Incorrect operation when using a glucometer can lead to test failure or inaccurate results. The operating procedures for various glucometers are similar. Patients must read the instructions carefully before testing and correctly master the operation method of the glucometer.
Common incorrect operations include: ① The test strip is not fully inserted into the bottom of the test hole during testing. ② Some devices require you to drop blood first, then insert the test strip into the glucometer. If the time waiting after dropping blood exceeds two minutes before inserting the test strip into the test hole, it will result in inaccurate test results. In this case, a new test strip should be used for retesting. ③ Situations such as the test strip moving during testing will also affect the test results. Therefore, the glucometer should be placed in a stable and safe location for use.
