Blood Sugar Checks

Mother is checking her daughters' diabetes by monitoring blood glucose.
Blood sugar checks are procedures sometimes recommended by medical practitioners in order to measure the glucose levels in your blood. High or low blood sugar levels can lead to symptoms of illness and sometimes even serious complications. Diabetic patients can use this test to help maintain their blood sugar levels during treatment. Blood sugar checks can also be done as part of a routine checkup.

Blood sugar checks are designed to:

  • Determine whether blood sugar levels are high or low
  • Diagnose diabetes
  • Monitor a medication’s effects on blood sugar levels
  • Track whether treatments for blood sugar levels are effective
  • Help determine how exercise and diet influence blood sugar levels in an individual
  • Look for signs of illness or stress


Two methods are used to check blood sugar levels:

  • “Finger prick” test where a small sample of blood is taken from a fingertip and then analyzed by a small machine called a glucometer.
  • Laboratory test where blood is drawn from a vein and then sent to a lab for analysis.

Blood sugar tests can be used to diagnose diabetes, hypoglycemia (low blood sugar) and more. Medical providers may also order fasting blood sugar tests, or a test called a hemoglobin A1C  Fasting blood sugar tests help ensure that recent food ingestion is not impacting results.  Hemoglobin A1C tests are used to evaluate average blood sugar levels over the past 90 days.

When to check blood sugar levels?

Your medical provider will come up with a plan to determine the need for blood glucose testing as well as how often it needs to be performed. A type 1 diabetic may need to check blood sugar more frequently than a type 2 diabetic, for example. Sometimes “spot checks” are done if a person is having symptoms of hyper or hypoglycemia.


Most commonly a blood sugar meter, called a glucometer, is used to check blood glucose levels.  The glucometer measures blood sugar amount using a very small blood sample. This sample is obtained by getting a drop of blood from a fingertip. This drop of blood is then placed on a disposable test strip, which is analyzed by the glucometer. The procedure works as follows:

  • Before the test, wash hands to get the most accurate results.
  • Prick the fingertip with the help of the lancet provided with the test kit.
  • Touch the pricked finger edge with a test strip so that blood can be put on it.
  • Insert the disposable strip into the glucometer.

The measurements of blood sugar levels will be taken immediately on the meter and will be displayed on the screen.

CGM (Continuous Glucose Monitor)

People with type 1 diabetes may use a continuous glucose monitor (CGM.)  With a CGM, a sensor is used to measure blood sugar levels every few minutes. CGMs are used with mobile applications that show glucose data including averages over time. Some devices give alarms on smartphone apps if glucose levels go up or down too quickly. Research has shown that patients with Type 1 diabetes have better blood glucose control when they use a CGM.
