TRUEtrack Blood Glucose Test Strips are very easy to handle (98% of patients rated the testing procedure with TRUEtrack strips "easy" or "very easy") and require only a one microliter blood sample to provide fast, accurate results; their capillary action quickly and easily draws the blood sample onto the blood glucose test strip, and the meter's audible fill detection signals that enough blood has been drawn. Plus, they have proven clinical accuracy and are now more affordable than several other brands.
