When testing blood sugar levels, people often make some oft-repeated mistakes that can lead to inaccurate readings and poor diabetes management. “It is necessary to keep track of blood sugar levels to be able to manage them,” said Dr Manjusha Agarwal, senior consultant, internal medicine, Gleneagles Hospital, Parel, Mumbai.
Testing at the wrong time: Testing immediately after eating can lead to high readings. It’s best to test 2 hours after a meal for accurate results. “Testing at irregular times, such as right after eating without following a consistent routine, can also create confusion and inappropriate results,” said Dr Agarwal.
Pricking the fingertip: The fingertip has more nerve endings, making it painful. Instead, prick the sides of your fingers for less discomfort.
Not changing lancets: Reusing lancets can cause pain and infection. Change lancets regularly to ensure a smooth testing experience.
Using expired or poorly stored test strips: Expired or poorly stored test strips can give inaccurate readings. Always check expiration dates and store strips properly. Using an old or damaged test strip is another issue, as expired strips may give wrong results. Some people don’t store strips properly, exposing them to heat and moisture, and inaccurate results, said Dr Agarwal.
Not washing hands: Failing to wash hands before testing can lead to contaminated readings. Wash your hands with soap and water before testing, said Dr Narander Singla, lead consultant, internal medicine, CK Birla Hospital, Delhi.

Not testing enough: Infrequent testing can lead to poor diabetes management. “Test regularly to track your progress,” said Dr Singla.
Not understanding the glucose meter: According to Dr Singla, not knowing how to use your glucose meter can lead to errors. Read the manual and consult your doctor if needed, he said. Dr Agarwal mentioned that not keeping a proper log of readings is another oversight, making it harder for doctors to give the right advice.
Skipping meals: Skipping meals can increase blood sugar levels. “Eat small, frequent meals to maintain stable levels,” said Dr Singla.
Not rotating test sites: Testing the same finger repeatedly can cause discomfort. “Rotate fingers to avoid pain and callus buildup,” said Dr Singla.
