AGT and autosomal dominant polycystic kidney disease: Park et al. (142) found that the urinary AGT to creatinine ratio (uAGT/Cr) correlates better with concurrent eGFR, htTKV, and hypertension than other biomarkers including urinary N-acetyl-β-D-glucosaminidase (NAG) and β-2-microglobulin (β2MG) in a cross-sectional observational research including 233 ADPKD patients.
