Why Accurate Blood Glucose Testing Matters
For people living with diabetes, accurate blood glucose readings are the foundation of effective self-management. A single incorrect reading can lead to the wrong insulin dose, missed hypoglycemia, or unnecessary worry. Using your meter correctly every time is not just good practice β it can be life-changing.
What You Need Before You Start
- A calibrated blood glucose meter
- Compatible test strips (always check expiration dates)
- A lancing device with a fresh lancet
- Alcohol wipes or soap and water
- A sharps disposal container
MDS Diabetes carries a wide selection of meters, test strips, and lancing devices so you can stock up on everything you need in one place at mdsdiabetes.com.
Step-by-Step Guide to Testing Your Blood Glucose
Step 1: Wash and Dry Your Hands
Always wash your hands with warm soap and water before testing. Residue from food β especially fruit β can dramatically inflate your reading. Dry thoroughly, as water can dilute your blood sample.
Step 2: Prepare Your Lancing Device
Insert a fresh lancet into your lancing device and set the depth dial. A shallower setting is usually sufficient for most people. Never reuse lancets β they become dull quickly and increase discomfort and infection risk.
Step 3: Insert a Test Strip
Insert a new test strip into your meter. Most modern meters will power on automatically. Confirm the code on your strips matches the meter if your device requires coding.
Step 4: Lance Your Fingertip
Use the side of your fingertip rather than the pad β it is less sensitive and has good blood flow. Rotate testing sites to avoid soreness and calluses over time.
Step 5: Apply Blood to the Strip
Gently squeeze your finger to encourage a small blood drop. Touch the blood drop to the tip of the test strip β do not smear it. Most strips require only a tiny 0.5β1 microliter sample.
Step 6: Read and Record Your Result
Your result will display within 5 seconds on most meters. Log the reading in a diabetes journal or a smartphone app, noting the time, whether it was before or after a meal, and any relevant notes.
Common Mistakes That Affect Accuracy
- Using expired test strips
- Testing with cold or wet hands
- Not calibrating or coding your meter when required
- Storing strips in humid or hot environments
- Squeezing the finger too hard, which dilutes the sample with tissue fluid
Caring for Your Meter
Keep your meter clean by wiping it with a slightly damp cloth. Store it at room temperature away from direct sunlight. Replace batteries promptly to avoid inaccurate readings. Check your meter's accuracy periodically using the control solution included with your strips.
Choosing the Right Meter and Supplies
Not all meters suit every lifestyle. Consider factors like strip cost, sample size, memory capacity, and Bluetooth connectivity for data sharing with your healthcare provider.
