New Generation of Abbott Monitor Sports Extra Features
On June 5, 2004, Abbott Laboratories introduced the new and improved Precision Xtra Advanced Diabetes Management System.
The monitor offers advanced diabetes management capabilities, including:
- Two-step testing
- Three-button design for easier testing and programming
- Backlight for testing in low light
- 450-test memory with seven-, 14- and 30- day averaging results
- TrueMeasure technology test strips for alternate-site testing.
In addition, the Precision Xtra can measure blood ketones using separate ketone test strips, making it the first home monitor to have such a feature.

CGMS Shows Extended Life Beyond Current 72 Hours
The new version of Medtronic MiniMed Continuous Glucose Monitoring System (CGMS) provides “accurate glucose values and trend information without requiring that the user calibrate the device while it is worn,” say Stanford University researchers. In addition, the CGMS allows for daily activities such as showering.
In a study to determine if the CGMS with wireless transceiver can safely extend beyond the current labeling of 72 hours for “active pediatric patients,” 10 children with type 1 wore two CGMS devices simultaneously for seven days. In addition, patients self-monitored blood glucose during the study with the BD Paradigm Link.
According to the researchers, 18 sensors contributed data by the end of the study, resulting in 94 and a half days of experience. CGMS life was 126 hours or approximately five days.
There were 10 and a half hours of gaps in continuous glucose monitoring that did not contribute to data; these were attributed to system events, such as calibration error, sensor out of range and sensor disconnect.

The FreeStyle Navigator Warns of Lows
The FreeStyle Navigator is TheraSense’s continuous glucose monitor, which in a recent study correctly identified 92.4 percent of all low blood glucose events.
The FreeStyle Navigator wireless transmitting system has a tiny electrochemical glucose sensor that is inserted beneath the skin into the interstitial fluid for three days.

Don’t Count on BG ‘Guesstimates’
Kids and Parents off the Mark
School-aged kids with type 1 and their parents exhibit poor overall ability to detect high and low blood glucose (BG) fluctuations. Using handheld computers, 27 children ages 6 to 11 and their parents rated the child’s current symptoms, recent food intake and exercise and then estimated the current BG level prior to measuring it three to four times a day over a one-month period. Across all BG ranges, parents and children made clinically accurate estimates 29 and 23 percent of the time, respectively. Failure to detect low BGs was the most common error. The Virginia and Boston researchers suggest that blood glucose awareness training (BGAT) may be useful for this population.
