Essential Equipment for Home Blood Sugar Testing
Before you start, make sure you have all the necessary supplies:
- Blood Glucose Meter: This device measures the amount of glucose in your blood sample. Different meters offer various features, such as memory storage, data transfer capabilities, and connectivity with mobile apps. Popular brands include OneTouch, Accu-Chek, and Contour. Choose one that is easy to use and fits your needs.
- Test Strips: These are single-use strips that you insert into the glucose meter. A small blood sample is applied to the strip, which then reacts with the chemicals on the strip to determine the blood sugar level. Always use test strips designed specifically for your meter model.
- Lancet Device and Lancets: The lancet device is a spring-loaded device that holds a lancet – a small, sterile needle used to prick your finger. Choose a lancet device with adjustable depth settings to minimize discomfort.
- Alcohol Swabs: These are used to clean the fingertip before pricking.
- Cotton Balls or Gauze Pads: Use these to stop the bleeding after testing.
- Sharps Container: A sturdy, puncture-resistant container is essential for safely disposing of used lancets and test strips. You can purchase a dedicated sharps container from a pharmacy or use a heavy-duty plastic container with a tight-fitting lid.
Step-by-Step Guide to Checking Your Blood Sugar
Follow these steps carefully to ensure accurate results and a safe testing experience:
- Wash Your Hands: Thoroughly wash your hands with soap and warm water. This helps remove any dirt or debris that could affect your blood sugar reading. Dry your hands completely.
- Prepare Your Equipment: Gather all your supplies and place them within easy reach. Make sure your blood glucose meter is turned on and ready to use.
- Insert a Test Strip: Insert a new test strip into the meter, following the instructions specific to your meter model. The meter will usually display a symbol indicating that it's ready for a blood sample.
- Prepare the Lancet Device: Load a fresh lancet into the lancet device. Adjust the depth setting to a comfortable level that provides an adequate blood sample.
- Choose a Finger: Select a fingertip to prick. It's best to use the sides of your fingers, as they are less sensitive than the tips. Rotate fingers each time you test to avoid soreness.
- Clean Your Fingertip: Clean the selected fingertip with an alcohol swab and let it air dry completely.
- Prick Your Finger: Place the lancet device against the side of your fingertip and press the release button. You should feel a quick prick.
- Obtain a Blood Sample: Gently squeeze or massage your finger near the puncture site to encourage a small drop of blood to form. Avoid squeezing too hard, as this can dilute the blood sample and affect the accuracy of the reading.
- Apply Blood to the Test Strip: Carefully touch the edge of the test strip to the drop of blood. The strip will draw the blood in through capillary action. Ensure that the strip is adequately filled with blood, as indicated by the meter instructions.
- Wait for the Reading: The meter will display your blood sugar level within a few seconds.
- Record Your Results: Write down your blood sugar reading, the date, the time of day, and any relevant information, such as meals, medications, or activities that may have affected your blood sugar level. This information is valuable for your healthcare provider.
- Dispose of the Used Lancet and Test Strip: Immediately dispose of the used lancet in a sharps container. Remove the used test strip from the meter and discard it according to your local regulations.
- Clean Up: Apply a cotton ball or gauze pad to the puncture site to stop any bleeding. Clean the meter and lancet device according to the manufacturer's instructions.
Understanding Your Blood Sugar Results
Your blood sugar readings will vary depending on the time of day, your food intake, and other factors. Here's a general guideline for target blood sugar levels for adults with diabetes, as recommended by the American Diabetes Association:
- Before Meals: 80-130 mg/dL
- 1-2 Hours After Starting a Meal: Less than 180 mg/dL
Note: These are general guidelines, and your target blood sugar levels may be different based on your individual health status and treatment plan. Discuss your specific targets with your healthcare provider.
If your blood sugar readings are consistently high or low, or if you experience any symptoms of hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), contact your healthcare provider immediately.
Tips for Accurate Blood Sugar Testing
To ensure accurate and reliable results, keep the following tips in mind:
- Use Fresh Test Strips: Expired or damaged test strips can give inaccurate readings. Always check the expiration date on the test strip vial and store the strips properly in a cool, dry place.
- Clean Your Meter Regularly: Follow the manufacturer's instructions for cleaning your blood glucose meter to remove any dirt or debris that could affect its performance.
- Control Solution Checks: Periodically use control solution to verify that your meter and test strips are working correctly. Follow the instructions in your meter's user manual.
- Proper Blood Sample Size: Ensure that you obtain an adequate blood sample for the test strip to function properly. Insufficient blood can lead to inaccurate readings.
- Avoid Contamination: Prevent contamination of the test strip and blood sample by washing your hands thoroughly and using clean equipment.
- Calibrate Your Meter: Some meters require calibration, so be sure to follow the manufacturer's instructions regarding calibration procedures.
Common Mistakes to Avoid
Avoid these common mistakes when checking your blood sugar:
- Using Expired or Damaged Test Strips.
- Not Washing Your Hands Properly.
- Using Too Much or Too Little Blood.
- Squeezing Your Finger Too Hard.
- Ignoring Meter Error Messages.
- Not Storing Your Supplies Properly.
Choosing the Right Blood Glucose Meter
Selecting the right blood glucose meter is an important step in managing your blood sugar levels effectively. Consider these factors when making your choice:
- Ease of Use: Look for a meter that is easy to handle, read, and operate, especially if you have limited dexterity or vision.
- Accuracy: Choose a meter that has been shown to provide accurate results. Read reviews and consult with your healthcare provider to find a reliable meter.
- Features: Consider the features that are important to you, such as memory storage, data transfer capabilities, connectivity with mobile apps, and the ability to track trends over time.
- Cost: Consider the cost of the meter itself, as well as the ongoing cost of test strips and lancets.
- Insurance Coverage: Check with your insurance provider to see if your preferred meter and test strips are covered under your plan.
Blood Sugar Log: Tracking Your Readings
Maintaining a blood sugar log is a helpful way to monitor your progress and identify patterns in your blood sugar levels. You can use a paper logbook or a digital app to record your readings. Your blood sugar log should include the following information:
- Date and Time
- Blood Sugar Reading
- Meal or Activity (e.g., before breakfast, after lunch, after exercise)
- Medication (if applicable)
- Notes (any relevant information, such as stress levels, illness, or unusual symptoms)

Sharing your blood sugar log with your healthcare provider can help them assess your overall diabetes management and make any necessary adjustments to your treatment plan.
