AGT and IgA glomerulonephritis: In patients with nephrotic range proteinuria, UAGT correlates with proteinuria (Jang et al., 2014; Tang et al., 2018).Plasma AGT correlates with UAGT in patients with nephrotic syndrome (Jang et al., 2014).No correlation between ACR and UAGT in minimal change disease (Tang et al., 2018).UAGT is increased in patients with AA amyloidosis compared with healthy controls (Kutlugün et al., 2012).The AGT/ACR ratio differentiates between TIN and IgA nephropathy (Ohashi et al., 2020).
