Sometimes, you may notice a difference between your BUZUD CGM reading and your fingerstick blood glucose value. Don't worry—this difference is usually temporary and often resolves over time. Here are some common reasons why this may occur:

1. First Day of Sensor Use

During the first 24 hours after inserting a new BUZUD CGM sensor, readings may be less consistent compared to your blood glucose meter. This is normal and should stabilize as the sensor settles.

2. Rapid Glucose Changes

When your glucose levels are rising or falling quickly, it's harder to compare CGM readings with blood glucose meter results. This is because:

  • Blood glucose meters measure glucose in capillary blood
  • BUZUD CGM measures glucose in interstitial fluid

Blood glucose levels typically change slightly earlier than interstitial fluid glucose. Once your glucose levels stabilize, the readings from both methods should align more closely.

3. Pressure on the Sensor

If your BUZUD CGM sensor is under pressure—such as when lying on it or if tight clothing presses against it—it may cause inaccurate readings. Once the pressure is relieved, the readings should return to normal.

Rather than relying on a single reading, monitor your BUZUD CGM values over several hours to better understand the trend and determine the appropriate action.

If Your CGM Reading Does Not Match Your Symptoms

  1. Wash your hands thoroughly with soap and water
  2. Dry your hands completely
  3. Use your blood glucose meter to take a fingerstick reading
  4. If the meter value matches your symptoms, use the meter value to make treatment decisions

If discrepancies continue or worsen, contact BUZUD customer support or your healthcare provider to evaluate your sensor's performance.
