How to Test Your Blood Sugar at HomeWhen you manage your diabetes at home, it leaves no chances for guessing in your regular care. As you know your blood sugar level as soon as you test, it makes for ease in monitoring. Just learn how to test your blood sugar at home and get started with home monitoring of your diabetes.

Get a standard blood sugar testing device and follow these steps to test your blood sugar:

  • Use warm, lathered water to wash your hands. Dry them with a freshly washed towel.
  • Place a needle in the lancet device. Set the device in a way that it pinches just enough to extract a drop of blood from your finger.
  • Take out a test strip from its bottle. Immediately close the lid of the bottle in order to prevent the moisture from causing any damage to the other testing strips.
  • Now, keep your blood sugar meter in readiness after reading the instructions on the label.
  • Keep a piece of clean cotton ready and prick your fingertip with the lancet. See whether your device can be used at other body parts or not, as mentioned in the instructions.
  • Having extracted the blood, make sure that it is placed on the correct spot on the test strip, covering the testing area well.
  • Use the cotton to stop any more blood from coming out by applying pressure.
  • Wait to get the results. It would take only a few seconds with most meters.

Newer meters let you test from body sites other than the fingertip. These alternative testing sites can be forearm, upper arm, base of thumb and thigh. However, testing at these sites may give results different from the level of blood sugar measured at the fingertip. Blood sugar levels are more sensitive to change at the fingertips and can change quicker than the same at the alternative testing sites.

In 1998, a relatively pain-free laser to extract blood was approved by the USA's FDA (Food and Drug Administration). This laser device produces an exact beam of light to penetrate the skin on the finger rather than pricking it. This helps to reduce pain and provide comfort.

Continuous Glucose Monitoring System has also been developed. It uses a device tht has a plastic catheter (very small tube) of small size. It is inserted just beneath the skin. It collects small amounts of fluid and evaluates the sugar content over a period of 72 hours. In 2001, the FDA also approved a watch-like device for diabetes management. It helps people to measure their blood sugar by using electric currents.
