What are the most reliable surrogate markers for early diabetic nephropathy progression in primary care settings without access to advanced biomarker panels?

I am an internal medicine physician conducting primary care based research on diabetic nephropathy in Pakistan. In our setting, advanced biomarkers such as KIM-1, NGAL and cystatin C are unavailable. I am seeking expert consensus on which routinely available markers including urine ACR, eGFR trajectory, blood pressure patterns, and HbA1c best predict early CKD progression in T2DM patients in resource limited environment.

 The most reliable surrogate measures for primary care without sophisticated biomarker panels are serial urine ACR and serial eGFR, which are backed by trends in blood pressure and HbA1c. Persistent ACR ≥30 mg/g with either increasing albuminuria or decreasing eGFR is the greatest early warning pattern.
