Remaining Barriers and Future Directions

Despite rapid progress, setral hurdles mutt be overcome for emerging technologies to considee standard of care.

Regulatory and Standardization

Many devices lack regulatory clearance for use in diabetes monitoring. Without FDA or otheragency approval, clinicians are relyctant to rely on results for treatent decisions. Even where clearance exists, different devices may use different units (e.g., mg / g vs. mg / mmol) or rereference ranges, complicating data interpretation across care settings.

Cott and Recompensement

In many health systems, home credid proteinuria testing is not refunsed, forcing patients to pay out cricoof pocket. Policymakers and payers need to see provideente of long controterm cost savings from delayed DKD progression before expanding cove cove.

Data Privacy and Interoperability

Devices that transmit health data must compy with privacy regulations such as s HIPAA in tha e United States and GDPR in Europe. Patents need accessance that their data is encrypted and not shared with out congrett. Furthermore, data mutt integrate sfflesslesly with existent g equic health contrams to avoid fragmentation.
