Step-by-Step Guide: Performing the Test
Follow these steps carefully to ensure an accurate and reliable blood sugar reading:
Step 1: Wash and Dry Your Hands
- Wash your hands thoroughly with warm water and soap. This removes any food residue or contaminants that could affect the reading.
- Dry your hands completely with a clean towel. Any residual water can dilute the blood sample and alter the result.
Step 2: Prepare the Lancet Device
- Insert a new lancet into the lancet device, following the manufacturer's instructions.
- Adjust the depth setting on the device. Start with the shallowest setting and adjust as needed until you get a sufficient blood sample.
- Cock the device to prepare it for use.
Step 3: Prepare the Blood Glucose Meter and Test Strip
- Turn on your blood glucose meter.
- Insert a test strip into the meter, following the instructions provided with your device. The meter will usually display a symbol indicating it's ready to receive a blood sample.
Step 4: Select and Clean the Puncture Site
- Choose a puncture site on the side of your fingertip. Using the sides reduces pain compared to the center of the fingertip.
- Clean the chosen site with an alcohol swab and allow it to air dry completely. This step is crucial to prevent infection and ensure an accurate reading.
Step 5: Prick Your Finger
- Hold the lancet device firmly against the cleaned puncture site.
- Press the release button to prick your finger.
- Gently massage or squeeze your finger near the puncture site to encourage a blood drop to form. Avoid squeezing too hard, as this can dilute the sample with tissue fluid.
Step 6: Apply the Blood Sample to the Test Strip
- Hold the test strip to the drop of blood, allowing the meter to draw the blood onto the strip. Make sure the blood fills the sample area completely, as indicated by the meter instructions.
- If the blood drop is too small, do not squeeze excessively. Instead, gently massage your finger again or use a new lancet to obtain a fresh sample.
Step 7: Wait for the Result
- Wait for the blood glucose meter to process the sample and display the result. This usually takes a few seconds.
- Record the result in a blood sugar logbook or a digital tracking app, along with the date, time, and any relevant information, such as meals consumed or physical activity undertaken.
Step 8: Dispose of the Lancet and Test Strip Safely
- Carefully dispose of the used lancet in a sharps container to prevent accidental needle sticks and the spread of infection.
- Remove the used test strip from the meter and dispose of it properly.
- Clean the blood glucose meter according to the manufacturer's instructions.
Step 9: Stop the Bleeding
- Apply a clean cotton ball or gauze pad to the puncture site.
- Apply gentle pressure until the bleeding stops.
