Gather Your Supplies: Ensure all your equipment is within reach. This includes your meter, test strips, lancet device, lancets, alcohol swabs, cotton balls, and sharps container.
Check the Expiration Date: Verify that your test strips are not expired. Expired strips can provide inaccurate results.

2. Setting Up the Lancet Device:

Insert a New Lancet: Open the lancet device and insert a new, sterile lancet. Follow the instructions provided with your lancet device.
Adjust the Depth Setting: Most lancet devices have adjustable depth settings. Start with the lowest setting and increase as needed until you get a sufficient blood drop.

3. Preparing the Test Strip:

Insert the Test Strip: Insert the test strip into the blood glucose meter. The meter should turn on automatically. Ensure the code on the test strip matches the code on the meter (if required).

4. Pricking Your Finger:

Choose a Finger: Select a finger to prick. The sides of your fingertips are generally less sensitive. Rotate fingers each time to avoid soreness.
Clean the Prick Site: Use an alcohol swab to clean the chosen area on your fingertip. Allow the alcohol to dry completely before pricking.
Prick Your Finger: Place the lancet device firmly against the side of your fingertip and press the release button.
Milk Your Finger: Gently squeeze or massage your finger near the prick site to encourage a small drop of blood to form. Avoid excessive squeezing, which can dilute the blood with tissue fluid.

5. Applying Blood to the Test Strip:

Apply Blood Sample: Hold the edge of the test strip to the blood drop. The strip will draw the blood in via capillary action. Ensure the blood fills the designated area on the strip.
Avoid Smearing: Do not smear the blood onto the test strip, as this can affect the accuracy of the reading.

6. Reading the Results:

Wait for the Result: The blood glucose meter will display your blood sugar level within a few seconds.
Record Your Result: Write down your blood sugar reading, along with the date and time. Note any factors that may have influenced the result, such as recent meals, exercise, or stress.

7. After the Test:

Stop the Bleeding: Use a cotton ball or gauze to apply pressure to the prick site until the bleeding stops.
Dispose of the Lancet and Test Strip: Immediately dispose of the used lancet and test strip in a sharps container.
Clean Your Meter: Clean your blood glucose meter regularly according to the manufacturer’s instructions.
