Blood glucose can be tested at home using a handy electronic device named a blood glucose meter with a small blood drop. Also, a device named continuous glucose monitor (CGM) is equipment to check blood sugar levels that can be used for testing.

As per the Centers for Disease Control and Prevention (CDC), normal blood sugar levels range between 70 and 140 mg/dL. Low blood glucose (hypoglycemia) is the condition when glucose levels go below 70 mg/dL, and high blood glucose (hyperglycemia) is when the levels go beyond 140 mg/dL.

  • Prior to meals: 80 to 130 mg/dl
  • 2 hours after a meal: less than 180 mg/dl
  • Prior to bedtime snack: 100 to 150 mg/dl

Performing Test For Diabetes at Home

Blood sugar tests are available in varying forms, but they all serve the same purpose: to give information about what the glucose level is at that time. A lot of home tests require:

  • a glucose meter
  • a lancet (which is a small needle)
  • a lancing or lancet device (which holds the needle)
  • test strips

Some general steps following a home test:

  • Hands must be properly washed.
  • A lancet is then placed into the lancet device.
  • A new test strip is placed into the glucose meter.
  • A finger is then pricked using a lancet.
  • A drop of blood is then put onto the test strip and the results come in the glucose meter.

Results usually come within seconds. In some glucose meters, a person requires to be sure about the code on the strip to get matched with the code on the meter. Also, one must be sure of checking the date mentioned on the strips occasionally to ensure they aren’t outdated.

  • It’s good to discuss with the doctor if and how often a person can check blood sugar at home if the person is not using insulin.
  • Testing can be done before and after meals to examine how diet has an impact on blood glucose. It’s particularly significant to test after consuming simple carbs or sugary foods to ensure that the sugar levels are not too high.
  • Also, it’s very important to test whenever a change is made in the treatment plan or when a person feels sick.
  • A blood sugar chart for keeping track of blood sugar is essential for recording the results. Tracking can be done on paper or electronically. This information can be helpful for a person in determining patterns and potential issues.

Charts should be saved and should be taken to the doctor every time a person visits the doctor. While writing down the test results, also make sure to note:

Home Testing Versus Medical Testing

Can you self-test for diabetes? Self-monitoring the glucose levels is critical for determining the extent of diabetes each day. It’s irrational to believe that some tests every year (at the physician’s office) can deliver a precise interpretation of the medical condition as sugar levels vary all through the day. On the other hand, this also doesn’t indicate that home tests can replace regular preventive testing.

Along with the self-monitoring at home, a physician can advise an A1c home test. This test examines how the sugar levels have been averaging over the last 2-3 months. A1c tests are done up to 4 times per year. Regular laboratory tests are also great for a person in determining how well the diabetes is under control. Also, these tests determine the person, as well as his or her healthcare team, decide how often home tests can be used and what the target reading must be.

  • Better assurance in diabetes care.


Can you measure blood sugar at home? Testing blood glucose is a vital part of a diabetes care plan.

By regularly monitoring the blood sugar levels, a patient can find out problems in the current diabetes care.
