How to Test Blood Glucose

Testing blood glucose levels typically involves using a glucose meter, also known as a blood glucose meter or glucometer. Here is a general step-by-step guide on how to test blood glucose:

Gather the necessary supplies: You will need a glucose meter, test strips, a lancing device, lancets, and alcohol swabs for cleaning the testing site.

Prepare the glucose meter: Ensure that the glucose meter is properly set up with a fresh battery if needed. Follow the manufacturer's instructions for turning on the meter and setting the date and time.

Clean your hands: Wash your hands with soap and warm water, and dry them thoroughly. This step is important to ensure accurate readings and prevent contamination.

Insert a test strip: Insert a fresh test strip into the glucose meter following the manufacturer's instructions. The meter will typically turn on or prompt you to do so after the test strip is inserted.

Prepare the lancing device: Load a lancet into the lancing device according to the manufacturer's instructions. Adjust the depth setting on the lancing device based on your skin's thickness and the device's instructions.

Clean the testing site: Use an alcohol swab to clean the area where you will prick your finger. Allow the area to dry completely before proceeding.

Prick your finger: Use the lancing device to prick the side of your fingertip. Gently squeeze your finger to produce a small drop of blood.
Apply blood to the test strip: Touch the droplet of blood to the designated area on the test strip. The strip will absorb the blood, and the glucose meter will typically display a countdown or processing symbol.

Wait for the result: The glucose meter will process the blood sample, and after a few seconds, it will display your blood glucose level on the screen.

Record the result: Note the blood glucose reading in a logbook, smartphone app, or any other method recommended by your healthcare provider. Keeping a record of your blood glucose readings can help track patterns and assist in diabetes management.

Dispose of the lancet and test strip: Safely dispose of the lancet and used test strip following the proper waste disposal guidelines.

Blood glucose control is required to be performed frequently and accurately, as well as safely, in many clinical situations. This helps diabetics to monitor their glucose levels without having to visit the doctor’s office or hospital, and thus makes stabilization of blood sugar achievable on a larger scale.

In many cases, it is preferable for the testing to be carried out at home, because it is less expensive, less invasive, and safer.

The sides of the finger pads are the most commonly used sites for home or near-patient (point-of-care) testing. This site is ideal, because the center of the finger pad contains an abundant nerve supply, which could make the needlestick more painful.
