Proposed System Operation |
| |
|
|
The following brief video is intended to provide a demonstration of the basic steps in performing a test - inserting sensors, adding test solution to the sensors, and test processing/results. |
| |
|
|
The system is expected to operate using consumables packaged in kits with material to perform 192 tests. Each kit will include: - Disposable sensors (192) - Reagent tubes (192) - 2 levels of control material (Level 1: 7 μg/dL; Level 2: 25 μg/dL) - An electronic calibration button, calibration will take less than 5 seconds. Please respond to the following statements about the proposed system operation.
