Lower GFR and higher urine albumin/creatinine ratio are independent risk factors for CKD progression. Still, the combination of these two tests provides the best estimate of the current status and future progression of the disease. In general:
- Higher ACR + lower eGFR = Increased Risk
Patients with risk factors for developing CKD are recommended to undergo laboratory tests at least annually to determine ongoing risk and monitor progression.
The National Kidney Foundation provides a cross-walk of the two risk factors, available at the link
