2. Product Overview
On Call Express Blood Glucose Test Strips are designed for quantitative measurement of glucose in fresh capillary whole blood samples. These strips are intended for in vitro diagnostic use only (for self-testing outside the body) by people with diabetes at home and by healthcare professionals in clinical settings as an aid in monitoring the effectiveness of diabetes control.
The test strips feature no-coding technology, requiring a small blood sample (0.4 µL) and providing results in approximately 4-5 seconds. They are compatible exclusively with On Call family blood glucose meters.
