveniently smaller, lightweight, and easy to carry with you?
- That requires a smaller blood sample means less pain.
- Testing speed - gives the result within seconds,
- Option to store test results such as date and time of the test. This helps to keep the record for doctor’s review.
- Other important features you can look for are no coding, high and low blood-glucose level warning, etc.
- Meter & Test strips cost
Glucose Monitor usage procedure
The following is the general instructions for usage of a glucose meter:
- First, set out your glucometer, a test strip, a lancet and alcohol prep pad.
- Wash your hands to prevent infection. Decide where you are going to obtain the blood from, usually a finger. Some of the newer monitors let you use your forearm or another less sensitive place.
- Turn on the glucose meter and place a test strip in the machine when the machine is ready. If coding is required, then enter it. Watch the indicator for placing the blood to the strip.
- Make sure your hand is dry and wipe the area you have selected with an alcohol pad and wait until the alcohol evaporates.
- Pierce your fingertip on the soft, fleshy pad and obtain a drop of blood. Place the drop of blood on or at the side of the strip.
- The glucose monitor will take a few moments to calculate the blood-sugar reading.
- You may use the alcohol pad to blot the site where you drew the blood if it is still bleeding.
Glucose meters and the strips, both have instructions for use, read carefully these instructions for proper use and accurate reading.
Glucose monitor - Cleaning & maintenance
Every monitor needs to be taken care of in order to function properly. Some need more cleaning and maintenance than others do and this may be another factor to consider in choosing a monitor. Be sure to follow the manufacturer’s instructions regarding proper care of your monitor. This is important because a monitor may provide inaccurate readings if it is dirty, old, or stored at extreme temperatures.
Non-coded & Plasma glucose monitors
Confirm the glucose monitor is non-coded (now a day’s all the monitors available are non-coded still confirm) and confirm the readings are in plasma glucose (some glucose monitor gives blood-glucose value instead of plasma glucose).
Glucose levels in plasma (one of the components of blood) are generally 10%–15% higher than glucose measurements in whole blood (and even more after eating).
