Diabetes Monitoring Systems for Diabetics

Tracking the level of glucose in the blood is vital for proper diabetes management. Fortunately, the devices available to do that today are easy to use and provide many features.

One of the earliest self-test systems was developed in the mid-1970s. Then as now they used a sample of blood that is chemically analyzed by the device. Since then, they've gotten smaller, more accurate and require less blood.

Diabetes Monitoring Systems, such as diabetic monitors now extrude a tiny test strip coated with chemicals used to perform the procedure. A small blood sample is provided, usually by pricking the finger with a lancet. The blood drop is smeared on the strip, then fed into a hand-held device. In a few seconds, it provides a readout of the current blood glucose level of the diabetic.

There are several pros and cons to all current diabetes monitoring systems.

It's important to realise too that they can give inaccurate readings if they're not calibrated and maintained properly. Also worth noting is that diabetes monitoring system will need to be cleaned from time to time, in order to prevent old blood and chemicals from cross-contaminating the device and throwing out the readings. But that's generally simple to do, and the results are typically as accurate as a professional test from the laboratory.

Many contemporary diabetes monitoring devices far exceed the features available from their older cousins.

While having the convenience and timeliness of a home test is a great benefit, there are other desirable attributes for a good monitor. Many that are available today will store many test results taken over time.  This will help compare blood sugar levels on an ongoing basis, thus providing better glucose level management for the diabetic. It's even possible with some diabetes monitors to download the results to a PC where the data can be easily graphed, making the tracking process even more valuable to the diabetic.

Several models allow the user to draw blood from areas other than the finger. That gives the fingers a rest, since continual pricking can lead to excessive scarring and loss of sensitivity. It can also lead to running out of fingers to use and greater difficulty drawing blood, leading to additional discomfort. Alternative devices, if approved for use by your physician, can draw blood from the hands, arms and elsewhere.

But there are even better devices available on the market today.

Some use a laser to make a small, painless hole in the skin. A droplet of blood oozes out for smearing onto a test strip. It produces only a slight tingling sensation in the finger during the test. That eliminates the need for needles and is more sanitary and safer, as well as reducing discomfort.

Some work even while you sleep. No one wants to wake up in the middle of the night to prick a finger and run a test strip through the device for a readout. But the body continues to function twenty-four hours a day. Glucose levels can rise or fall at any time. Diabetics can buy a watch that monitors glucose level and alerts the wearer by an alarm if a threshold is exceeded.

Still more advanced devices require drawing no blood at all. It senses the blood glucose level through the skin by use of an infrared beam. In had been in development since the mid ninety's and was recently approved by the FDA for home use.
