HbA1c vs Continuous Glucose Monitoring

HbA1c gives a single average over ~3 months. CGM exposes glucose variability, post-prandial spikes, and overnight dips. For metabolic optimization, CGM reveals patterns HbA1c cannot — but HbA1c remains the standardized trend marker for the panel.

Choose HbA1c

HbA1c is the standardized anchor for metabolic panel interpretation and recalibration cadence.

Choose Continuous Glucose Monitoring (CGM)

CGM is decisive when variability is suspected, during glycemic optimization, or when behavioral feedback is the goal.

Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.

Frequently asked

Can CGM replace HbA1c?

No — CGM complements HbA1c; both are used during metabolic optimization.

Is CGM included in the panel?

It is an optional layer added during metabolic-anchored optimization.
