The test result comes out too high or too low.

Please check whether the code number on the strip bottle is the same as the number on the screen. Use the meter at a room temperature of 10~40℃ after 30 minutes. If the strip is out of the bottle for a long time, it might affect to the test result.

Make sure that the bottle cap is closed tightly. If you still get incorrect test results even after following all the instructions, please consult a healthcare professional.
