Hi, glucometer readings are usually taken from capillary blood (fingertip), whereas lab tests use venous blood. Due to this, glucometer readings can vary by 10–15% compared to lab results. Other factors like device calibration, user technique, and food timing also affect accuracy. The lab result is generally more precise, but glucometer readings are useful for regular home monitoring.
