automatically store results, time, and date. The Accu-Chek Complete system
records blood sugar, insulin, carbohydrates, exercise, stress, ketones, HbA1c,
and much more. The Accu-Chek Complete system features “ATM-like” push-
button selection and displays reports in chart or graph form without the need
of a computer.

The One Touch FastTake Blood
Glucose Monitoring System consists of three main products: the FastTake
Blood Glucose Meter, FastTake Test Strips, and FastTake Control Solution.
These products have been designed, tested, and proven to work together as
a system to produce accurate blood glucose test results. The FastTake Me-
ter displays results between 20 and 600 mg/dl (1.1-33.3 mmol/l). If the test
result is lower than 20 mg/dL (1.1 mmol/l), “lo” will appear on the meter
display. This indicates severe hypoglycemia (low blood glucose). Users should
immediately treat hypoglycemia as recommended by their healthcare profes-
sional. If your blood glucose test result is above 600 mg/dl (33.3 mmol/l), “hi”
will appear on the meter display. This indicates severe hyperglycemia (high
blood glucose). Users should seek immediate medical assistance. When the
blood glucose test result is between 240 and 600 mg/dl (13.3-33.3 mmol/l),
“ketones” will appear on the meter display. This message does not mean that
the system has detected ketones, but that testing with a ketone test strip
may be advisable. The characteristics are described below: very small blood
sample size, 1.5
l; patients can use a finer-tip lancet, which means less pain;
accurate results in just 15 s; plasma calibrated for easier lab comparison;
150-test memory with date, time, and automatic 14-day averaging; small,
portable, and easy to use. With One Touch FastTake Test Strips, patients
can test on their arm or fingertips. It is entirely up to them. The arm has
fewer nerve endings, so testing there feels much better; the FastDraw design
automatically pulls blood into the test strip, so patients no longer have to
target blood onto the top of the test strip.

Conclusion
Blood glucose sensors are now commercially available. However, there are
still some problems, namely, the commercially available glucose sensors are
limited to disposable use. Reducing compounds affect the sensor response,
and an accurate blood glucose level cannot be determined. Therefore, further
improvements of the blood glucose sensors should be necessary.
Except for the glucose sensor, most biosensors have not been used. This is
due to the low stability of enzymes except for glucose oxidase. Novel molecular
recognition materials are now being developed. Biosensor development in the
21st century will be drastically different.
