Step-by-Step Guide to Using a Blood Sugar Monitor
Using a blood sugar monitor is a relatively simple process, but it's crucial to follow the instructions carefully to ensure accurate readings and prevent infection. Here’s a step-by-step guide:
-
Gather Your Supplies:
- Blood glucose meter: Ensure it's clean, calibrated, and has working batteries.
- Test strips: Make sure they are not expired and are compatible with your monitor.
- Lancet device: A device that holds a small needle (lancet) used to prick your finger.
- Lancets: New and unused for each test.
- Alcohol wipes or cotton ball and rubbing alcohol: To clean the finger prick site.
- Sharps disposal container: For safely discarding used lancets.
-
Wash Your Hands:
- Wash your hands thoroughly with soap and warm water, and dry them completely. This helps prevent inaccurate readings and reduces the risk of infection.
-
Prepare Your Lancing Device:
- Insert a new lancet into the lancing device.
- Adjust the depth of the lancing device according to your comfort, usually based on your skin type (thinner skin uses a lower setting and vice-versa).
-
Prepare the Test Strip:
- Remove a test strip from its container, and insert it into the blood glucose monitor. The meter should turn on automatically, or you may need to press a button. Check that the device is displaying the proper message, indicating readiness.
-
Choose Your Puncture Site:
- Avoid the tips or centers of your fingers, as these areas can be more sensitive. Choose the side of your fingertip, where it's less likely to hurt, and rotate puncture sites to avoid soreness over time. You can also consider alternate sites like the palm of your hand or forearm, but these readings might be slightly less accurate than fingersticks for monitoring fast changes.
-
Clean the Puncture Site:
- Wipe the chosen fingertip with an alcohol wipe and allow it to air dry. Do not blow on your finger, as this could contaminate the sample.
-
Puncture Your Finger:
- Place the lancing device firmly against the side of your fingertip, and press the trigger.
-
Obtain a Blood Sample:
- Gently squeeze or massage the finger from the base to the tip until you get a small drop of blood. Avoid squeezing too hard, as it could dilute your sample with tissue fluid.
-
Apply Blood to the Test Strip:
- Carefully touch the test strip's designated area to the blood droplet. The blood will be absorbed into the strip. The meter may beep, indicating the reading process is starting.
-
Wait for Results:
- Your blood sugar reading will be displayed on the monitor in a few seconds.
-
Record Your Reading:
- Note the time and the blood sugar result in a logbook, a mobile app, or another method of tracking readings. Keeping track helps you manage your diabetes well.
-
Dispose of Lancets Safely:
- Place the used lancet in the sharps container to prevent accidental pricks or infection to others.
- Remove and discard the used test strip.
- Clean the meter regularly with a slightly damp cloth (never use soap or immerse it in water).

Understanding Your Blood Sugar Readings
Understanding your blood sugar readings is crucial for making appropriate lifestyle and treatment decisions. Target blood sugar levels can vary depending on individual factors and overall treatment goals, so you must talk to your doctor. However, here are some general guidelines:
General Target Ranges:
- Before meals (Fasting): 80–130 mg/dL
- 1-2 hours after meals (Postprandial): Less than 180 mg/dL
- HbA1c Test: Less than 7.0%, which reflects your average blood glucose over the past three months.
Terms to Understand:
- Hyperglycemia: High blood sugar, usually above 180 mg/dL. Symptoms may include excessive thirst, frequent urination, and blurred vision.
- Hypoglycemia: Low blood sugar, usually below 70 mg/dL. Symptoms can include shaking, sweating, and dizziness. It's vital to treat this quickly with fast-acting glucose.
- Pre-diabetes: A condition where blood sugar levels are higher than normal but not yet high enough to be classified as type 2 diabetes. Early detection is critical for preventing progression to diabetes.
If You See Abnormal Blood Glucose Levels:
- High Readings: Consider adjusting your diet, exercise, or medication dosage in coordination with your healthcare provider.
- Low Readings: Eat or drink a fast-acting carbohydrate like glucose tablets, or juice, then test again in 15 minutes to make sure you are recovering. Consult your doctor if low glucose episodes are frequent or severe.
- Unusual Reading Check to make sure your test strip is good, that the reading was done at the proper time, and that you washed your hands well. Check a second time or use another device for comparison if your numbers do not seem normal.
| Condition | Target Range | Common Actionable Response |
|---|---|---|
| Fasting (Pre-meal) | 80-130 mg/dL | Plan meals, check medication, monitor patterns |
| Postprandial (1-2 hrs after meal) | Below 180 mg/dL | Check insulin dose, adjust carbohydrate consumption |
| Hyperglycemia (High) | Over 180 mg/dL | Consult doctor, adjust treatment, assess potential causes |
| Hypoglycemia (Low) | Below 70 mg/dL | Consume fast-acting carbohydrate, monitor closely |
