Master the fundamentals of blood sugar testing with our comprehensive preparation checklist. Proper preparation ensures accurate results every single time.
A quick equipment verification prevents testing errors and ensures reliable readings:
Test strips expire 6 months after opening, regardless of printed date
Ensure meter has sufficient power for testing
Store equipment at room temperature (68-77°F)
Verify test strips match your meter brand and model
Date Your Test Strips: Write the opening date on your test strip vial with a permanent marker. This simple habit prevents using expired strips that can give inaccurate readings up to 50% off your actual blood sugar!
This is the most critical step for accurate results. Even microscopic food residue can affect readings by hundreds of points.
Food residue is invisible but devastating: Research shows that touching a banana peel can raise readings by over 200 mg/dL! Even "clean" hands may have microscopic sugars that skew results.
Always wash hands immediately before testing, not minutes before.
