Blood Glucose Monitoring Systems are for self-testing
users to test fresh capillary blood. For over the counter sale. Never test blood that
has been placed in test tubes containing fluoride or other anticoagulants. This
will cause falsely low results.
•
Very high (above 55%) and very low (below 30%) hematocrit levels can cause
false results. Talk to your doctor to find out your hematocrit level.
•
The system is tested to accurately read the measurement of glucose in whole
blood within the range of 20-600 mg/dl.
•
Fatty substances have no major effect on test results. These include
triglycerides up to 3,000 mg/dl or cholesterol up to 500 mg/dl.
•
Ascorbic acid (vitamin C) when occurring in blood at normal or at high
therapeutic concentration does not significantly affect results. However,
abnormally high concentration (> 3 mg/dl) in blood may cause inaccurately high
results.
