Step-by-Step Guide to Performing the Blood Sugar Test

Now that you have gathered your supplies and prepared your testing environment, follow these steps to perform the blood sugar test accurately.

Detailed Testing Steps

Clean the Puncture Site: Use an alcohol swab to clean the side of your fingertip (usually the ring or middle finger). Allow the alcohol to dry completely before proceeding to avoid stinging and potentially affecting the result.
Prick Your Finger: Hold the lancing device firmly against the cleaned area of your fingertip. Press the release button to prick your finger.
Milk Your Finger (Gently): Gently massage or "milk" your finger near the puncture site to encourage a drop of blood to form. Avoid squeezing too hard, as this can introduce tissue fluid and dilute the sample, leading to inaccurate results.
Apply the Blood to the Test Strip: Hold the edge of the test strip to the drop of blood until the meter indicates that enough blood has been applied. Be sure to follow the specific instructions for your meter; some require you to apply the blood to the top of the strip, while others require it on the side.
Wait for the Reading: The blood glucose meter will display your blood sugar level after a few seconds. Record the reading in a logbook or digital tracking app to monitor trends over time.
Stop the Bleeding: Apply a clean cotton ball or gauze to the puncture site and apply gentle pressure until the bleeding stops. This usually takes only a few seconds.
Dispose of the Lancet: Safely dispose of the used lancet in a sharps container to prevent accidental needle sticks and contamination.
