TEST LIMITATIONS
Normal endogenous (within body) natural levels of uric acid, ascorbate (vitamin
C),
bilirubin, triglycerides, and hemoglobin do not interfere with your blood glucose
results. Elevated levels of these compounds in your blood may, however, interfere
with the accuracy of your blood glucose results obtained with the Dario™ System.
The system should not be used if blood levels of these compounds exceed the
limitations detailed in the table below.
Compound
Limitation
Ascorbic acid
> 4 mg/dL
Uric acid
> 5 mg/ dL
Acetaminophen
> 6 mg/dL
Total bilirubin
> 35 mg/dL
Triglycerides
> 810 mg/ dL
The drugs L-dopa, dopamine, methyl-dopa, acetaminophen, and ibuprofen will
not
interfere with Dario™ system blood glucose results when taken at therapeutic
concentrations.
Patients undergoing oxygen therapy may yield false results.
PERFORMANCE ANALYSIS
Dario™ BGMS was tested on 600 samples using capillary blood samples and three
Dario™ test strips lots. Results were compared to YSI ® analyzer. The table below
compares the performance of the two methods. Acceptance criteria in ISO15197:2013
are Ninety-five percent (95%) of the measured glucose values shall fall within either
±0.83 mmol/L of the average measured values of the reference measurement
procedure at glucose concentrations < 5.5 mmol/L or within ±15% at glucose
concentrations ≥ 5.5 mmol/L.
