New In The Market
UFIT® leverages advanced measurement, computation, and communications technologies to offer an online system that anyone can use to evaluate and manage their health
pressure waves
– Heart beat vibrations sent through the
arterial system are dynamically
captured at the wrist using oscillometric
method
– Glycemia is estimated by analyzing
pulse features attributable to blood
glucose
– Works well where pulse pressure is >30
mmHg
– Thick tissues (arm) distort
transmission/reception, however the
wrist has very thin tissues making it
ideal for capture
UFIT Glucose Estimation Module
UFIT Glucose Estimation Module (GEM) was evaluated against a leading glucometer on 416
participants. The study was conducted according to the relevant international standard (ISO
15197:2003, In vitro diagnostic test systems -- Requirements for blood-glucose monitoring
systems for self-testing in managing diabetes mellitus).
Accuracy
Accuracy for glucose concentrations greater than 4.2 mmol/L was determined to be 95.48 %
within ± 20 % of the mean reference glucose concentration. Repeatability for glucose
concentrations greater than 4.2 mmol/L was determined to be 98.93 % within ± 20 % of the
mean GEM glucose concentration.
Superior measurement performance
The results show a pattern of superior measurement performance of the UFIT® monitor
compared to the Glucometer, both in terms of accuracy and precision.
?????? The UFIT monitor provides an estimated glucose value which closely matches the gold
standard derived from the laboratory analysis of a blood sample.
?????? The modest (approximately 2%) overestimate is quite consistent over the full range of
glucose values examined and likely to be unimportant if the device were being used for
routine monitoring.
?????? The precision of the UFIT device is also very impressive with a consistent SD of about
0.47 mmol/L (coefficient of variation 4%).
?????? Ninety-eight of the 102 patients studied (96%) were observed to have UFIT glucose
within ±1 mmol/L of the lab value and 73 (72%) within ±0.5 mmol/L.
?????? These are very impressive figures for a totally noninvasive device which estimates blood
glucose indirectly by analyzing blood flow pulse waves recorded during the measurement
of blood pressure at the wrist.
