Q12. Why do I get different results in successive measurements using
the same meter?
(1) Test strip problems:
A. Test strip expired
B. Test strip contaminated or damaged
C. Not enough blood applied to the test strip
(2) Meter problems:
A. The meter is damaged.
B. Wrong code between test strip and meter
C. Unknown electronic elements defect
(3) The blood sampling surface is not clean, make sure to wash your hands before
doing the test.
(4) Improper blood obtaining:
A. Excessively squeezing your finger can cause too much tissue fluid in the
blood samples and get the wrong measuring value.
B. If you are using a site other than your fingertip and you think the reading is
wrong, test again using blood from a fingertip. Blood samples from alternate
sites are not as accurate as fingertip samples when your blood sugar level is
rising or falling quickly.
(5) Extreme temperatures or humidity:
A. Keep your glucose meter and test strips at proper operating temperature
and humidity based on the Owner’s manual in each meter and strip.
(6) The number of red blood cells in your blood:
A. If you are dehydrated or your red blood cell count is low (anemia), your test
results may be less accurate. Please refer to the Owner’s manual and
consult a doctor to check the suitable hematocrit range for testing.
