Monitoring blood sugar levels is crucial for people with diabetes and those at risk of developing it. Regular and accurate blood sugar testing helps manage diabetes effectively, prevent complications, and maintain overall health. Here’s a step-by-step guide on how to check your blood sugar the right way.
Why is Blood Sugar Monitoring Important?
Checking blood sugar regularly helps:
✔ Keep glucose levels within the target range
✔ Adjust diet, exercise, and medication accordingly
✔ Prevent complications like nerve damage, kidney disease, and heart problems
✔ Identify patterns in blood sugar fluctuations
When Should You Check Your Blood Sugar?
The frequency of blood sugar testing depends on individual health conditions and doctor recommendations. Common testing times include:
- Fasting (before breakfast) – Helps monitor baseline sugar levels
- Before meals – To assess pre-meal glucose levels
- After meals (postprandial) – To track how food affects sugar levels
- Before and after exercise – To check the impact of physical activity
- Before bedtime – To ensure stable overnight sugar levels

Step-by-Step Guide to Checking Blood Sugar
1. Gather Your Supplies
You’ll need:
✔ A blood glucose meter
✔ Test strips compatible with your meter
✔ A lancet (pricking device)
✔ Alcohol swab or soap and water
✔ A logbook or app to record results
2. Wash Your Hands
- Use warm water and soap to clean your hands.
- Dry them thoroughly, as moisture can dilute the blood sample and affect accuracy.
- Avoid using alcohol swabs regularly, as they can dry out the skin.
3. Insert the Test Strip
- Turn on your glucose meter and insert the test strip as per the manufacturer’s instructions.
4. Prick Your Finger
- Use a new lancet each time to prevent infection.
- Prick the side of your fingertip (not the center) to minimize pain.
- Gently squeeze your finger to get a small blood drop.
5. Apply Blood to the Test Strip
- Touch the blood drop to the strip and wait for the meter to display your blood sugar reading.
6. Record the Results
- Note the reading in a logbook or a mobile app.
- Include details like the time of day, meal intake, or exercise activity for better tracking.
Tips for Accurate Readings
✔ Use fresh test strips and store them properly.
✔ Check the expiration date on test strips.
✔ Avoid extreme temperatures while storing your meter.
✔ Calibrate your meter if required.
What Do Your Blood Sugar Readings Mean?
| Blood Sugar Level | Condition |
|---|---|
| 70-99 mg/dL | Normal fasting level |
| 100-125 mg/dL | Prediabetes |
| 126 mg/dL or higher | Diabetes (consult a doctor) |
| Below 70 mg/dL | Low blood sugar (hypoglycemia) |

When to Seek Medical Help?
📌 High Blood Sugar (Hyperglycemia): If readings consistently stay above 200 mg/dL, contact your doctor.
📌 Low Blood Sugar (Hypoglycemia): If sugar levels drop below 70 mg/dL, consume a quick source of sugar (juice, glucose tablets) and consult a doctor if symptoms persist.
Final Thoughts
Checking your blood sugar the right way ensures accuracy and helps in effective diabetes management. By following proper hygiene, using the correct technique, and tracking your readings, you can maintain better control over your health. Always consult a doctor for guidance on blood sugar targets and lifestyle adjustments.
