The On Call\u00ae Extra Test Strips are thin strips. The strips have a chemical reagent system. They work with the On Call\u00ae Extra family of Blood Glucose Meter. Together, they measure the glucose concentration in whole blood. Blood is applied to the end tip of the test strip. Then the blood is automatically absorbed into the reaction cell. This is where the reaction takes place. A transient electrical current is formed during the reaction. The blood glucose concentration is calculated based on the electrical current detected by the meter. The result is shown on the meter display.
\nThe meters are calibrated to show plasma equivalent results.
\nFor in vitro diagnostic use. Test strips can be used only outside the body for testing purposes. For self-testing and professional use. They are used to measure the amount of glucose in fresh capillary whole blood. Capillary whole blood can be from the finger, forearm, and palm. The system is also used to monitor how well the diabetes control programs work.<\/p>\n","protected":false},"excerpt":{"rendered":"
