Chinese guidelines recommend that patients with type 1 diabetes mellitus (T1DM) with a course of more than 5 years and newly diagnosed type 2 diabetes mellitus (T2DM) patients should be tested for urinary albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR), to enable early detection of DKD, and should be screened at least once a year thereafter [9]. This evidence concerns the gene ALB and diabetes mellitus.
