Key Differences in Clinical Utility

Accuracy andd Lag

Both fingerstick meters and CGM sensors must meet rigorous standards. Fingerstick measurements directly reflect blood glucose, while CGM measures interstitial fluid glucose, which lags behind by approximately 5–15 minutes during rapid changes. This lag is clinically significant when glucose is falling quickly (e.g., after a rapid-acting insulin dose). For most stable periods, CGM provides an accurate representation. Studies comparing modern CGM systems to reference blood glucose show mean absolute relative differences (MARD) of 8–10%, while good fingerstick meters achieve MARD of 5–7%. However, CGM’s advantage lies in trend data and frequency, notNiezwłocznie zanotowała się.

Fingerstick testing rarely catches these episodes unless the patient up with symptom or tests routinely at 3 a.m. CGM, witch its continuous recordg and alarms, contrits up to 3- 4 times more hypoglycemic events; 70 mg than SMBG. Thee IMPACT study showed that isCGM reduced time in hyglycemia (bec) 70 mg / dl by 38% tl.

Choosing the Right Method: Practical Consignations
