Glucose monitoring devices

Traditional glucose meters have long been a mainstay in diabetic management. Testing glucose is a major part of the treatment plan for diabetic patients. Glucometers are portable, easy to use, and convenient medical devices, that help to test blood glucose levels anywhere and anytime.

There are many factors that affect blood glucose levels like diet, exercise, stress, illnesses, and medications throughout the day. Self-monitoring allows us to see how these factors affect glucose levels and give us a chance to make modifications for a better control. It also alerts us if glucose levels go too high or low preventing emergency situations.

Glucometers come with glucose testing strips, lancets, and a lancing device. There are a variety of glucometers on the market, that comes with different features to suit everyone’s requirements, for example:

  • Monitors with a large display or audio capabilities for patients with vision problems.
  • Backlit screen to allow you to see in dim light.
  • Additional memory or data storage.
  • Bluetooth-enabled devices that sync with your smartphones and automatically log the test results in a dedicated app and store them.
  • USB port to download data directly into a computer.
  • Monitors that allow alternate site testing that gives accurate reading even with a small sample of blood.

The traditional site for taking blood samples are fingertips. Fingertips are rich in blood vessels, so it’s easy to take out a drop of blood however, with time the fingers can become sore with frequent glucose testing. Some glucometers allow taking a blood sample from other sites too such as the palms, upper forearms, legs, thighs, or abdomen. These glucometers give accurate readings even with a small amount of blood. In emergency situations or in case of doubts in blood sugar readings, it is recommended to take samples from the fingertips.

Importance of monitoring glucose

It is important to keep glucose levels in the target range as best as possible.

The general guideline is pre meal targets of 80-130 mg/dL (4.4-7.2) and after meal target less than 180 mg /dl (10mmol/L ) and HbA1c less than 7 %.

Uncontrolled blood sugar can lead to many long-term complications like heart and kidney diseases and vision problems. Very low blood sugar (hypoglycemia) can lead to seizures and coma.

The guidelines differ for different patients. Doctors will recommend the target range and frequency of blood testing. The goals may be adjusted for a patient in whom the strict glucose control may be inadvisable, such as the elderly, patients who experience repeated bouts of hypoglycemia, especially patients with hypoglycemic unawareness, young children, or patients with dementia.


Method of testing blood glucose by finger stick method

  • Wash your hands with soap and water and dry them. Do not use alcohol swabs.
  • Insert a Lancet in the Lancing device and adjust the depth of pricking.
  • Place a test strip in the glucometer. A message will appear on the screen to put a drop of blood.
  • Massage the fingertip a little to increase circulation, and prick the side of the fingertip with a lancing device. (Pricking on the sides causes less pain)
  • Bring it closer to the testing area on the test strip and lightly touch it. A thin layer of blood will spread evenly and, cover the testing area immediately.
  • Glucometers will analyze the sample and show glucose levels within a few seconds.
  • Press the finger-pricked site for a few seconds with clean tissue paper or gauze to stop the blood from oozing out.

Tips for good blood glucose monitoring

  • Keep monitor and supplies with you all the time in a storage bag or box.
  • Keep track of test strips. Make sure they are not expired, as using expired test strips is not guaranteed to give accurate results.
  • Establish a routine for how often tests are to be done.
  • Record blood glucose test results in a journal or use an app that tracks blood-glucose daily readings.
