Record the Result: Record the blood sugar reading in your logbook or app, along with the date, time, and any relevant notes (e.g., food intake, exercise, medication).
Dispose of the Lancet and Test Strip: Safely dispose of the used lancet in a sharps container. Dispose of the used test strip according to local regulations.
Apply Pressure to the Puncture Site: Apply a cotton ball or gauze to the puncture site to stop the bleeding.

Understanding Your Blood Sugar Readings

Blood sugar readings are measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). The target blood sugar range varies depending on individual factors such as age, health status, and medication. However, general guidelines are provided below. Always consult your healthcare provider for personalized blood sugar targets.

General Blood Sugar Targets for Adults with Diabetes (American Diabetes Association Guidelines)

| Measurement | Target Range (mg/dL) | |----------------------|-----------------------| | Before Meals (Fasting) | 80-130 | | 1-2 Hours After Meals | Less than 180 |

General Blood Sugar Targets for Non-Diabetics

| Measurement | Target Range (mg/dL) | |----------------------|-----------------------| | Before Meals (Fasting) | 70-100 | | 1-2 Hours After Meals | Less than 140 |

Important Note: These are just general guidelines. Work with your healthcare provider to determine the appropriate blood sugar targets for you.
